Overview** ASTM A414 Grade C (with composition specified) is a standard specification for **carbon steel sheets** intended for fusion-welded pressure vessel applications. It represents the **highest strength grade within the ASTM A414 family**, designed for applications where greater load-bearing capacity is required while still utilizing sheet or strip forms. The **"Composition Specified"** designation signifies that the material's acceptance is based primarily on conformance to defined chemical composition limits. Under this ordering condition, the mechanical properties (tensile and yield strength) are developed through the manufacturing process and are reported for information, but are **not mandatory requirements for material acceptance**. This provides flexibility for producing formable, weldable sheet with consistent metallurgical characteristics. ### **2. Chemical Composition (Weight %, Heat Analysis)** Per ASTM A414/A414M. Chemical composition is the primary control criterion for this ordering specification. | Element | Minimum (%) | Maximum (%) | Notes | |---------|------------|------------|-------| | **Carbon (C)** | - | 0.28 | The highest maximum carbon content in the A414 sheet family, providing increased strength through solid solution and pearlite content. Requires attention to weldability. | | **Manganese (Mn)** | 0.90 | 1.30 | The highest manganese range among A414 grades. This significant Mn content is the primary driver for achieving higher strength while contributing to hardenability. | | **Phosphorus (P)** | - | 0.035 | Standard impurity control for pressure vessel quality steel. | | **Sulfur (S)** | - | 0.040 | Standard impurity control; affects hot workability and weldability. | | **Silicon (Si)** | 0.15 | 0.30 | Ensures the steel is fully killed (deoxidized), promoting a uniform and sound internal structure essential for the integrity of formed parts under higher stress. | | **Copper (Cu)** *when specified* | 0.20 | - | Optional element; can be specified to enhance atmospheric corrosion resistance. | **Key Distinction:** For "Composition Specified" Grade C, **conformance to the above chemical limits is mandatory**. The tensile and yield strength values result from the controlled chemistry and rolling process. They are reported but are not the contractual basis for acceptance. This contrasts with "Physical Specified" orders, where mechanical properties are the mandatory acceptance criteria. ### **3. Physical & Mechanical Properties** *Properties are typical for commercially produced hot-rolled or cold-rolled sheet meeting the composition specification.* **Reported Mechanical Properties (Typical, for information):** * **Tensile Strength (Rm):** 55,000 - 75,000 psi (380 - 515 MPa) [Reported Value] * **Yield Strength (Re, 0.2% offset):** 30,000 - 40,000 psi (205 - 275 MPa) [Reported Value] * **Elongation (A, min in 2 in.):** 20% min (Typical expectation) **Impact Properties:** * **Not Required:** ASTM A414 does **not** require Charpy V-notch impact testing. Consequently, it is **not suitable for low-temperature service** where risk of brittle fracture exists. Its use is generally restricted to temperatures above 32°F (0°C). Its higher carbon and manganese content also increase susceptibility to brittle behavior if misapplied. **Physical Properties (Typical):** * **Density:** 0.284 lb/in³ (7.85 g/cm³) * **Modulus of Elasticity:** 29 x 10⁶ psi (200 GPa) * **Thermal Conductivity:** ~ 48 W/m·K (at 20°C) ### **4. Key Characteristics** * **High Strength in Sheet Form:** Provides the maximum strength available in the A414 specification, allowing for thinner wall designs in pressure vessels made from sheet, potentially reducing weight and material cost. * **Chemistry-Driven High Strength:** The combination of high manganese (0.90-1.30%) and elevated carbon (up to 0.28%) is the primary mechanism for achieving its enhanced strength level. * **Good Formability (with consideration):** Suitable for the forming operations typical of pressure vessel sheet fabrication (e.g., rolling, pressing), though its higher strength and carbon content necessitate more force and careful attention to bend radii compared to Grades A and B. * **Weldability (Requires Procedure Control):** The higher carbon equivalent requires careful welding practices. Use of low-hydrogen processes, possible pre-heat (for thicker gauges or restrained joints), and proper heat input control are essential to avoid hydrogen-induced cracking and excessive HAZ hardness. * **Fully Killed Steel:** The mandatory silicon content ensures a sound, homogeneous microstructure. ### **5. Product Applications** ASTM A414 Grade C (Comp Spec) is used in pressure vessel applications where higher strength is required but component geometry dictates the use of sheet material: * **High-Pressure Receivers:** Air receivers and gas storage vessels designed for higher working pressures. * **Boiler Components:** Shells and drums for firetube boilers operating at higher pressures. * **Formed Heads for Thinner-Walled Vessels:** Where the higher strength of Grade C allows for a reduction in head thickness compared to using Grade A or B. * **Process Vessels:** Columns, separators, or scrubbers fabricated from sheet where internal pressure or external loads require higher material strength. * **Transportable Pressure Vessels:** DOT-spec tanks where weight savings are critical, though specific DOT specs may override. ### **6. International Standards & Specifications** | Region | Standard & Designation | Scope / Notes | |--------|----------------------|---------------| | **USA / ASTM** | **ASTM A414/A414M** | Standard Specification for **Carbon Steel Sheet** for Pressure Vessels. Covers Grades A through G. | | **USA / ASME** | **ASME SA-414** | Identical adoption into the ASME Boiler and Pressure Vessel Code for construction. | | **European Union (EU)** | **EN 10028-2** | A comparable product in terms of strength might be **P295GH** or **P305GH** sheet, though these EN grades are typically normalized plates with guaranteed impact properties. | | **International / ISO** | **ISO 9328-2** | Similar strength grades like **P295GH** serve as functional equivalents but are typically specified as normalized plates. | | **Japan** | **JIS G3116 SPV 355** | Steel for pressure vessels with a comparable tensile strength range. | **Critical Note:** ASTM A414 is specifically for **sheet** products. For **plate** applications with similar or higher strength and mandatory toughness, specifications like **ASTM A516 Grade 60/65** are the standard choice. ### **7. Available Forms & Processing** * **Standard Forms:** Supplied as **sheets** (cut lengths) or **strip** (coils). * **Condition:** Typically supplied as **hot-rolled** or **cold-rolled**. * **Fabrication:** * **Forming:** Capable of cold forming, but may require intermediate annealing for severe deformations. Hot forming is an alternative for complex shapes. * **Welding:** **Requires a qualified Welding Procedure Specification (WPS).** Use low-hydrogen electrodes (e.g., E7018), control interpass temperature, and consider pre-heat for thicknesses above approx. 3/16 inch (5 mm). * **Post-Weld Heat Treatment (PWHT):** Often recommended to relieve residual stresses, especially for thicker sections or highly restrained joints. ### **8. Selection Guidance** **Choose ASTM A414 Grade C (Comp Spec) when:** * Fabricating vessel components from **sheet material** where the **highest available strength in the A414 series** is needed. * The design aims to **minimize wall thickness** for weight or cost savings within the sheet product range. * The application is for **ambient temperature, moderate to high-pressure service** (within the limits of sheet construction). * You can implement and control the **necessary welding procedures**. **Do NOT select this grade if:** * The application involves **low temperatures** (below 32°F/0°C). * **Guaranteed minimum yield/tensile strength** is a code requirement for the material purchase (choose "Physical Specified" Grade C or a plate spec like A516). * **Superior notch toughness** is required (choose an impact-tested grade like A516). * Maximum ease of forming and welding is the top priority (choose Grade A or B). --- **Disclaimer:** This technical summary is for informational purposes. **ASTM A414 Grade C is not intended for low-temperature service and requires careful welding procedure control.** When ordering "Composition Specified" material, the fabricator assumes responsibility for the resulting mechanical properties in the final fabricated product. All pressure vessel construction must comply with the applicable design code (e.g., ASME Section VIII), which governs material selection, design, fabrication, and inspection. Always consult the latest **ASTM A414/A414M** specification and involve a qualified materials/welding engineer. -:- For detailed product information, please contact sales. -: ASTM A414 Grade C Pressure Vessel Steel, Composition Spec Specification Dimensions Size： Diameter 20-1000 mm Length <7391 mm Size:We can customized as required Standard： Per your request or drawing We can customized as required Properties（Theoretical） Chemical Composition -:- For detailed product information, please contact sales. -: ASTM A414 Grade C Pressure Vessel Steel, Composition Spec Properties -:- For detailed product information, please contact sales. -:
