Product Overview & Specification** **ASTM A611** is an international technical standard published by **ASTM International** under the full title "*Standard Specification for Structural Steel (Cold-Formed), Carbon, Cold-Rolled*". This specification covers cold-rolled carbon steel sheets produced in the **as-cold-rolled condition** (not annealed after final reduction) specifically engineered for structural applications. **Grade C** represents the **intermediate-high strength grade** within this specification family, positioned between the general-purpose Grade B and the high-strength Grades D/E. It provides enhanced load-bearing capacity while maintaining adequate formability for most structural fabrication processes. ### **2. Key Material Characteristics** - **Manufacturing Process:** Produced via cold reduction without subsequent thermal annealing, resulting in strain-hardened mechanical properties - **Structural Integrity:** Designed specifically for calculated structural members requiring verified mechanical properties - **Surface Quality:** Exhibits superior surface finish (typical Ra < 1.0 µm) compared to hot-rolled equivalents - **Dimensional Precision:** Maintains tight thickness tolerances (±0.005" typical) critical for precision fabrication - **Formability Balance:** Optimized chemistry provides sufficient ductility despite higher strength levels ### **3. Chemical Composition Requirements** ASTM A611 does not mandate rigid chemical composition limits; producers optimize chemistry to achieve specified mechanical properties. Grade C typically employs microalloying and controlled processing to attain its higher strength. | Element | Typical Composition Range (%) | Primary Function | |---------|-------------------------------|------------------| | **Carbon (C)** | 0.08 - 0.20 | Primary strengthener | | **Manganese (Mn)** | 0.60 - 1.00 | Solid solution strengthening | | **Phosphorus (P)** | ≤ 0.035 | Residual element control | | **Sulfur (S)** | ≤ 0.030 | Improved machinability | | **Silicon (Si)** | 0.05 - 0.30 | Deoxidizer | | **Aluminum (Al)** | 0.01 - 0.08 | Grain refinement | | **Microalloys** | V, Nb, Ti (optional) | Precipitation hardening | *Note: Chemistry may vary by manufacturer and specific processing route.* ### **4. Mechanical & Physical Properties** #### **Minimum Required Mechanical Properties (Transverse Specimens):** - **Yield Strength (0.2% offset):** **50 ksi minimum (345 MPa)** - **Tensile Strength:** **62 ksi minimum (427 MPa)** - **Elongation in 2-inch gauge length:** - Thickness < 0.056 in. (1.42 mm): **18% minimum** - Thickness ≥ 0.056 in. (1.42 mm): **20% minimum** #### **Typical Physical Properties:** - **Density:** 0.284 lb/in³ (7,850 kg/m³) - **Modulus of Elasticity (E):** 29,000 ksi (200 GPa) - **Shear Modulus:** 11,500 ksi (79 GPa) - **Poisson's Ratio:** 0.29 - **Coefficient of Thermal Expansion:** 6.5×10⁻⁶/°F (11.7×10⁻⁶/°C) - **Thermal Conductivity:** 28 Btu·in/(hr·ft²·°F) [45 W/(m·K)] ### **5. Material Availability & Processing** **Available Forms:** - **Coils:** Widths 24-72 inches, thickness 0.015-0.135 inches - **Sheets:** Cut-to-length, maximum sheet size dependent on mill capability - **Surface Finish:** Commercial bright (B), matte (M), or specified roughness **Fabrication Considerations:** - **Weldability:** Good with standard processes (GMAW, GTAW, RW) - **Formability:** Suitable for moderate bending (minimum bend radius ~2.5×t) - **Machinability:** Fair to good with proper tooling and speeds - **Painting:** Excellent surface for coating adhesion after proper cleaning ### **6. Primary Applications** **Structural Framing Systems:** - Heavy-duty storage rack uprights and beams - Industrial mezzanine framing components - Commercial building curtain wall supports - Highway sign support structures **Transportation Equipment:** - Truck trailer frame rails and crossmembers - Bus roll-bar structures and floor supports - Railroad car interior structural members - Material handling equipment frames **Industrial Components:** - Machine base frames and enclosures - Agricultural equipment structural members - Commercial refrigeration unit frames - Heavy-duty shelving and storage systems **Construction Products:** - Structural roof purlins (heavy-load applications) - Load-bearing wall studs in modular construction - Bridge deck forming supports - Temporary shoring system components ### **7. Comparative Analysis** **Within ASTM A611 Family:** - **vs. Grade A (33 ksi):** 50% higher yield strength, reduced elongation - **vs. Grade B (40 ksi):** 25% strength increase, similar formability - **vs. Grade D/E (80 ksi):** Lower strength but significantly better formability and weldability **Competitive Materials:** - **ASTM A653 SS Grades:** Galvanized equivalents with corrosion protection - **ASTM A1011 HSLAS:** Hot-rolled alternatives with similar strength - **ASTM A1008 CS Types:** Annealed cold-rolled with different properties ### **8. Quality Assurance & Testing** **Certification Requirements:** - Mill test reports confirming chemical and mechanical properties - Dimensional compliance per ASTM A568 - Surface quality per ASTM A924 **Standard Testing Methods:** - Tension testing per ASTM A370 - Bend testing per ASTM E190/E290 - Hardness testing optional per ASTM E18 ### **9. Design & Specification Guidelines** **Key Design Parameters:** - Minimum yield strength: 50 ksi for all calculations - Use net section properties for cold-formed members - Consider reduced ductility compared to lower grades - Account for possible anisotropy (directionality of properties) **Specification Language:** ``` Steel Sheet: ASTM A611, Grade C, Cold-Rolled Thickness: [Specify] inches/mm Width: [Specify] inches/mm Surface Finish: [Specify B, M, or other] Mechanical Properties: 50 ksi min yield, 62 ksi min tensile ``` ### **10. Global Equivalents & References** **International Standards:** - **EN 10149-2:** S500MC (similar application) - **JIS G 3135:** SPFC 590 (approximate equivalent) - **GB/T 20564.4:** CR550/600DP (similar grade range) **Related Specifications:** - **AISI S100:** North American Cold-Formed Steel Design - **ASCE 8:** Specification for Cold-Formed Steel Construction - **AISC 360:** Steel Construction Manual (references) ### **Conclusion** ASTM A611 Grade C provides an **optimal balance of strength and fabricability** for structural applications requiring 50 ksi yield strength. Its cold-rolled manufacturing ensures excellent surface quality and dimensional consistency, while its controlled chemistry delivers reliable mechanical properties. This grade is particularly valuable in applications where **weight reduction** is desired without sacrificing structural integrity, making it a preferred choice for transportation, storage, and industrial equipment manufacturers worldwide. Engineering selection of Grade C should consider its specific formability limitations compared to lower grades, while recognizing its advantages over hot-rolled alternatives in surface-sensitive applications. Proper fabrication techniques and design methodologies specific to cold-formed, high-strength steel should be employed to ensure optimal performance. -:- For detailed product information, please contact sales. -: ASTM A611 Steel, grade C Specification Dimensions Size： Diameter 20-1000 mm Length <5945 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 A611 Steel, grade C Properties -:- For detailed product information, please contact sales. -:
