It is part of the "A" series within the ASTM A131 specification ("Structural Steel for Ships"), with "H36" denoting a minimum yield strength of 36 ksi (250 MPa) and enhanced impact toughness at ambient or sub-zero temperatures. AH36 steel is renowned for its excellent combination of strength, toughness, weldability, and corrosion resistance, making it a primary material choice for critical structures in harsh maritime environments. **Key International Standards** * **Primary Standard:** **ASTM A131/A131M** - Standard Specification for Structural Steel for Ships * **Equivalent/Near-Equivalent Grades:** * **EN 10025-6:** S355N (Similar strength, but chemical composition and specific toughness requirements may differ) * **ABS (American Bureau of Shipping):** ABS Grade AH36 * **DNV (Det Norske Veritas):** NV NS36 * **LR (Lloyd's Register):** Grade AH36 * Note: For maritime construction, the steel must typically be produced and supplied with approval from a recognized classification society (e.g., ABS, DNV, LR, BV). **Chemical Composition (Typical % by Weight, ASTM A131)** The chemical composition is carefully balanced to achieve the desired mechanical properties and weldability. | Element | Content (Maximum, %) | Role & Effect | | :--- | :--- | :--- | | **Carbon (C)** | 0.18 | Provides strength. Kept low to ensure good weldability and toughness. | | **Manganese (Mn)** | 0.90 - 1.60 | Increases strength and hardenability, improves hot-working properties. | | **Silicon (Si)** | 0.10 - 0.50 | Deoxidizer during steelmaking, contributes to strength. | | **Phosphorus (P)** | 0.035 max | Impurity; kept low to prevent cold brittleness. | | **Sulfur (S)** | 0.035 max | Impurity; kept low to improve hot workability and toughness. | | **Aluminum (Al)** | 0.015 min (for fine grain) | Grain refiner, essential for achieving good toughness. | | **Niobium (Nb)** | 0.02 - 0.05 | Micro-alloying element; provides grain refinement and precipitation strengthening. | | **Vanadium (V)** | 0.05 - 0.10 | Micro-alloying element; contributes to strength through precipitation hardening. | | **Nitrogen (N)** | 0.012 max | Controlled to prevent aging and brittleness. | (Note: Specific limits, especially for micro-alloys, may vary by thickness and manufacturer. The steel is typically supplied in the normalized or thermomechanically controlled processed (TMCP) condition.) **Physical & Mechanical Properties** | Property | Typical Value | Test Standard / Condition | | :--- | :--- | :--- | | **Yield Strength (Min)** | 36 ksi (250 MPa) | ASTM A370 | | **Tensile Strength** | 58 - 71 ksi (400 - 490 MPa) | ASTM A370 | | **Elongation (Min)** | 20% (in 8 in.) / 22% (in 50 mm) | ASTM A370 | | **Charpy V-Notch Impact Toughness** | Varies by grade suffix and thickness. Commonly required at **-20°C (-4°F)** or **0°C (32°F)**. Minimum average energy is typically **34 J (25 ft-lbf)** for longitudinal specimens. | ASTM A370 / ASTM A673 (Frequency of testing) | | **Density** | 7.85 g/cm³ (0.284 lb/in³) | - | | **Modulus of Elasticity** | 29,000 ksi (200 GPa) | - | | **Poisson's Ratio** | 0.29 | - | **Product Forms & Applications** AH36 steel is supplied in various forms to suit different construction needs: * **Plates:** The most common form, used in primary hull structures. * **Sections (Bars, Shapes):** For frames, stiffeners, and support structures. * **Applications:** * **Shipbuilding:** Hull plating, decks, bulkheads, and critical structural members of cargo ships, tankers, container vessels, and naval ships. * **Offshore Oil & Gas:** Platforms (jackets, topsides), floating production storage and offloading (FPSO) vessels, modules, and subsea structures. * **Bridge Construction:** Particularly for bridges in coastal or marine environments. * **Other Heavy Structures:** Where high strength-to-weight ratio and corrosion resistance are advantageous. **Advantages of ASTM A131 Grade AH36** * **High Strength-to-Weight Ratio:** Allows for lighter, more efficient structures without compromising integrity. * **Excellent Toughness:** Reliable performance in low-temperature marine environments, resisting brittle fracture. * **Good Weldability:** The controlled low carbon equivalent (CE) facilitates common welding techniques without pre- or post-heat treatment in most cases. * **Proven Durability:** Meets rigorous international marine classification standards for safety and longevity. * **Availability:** Widely produced and available globally through mills approved by major classification societies. In summary, **ASTM A131 Grade AH36** is a premium, standardized marine-grade steel that forms the backbone of modern maritime infrastructure, delivering the necessary performance and reliability for safety-critical applications at sea. -:- For detailed product information, please contact sales. -: ASTM A131 Steel, Grade AH36 Specification Dimensions Size： Diameter 20-1000 mm Length <5966 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 A131 Steel, Grade AH36 Properties -:- For detailed product information, please contact sales. -:
