ASTM A516 GR 65 (ASTM A516GR65) Carbon Steel Plates

ASTM A516 Grade 65, also known as ASTM A516GR65 or ASTM A516 GR 65, is a high-strength carbon steel plate designed for moderate and lower temperature pressure vessels, boilers, and storage tanks. This grade offers excellent tensile strength of 450-585 MPa and yield strength of 240 MPa, making it suitable for applications requiring enhanced toughness and weldability. SHH STEEL supplies these plates in thicknesses from 5mm to 500mm, with widths up to 4600mm and lengths to 12000mm, ensuring versatility for large industrial projects. The material’s fine grain structure, achieved through normalizing heat treatment, enhances ductility and impact resistance, preventing brittle failure in demanding environments. For buyers searching for ASTM A 516 GR 65 properties or equivalents, this grade excels in cost-effectiveness and compliance with ASME Section VIII, which governs pressure-containing equipment. SHH STEEL’s ASTM A516 GR.65 plates are rigorously tested for impact resistance and ultrasonic inspection, guaranteeing defect-free performance.

ASTM A516 Grade 65 carbon steel plates are specified under ASTM A516/A516M-17, a standard for pressure vessel steel, and comply with ASME Section II Part A (SA-516 Gr.65) for boiler and pressure vessel code applications. SHH STEEL adheres to this specification, offering plates in normalized or stress-relieved conditions to optimize mechanical properties. The standard supports widths up to 4600mm and lengths up to 12000mm, with custom dimensions available for large-diameter vessel requirements. Ultrasonic examination per ASTM A435 or A577 detects laminations, ensuring defect-free material, while dual certification with EN 10028-2 or GB/T 713 is provided for international projects. This flexibility makes our ASTM A516 GR 65 plates suitable for diverse needs, supported by mill test certificates for traceability.

The chemical composition of ASTM A516 Grade 65 is tightly controlled per ASTM A516/A516M-17 to ensure weldability, toughness, and corrosion resistance. Low carbon (≤0.24%) prevents brittleness, manganese (0.85-1.20%) enhances strength, phosphorus and sulfur (≤0.035%) reduce cracking risks, and silicon (0.15-0.40%) aids deoxidation. Optional elements like vanadium (≤0.02%) refine grains for better impact resistance. SHH STEEL maintains CE (Carbon Equivalent) ≤0.41 per AWS D1.1, making ASTM A516 GR 65 plates a reliable choice for buyers searching for “ASTM A516 GR 65 chemical composition.”

ASTM A516 Grade 65 carbon steel plates exhibit robust mechanical properties, tested per ASTM E8 for tensile/yield, ASTM E23 for impact, and ASTM E466 for fatigue, making them suitable for pressure vessel service. The minimum yield strength of 240 MPa and tensile range of 450-585 MPa ensure high load-bearing capacity, with 19% elongation providing ductility for forming. Low-temperature impact of 27J at -20°C prevents brittle failure, while the modulus of elasticity (200 GPa per ASTM E111) supports structural stability. Fatigue limit (240 MPa est. per ASTM E466) varies with surface finish, optimized by SHH STEEL’s grinding. These properties make ASTM A516 GR.65 plates a top choice for buyers searching for “ASTM A516 GR.65 mechanical properties,” offering reliable performance in high-pressure environments.

Delivery conditions for ASTM A516 GR 65 carbon steel plates define their mechanical state, impacting suitability for pressure vessel fabrication. SHH STEEL supplies plates in as-rolled, normalized (900-950°C), or stress-relieved (620-650°C) conditions per ASTM A20/A20M, with quenched and tempered options for enhanced toughness. Normalized plates refine grain for improved impact resistance in boilers up to 450°C. Stress-relieved reduce residual stresses for welded structures, while quenched and tempered (870-900°C quench, 650°C temper) suit wear applications. Heat numbers ensure traceability, with SHH STEEL offering rapid global transit.

Tolerances for ASTM A516 GR 65 carbon steel plates are crucial for precision in fabrication, minimizing fit-up issues. SHH STEEL adheres to ASTM A6/A6M, with ±1.5mm thickness tolerance for plates under 40mm and ±2.0mm for thicker sections up to 200mm (custom 300mm). Width and length tolerances are ±10mm standard, with ±5mm for precision orders up to 4600mm width and 12000mm length. Surface flatness is 3mm per meter, per ASTM A6, preventing warping. For European projects, EN 10029 Class B tolerances are offered, enhancing compatibility.

ASTM A516 GR 65 carbon steel plates are highly weldable due to low carbon (≤0.24%) and CE ≤0.41 per AWS D1.1. SHH STEEL recommends preheating at 150-200°C for thicknesses over 25mm to prevent cracking, with post-weld heat treatment (PWHT) at 620-650°C for stress relief. Processes like GTAW, SMAW, and GMAW are supported with E7018 filler (AWS A5.1), achieving 90-95% joint efficiency per ASME Section IX. Low sulfur (≤0.035%) reduces hot shortness, and 19% elongation ensures ductility. Testing includes bend tests (ASTM E190) for 3t radius and ultrasonic for weld integrity per ASTM A435.

Global equivalents for ASTM A516 Gr.65 facilitate international projects, offering similar tensile and yield properties for pressure vessel use.

Supplementary requirements for ASTM A516 GR 65 carbon steel plates enhance performance for specialized applications, offering buyers tailored options. These include ultrasonic testing (Class 1 per ASTM A435 for no laminations >0.25% thickness), Charpy impact at -50°C (27J min per ASTM A20 for cold service), and heat analysis per heat number (ASTM E350 for traceability). Product analysis allows ±0.02% tolerance on elements, while shot blasting to Sa 2.5 (50-100μm profile per ISO 8501-1) is available for surface preparation. SHH STEEL provides these to meet stringent needs, as buyers search for “A516 Gr.65 supplementary requirements.”

ASTM A516 GR 65 carbon steel plates are versatile for high-pressure and temperature environments, with excellent strength and toughness.

Details: Pressure vessels benefit from 450-585 MPa tensile at 450°C, while boilers handle 400°C with 19% elongation for forming. Storage tanks use 5-30mm plates for 50 bar, and oil & gas equipment leverages 30-120mm for 400 bar with NACE compliance. Heat exchangers utilize 10-40mm plates for 200 bar at 300°C, per TEMA standards for efficient heat transfer.
