ASME SA 516 Gr 70 vs SA 36

ASME SA 516 Gr 70 and SA 36 are carbon steel specifications under ASME standards, but they serve different purposes: SA 516 Gr 70 is a normalized pressure vessel steel with high strength for boilers and tanks, while SA 36 is a structural steel (equivalent to ASTM A36) for general construction like bridges and buildings. SA 516 Gr 70 offers better toughness and higher tensile strength, whereas SA 36 is more cost-effective for moderate-load applications. As a leading Chinese manufacturer and exporter, Gangsteel produces high-quality ASME SA 516 GR 70 plates for pressure vessels and asme sa 36 steel plate for structural uses, ensuring compliance with ASME standards.

Overview of ASME SA 516 Gr 70 and SA 36

ASME SA 516 Gr 70 is a carbon-manganese steel normalized for improved notch toughness in low-temperature pressure vessels. ASME SA 36 is a carbon steel used for welded structures with good ductility but no heat treatment required. Gangsteel's ASME SA 516 GR 70 is ideal for high-pressure applications, while our asme sa 36 steel plate suits general construction, complementing grades like ASME SA 516 GR 60 and ASTM A 516 GR 70.

The table below summarizes key specifications:

Chemical Composition Comparison

SA 516 Gr 70 has lower carbon and higher manganese for better toughness, while SA 36 allows higher carbon for strength. Below is a table of typical compositions (in weight %, maximum unless specified):

Gangsteel's ASME SA 516 GR 70 and asme sa 36 steel plate adhere to these for optimal performance.

Mechanical Properties Comparison

SA 516 Gr 70 has higher yield and tensile strength than SA 36, making it suitable for pressure applications. The table below details typical values:

Gangsteel's plates, including ASTM A 516 GR 70 and astm a 36 steel plate, meet these requirements.

Applications and Interchangeability

SA 516 Gr 70 is used in high-pressure boilers and vessels, while SA 36 is for general structures like bridges. They are not interchangeable due to strength and treatment differences. Gangsteel's plates support both with certifications.

FAQ

• What is the main difference between SA 516 Gr 70 and SA 36?SA 516 Gr 70 has higher strength (70 ksi tensile) for vessels, SA 36 (58 ksi) for structures.
• Is SA 516 Gr 70 normalized?Yes, for better toughness; SA 36 is as-rolled.
• What is the yield strength of SA 516 Gr 70?Minimum 38 ksi (260 MPa), higher than SA 36's 36 ksi.
• Can SA 36 replace SA 516 Gr 70?No, due to lower strength and lack of normalization for pressure use.
• Where can I buy SA 516 Gr 70 or SA 36 plates?Gangsteel offers compliant plates; contact for ASME SA 516 GR 70 or asme sa 36 steel plate.
