A516 Gr. 60/65/70 pressure vessel steel plates combine excellent strength and toughness with good weldability, making them the material of choice for medium- and low-temperature pressure equipment.
They offer stable weldability and are compatible with conventional low-carbon steel welding consumables. For thick plates, preheating to 80–150°C based on plate thickness effectively controls cold cracking, ensuring joint density and mechanical properties.
The material offers excellent machinability and supports various cutting methods, including flame, plasma, and laser cutting. It produces clean cut edges with a minimal heat-affected zone, meeting the precision manufacturing requirements for pressure vessels.
It exhibits outstanding cold forming properties; plates of standard thickness can be easily rolled and bent. With good plasticity and low susceptibility to cracking, it is suitable for forming components such as cylinders and heads.
The plates are uniformly shaped and subject to strict internal quality control. After normalizing or controlled rolling, internal stresses are balanced, and flatness and dimensional accuracy meet standards, ensuring high-quality alignment and assembly.
Mechanical properties are clearly graded: the tensile strengths for Gr. 60, 65, and 70 are 415–550 MPa, 450–585 MPa, and 485–620 MPa, respectively. With excellent low-temperature impact toughness, the material ensures safe and reliable long-term service.
Widely used in critical pressure-bearing components such as storage tanks, heat exchangers, boiler drums, and chemical reactors, this material balances safety and cost-effectiveness, making it a highly reliable solution for pressure vessels compliant with ASME standards.

What is A516 gr 60 material?
carbon steel plate
A516 Gr 60 is a carbon steel plate with a minimum yield strength of 32 ksi (220 MPa) and tensile strength of 60-80 ksi (415–550 MPa).
What is the difference between A516 grade 70 and grade 60?
60 has higher carbon content than A516 GR. 70 and has lower chromium content than A516 GR. 70; it is, therefore, less resistant to corrosion than A516 GR. 70 but still offers good resistance to oxidation when exposed to air at atmospheric pressure (approximately 14 psi).
What is the difference between A515 GR 60 and A516 GR 60?
A515 Grade 60 steel plate is primarily for intermediate- and higher-temperature service in welded boilers and other pressure vessels. A516 Grade 60 carbon steel plate grade is mainly utilized primarily in welded pressure vessels for moderate to lower temperature service.
What is the difference between A36 and A516 gr 60?
A36 has moderate strength and meets general structural requirements. A516 has higher strength and toughness, especially outstanding impact toughness, making it suitable for pressure-bearing and low-temperature environments.
What is the difference between A516 GR 70 and SA516 GR 70?
Both are used for pressure vessels and boilers, but ASME SA516 GR 70 is mandatory for ASME-coded projects, ensuring compliance with regulatory standards. ASTM A516 GR 70 is suitable for non-coded vessels or where ASME certification is not required.
What is the difference between A516 GR 70 and A572 GR 50?
A516 Gr. 70 is a pressure vessel steel, while A572 Gr. 50 is a high-strength structural steel. They are not interchangeable.
What is A516 GR 65 material?
GNEE's A516-65 and ASME SA516-65 steel plate products are made from carbon-manganese steels and produced to pressure vessel quality(PVQ) standards as delineated in ASTM A20/ASME SA20.
Is ASTM A516 Grade 60 or 70?
Applications of ASTM A516 GRADE 60 / 70 Steel Plate
Both grades are used in the fabrication of pressure vessels and Boilers, but due to its higher tensile strength and yield strength, Grade 70 is often preferred for applications requiring greater durability and strength.
What is the difference between ASTM A516 GR 70 and A36?
Tensile Strength: ASTM A516 GR 70 offers higher tensile strength (485–620 MPa) than A36 (400–550 MPa), making it better for high-pressure applications. Yield Strength: A516 GR 70's higher yield strength (260 MPa vs. 250 MPa) ensures greater structural integrity under pressure.
