A515 Pressure Vessel Steel Plate

ASTM A515 is the same as ASME SA-515 and is the standard specification for welding carbon steel pressure vessel plates for high temperature service in boilers and other pressure vessels.


A515/SA-515 plate can be divided into 3 grades according to its minimum tensile strength: grade 60, grade 65 and grade 70. SA515 is a carbon sulfide steel plate for high-temperature pressure vessels that complies with ASTM A515/A515M standards. It has high strength and corrosion resistance and is suitable for manufacturing pressure vessels working in medium to high temperature environments. When using SA515 steel plate to manufacture pressure vessels, welding and heat treatment must be carried out in accordance with relevant standards and requirements to ensure the safety, reliability and durability of the vessel.
