ASTM A515 is a pressure vessel steel specification that covers carbon and low alloy steel plates. It is primarily used for welded boilers and pressure vessels operating at medium and high temperatures. The steel has an optimized chemical composition with manganese, phosphorus, sulfur and vanadium added to increase strength. It has good weldability and can be welded by manual, automatic or forge welding methods. Typical applications for A515 steel include boilers, pressure vessels, heat exchangers, piping, and turbine casings. It is commonly used in the petroleum, chemical, power generation and process industries where high temperature service is required.
A515 offers the best combination of high temperature strength, weldability and moderate cost for pressure vessel applications.

A515 Grade 55:This has a minimum yield strength of 55 ksi (379 MPa) and tensile strength of 75-90 ksi (517-620 MPa). It offers good weldability and heat treatment response.

A515 Grade 60: This grade has higher strength with a minimum yield of 60 ksi (414 MPa) and tensile strength of 80-100 ksi (550-690 MPa). It is the most common grade used.

A515 Grade 65: This grade has a yield strength of 65 ksi (448 MPa) min and tensile strength of 85-110 ksi (586-758 MPa). It provides even higher strength for demanding applications.

A515 Grade 70: This is the highest strength grade with minimum yield of 70 ksi (483 MPa) and tensile strength of 90-125 ksi (621-862 MPa). It is required for the highest pressure containment.
