ASTM A515 Grade 60 boiler steel plate under A515/A515M steel standard specification for pressure vessel steel plate,carbon steel for intermediate and higher temperature service.Generally as rolled for boiler steel plate SA515 Grade 60 shall be ok,for thickness above 40mm,Yusheng steel suggest customers accept Normalised heat treatment for pressure vessel steel plate A515 Grade 60 which can improve the steel property and enhance steel toughness.

 

Pressure vessel steel plate A515 Grade 65 is under ASTM A515/A515M steel standard,there are other two relative steel grades in this standard,A515 Grade 60 boiler steel and A515 Grade 70 boiler steel.Comparing with A515 Grade 60,boiler steel plate A515 Grade 65 owned a higher contains in element Carbon,so boiler steel plate A515Gr65 has a higher yield strength and tensile strength after rolled. The steel A515 Grade 65 shall be killed and made to a coarse austenitic grain size practice.

 

ASME SA515 Grade 70 and ASTM A515 Grade 70 are carbon silicon steel plate for building boilers and pressure vessels in intermediate and higher temperature services.There are three steel grades A515 Grade 60 boiler steel plate,A515 Grade 65 boiler steel plate and A515 Grade 70 boiler steel plate owning to different yield strength and tensile strength.Pressure vessel steel plate A515Gr70 owned tensile strength within 485-620 Mpa,and the minimum yield strength shall be above 260 Mpa.The steel grade A515 Grade 70 contains a higher carbon contains comparing with A515 Grade 60 and A515 Grade 65.
