A516 Grade 70 boiler steel plates are mainly used in welded pressure vessels where improved notch toughness is important.Generally As rolled is ok for rolling pressure vessel steel plate A516Gr70, however, for improve steel property and toughness,Katalor engineers suggest the end users accept rolling A516 Grade 70 steel plates under Normalized,especially for the steel plates thickness above 40mm.NACE MR-0175 A516 Grade 70 also offered by Katalor with HIC test and SSCC test.

ASTM A516 Gr 70 /ASME SA516 Gr 70 is an excellent choice for service in lower than ambient temperature applications, has excellent notch toughness and is used in both pressure vessels and industrial boilers.ASTM A516 Gr 70/ ASME SA516 Grade 70 offers greater tensile and yield strength when compared to ASTM A 516 Gr65 /ASME SA516 Gr65 and can operate in even lower temperature service.

A 516 Grade 70 boiler steel usual request normalized if thickness above 40mm, if not , Katalor usual delivery in hot rolled or control rolled station. A 516 Gr.70+N or A516gr70N mean that steel grade must be normalized in any thickness.
