Product Information

SA516 Grade 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.

A516 Grade 70 offers greater tensile and yield strength when compared to ASTM A516 Grade 65 and can operate in even lower temperature service.

Our plates come with mill certification in accordance with ASTM or ASME. Our plates are fully traceable, usually with hard stamping and we welcome any third party or customer inspection if required which can be arranged with the client.

Available size range

Thickness:6mm-120mm
Width:1500mm-4020mm
Length:3000mm-27000mm
