Re: [MW:11721] difference on NUT/BOLT material

Dear Moin,

B7M is for high temperature service and for detail refer to
 A 193/A 193M Standard Specification for Alloy-Steel and Stainless Steel Bolting Materials for High-Temperature Service

L7M is for low temperature service and for detail refer to
A 320/A 320M Standard Specification for Alloy/Steel Bolting Materials for Low-Temperature Service

hope this can help you.

Regards,
Zarei
