What is ASTM A193 B7?

ASTM A193 Grade B7 is a standard material specification for chromium-molybdenum alloy steel fasteners for use in high tensile, high temperature and special purpose applications.

Is ASTM A193 Grade B8 stainless steel?

ASTM A193 Grade B8 Class 1 bolts and threaded studs are manufactured from AISI 304 stainless steel. A193 Grade B8 Class 2 bolts are strain hardened after carbide solution treatment to achieve increased strength characteristics and reduce the potential for galling.

What is the difference between ASTM A193 and ASTM A320?

The only difference between the two bolts is intended application. A193 bolts are intended for high temperature and high pressure applications, while A320 bolts are for cold temperature applications.

What is A193 Grade B8?

ASTM A193 Grade B8M is a standard material specification for high tensile 316/316L stainless steel bolts, screws, studs or other external threaded fasteners for high-temperature, high-pressure service and other special purpose applications. Grade B8M fasteners are used for high strength pipeline bolting applications.
