What is ASTM A193 BB8m Bolts

B8M Stud

B8M Stud

ASTM A193 Grade B8M bolts are made from a more corrosion-resistant type 316 stainless steel. ASTM A193 B8m Class 2 Bolts are widely used in various industries like automobile and mechanical. ASTM A193 B8m Nut have high-temperature, high-pressure performance of these bolts and nuts make them suitable for applications in process industries, such as chemicals and petroleum where they are widely used in pressure vessels.

Both 304 & 316 grades are common grades of austenitic stainless steel used in the production of fasteners and are easily available in the markets. The alloy of grade 316 stainless steel primarily constitutes of elements like chromium, nickel and molybdenum. All of these metals are responsible for the enhanced characteristics of the B8M Stud & ASTM A193 B8M Bolts. Another feature of the A193 Gr B8m Material is its good performance in terms of its strength at elevated temperatures.

In comparison to grade 304, Type 316 stainless steel offers superior corrosion resistance due to the added molybdenum in its alloy. Because of the excellent corrosion resistance of the A193 Gr B8m Material fasteners made from 316 grade stainless steel in marine, seawater or brine environments, these fasteners are known as Marine grade stainless steel.

A193 B8m fasteners are available in two classes - A193 Gr B8m Material Class 1 fasteners are required to undergo carbide solution treatment, otherwise known as solution annealing.A193 B8m Class 2 Bolts fasteners are required to be processed by getting an additional strain hardening operation. This strain hardening operation will increase the tensile strength of the A193 B8m Stud Bolts alloy. Apart from an increase in the tensile strength, the hardening process aids in reducing the B8M Stud & A193 B8m Class 2 fasteners from being susceptible to galling.

Another point to distinguish both these classes is that the ASTM A193 Gr B8m Studs Class 2 fasteners are marked as B8MSH with the grade symbol being underlined.The Grade B8m Bolts specification is heavily utilized in industries like petroleum as well as in chemical and construction applications.
