What is A193 B8M material?

What is A193 B8M material?

ASTM A193 Grade B8M Class 2 is a standard material specification for corrosion resistant 316 stainless steel fasteners such as bolts, screws, studs, threaded rods and other externally threaded parts, for use in high tensile, high temperature and special purpose applications such as pressure piping & pressure vessels …

What is the difference between B8 and B8M bolts?

These bolts have similar strength requirements but differ in their corrosion resistance. Grade B8 bolts are made from type 304 stainless steel, while Grade B8M bolts are made from a more corrosion-resistant type 316 stainless steel.

What is B8M?

ASTM A193/A193M-11 specifies the mechanical properties of bolts, screws and nuts made of austenitic (amongst others) stainless steels for high temperature or high pressure service and other special purpose applications.

Is A193 stainless steel?

ASTM A193 Grade B6 bolts and threaded rods are manufactured from AISI 410 stainless steel which has been quenched and tempered to increase strength. Because these bolts are manufactured from stainless steel, they are used in highly corrosive environments with elevated ambient temperatures.

What is ASTM A193 grade B8M Class 2?

ASTM A193 Grade B8M Class 2 is a standard material specification for corrosion resistant 316 stainless steel fasteners such as bolts, screws, studs, threaded rods and other externally threaded parts, for use in high tensile, high temperature and special purpose applications such as pressure piping & pressure…

What kind of strength does a ASTM A193 fastener have?

This is a cold working process which increases physical properties. 100,000-125,000 PSI Tensile Strength. ASTM A193 Grade B8M Class 2 Same as B8M except strain hardened, 90,000-125,000PSI Tensile Strength. ASTM A193 Grade BC 18-8 grade stainless with additional element of Columbium- same as type 347 type stainless steel.

Which is better A193 or B8M stainless steel?

A193 Grade B8M is chemically equivalent to AISI 316/316L stainless steel with improved strength, categorized in two different tensile classes namely class 1 and class 2.

What’s the difference between A193 grade B5 and B16?

Unlike the stainless steel grades within the A193 specification, Grade B16 has no corrosion-resistant properties unless they are coated. ASTM A193 Grade B5 bolts and threaded studs are manufactured from AISI 501 stainless steel which has been quenched and tempered to increase strength.
