ASTM A193 B8M Bolts

The grade B8M or in this case the ASTM A193 B8M Bolts are manufactured from austenitic stainless steel alloy 316. Per the specification, the astm a193 grade b8m threaded rod is designed to withstand not only high temperature, but also high pressure settings.

Which is why A193 B8M Material is used in the manufacture of fasteners like bolts to cater to the needs of industries, where the applications are based in high pressure and/or high temperature conditions. Since the ASTM A193 Gr B8m Studs adhere to the chemistry requirements of the specification, no additional element must be added to the alloy of these steel grades. The tensile property or the B8M Yield Strength along with hardness property requirements have been discussed in the specification.

 

The specified A193 B8M Heavy Hex Bolts could be categorized into two classes i.e. – Class 1 and Class 2. They are categorised based on the treatment these ASME SA193 B8M Nuts undergo. Hence, ASTM A193 B8m Class 1 are bolts produced from grade 316 stainless steel that have been carbide solution treated. On the other hand, astm a193 b8m class 2 bolts, similar to class 1 have been produced from marine grade 316 stainless steel and have been treated to a carbide solution process. The only difference between class 1 and class 2 is that a class 2 ASTM A193 Gr b8m bolt has also been strain hardened. Click here to view details from the A193 B8M Bolt Torque Chart.
