ASTM A193 Grade B8M Bolts and Studs
ASME SA 193 B8m Class 2 Bolts, A193 gr b8m stud material Manufacturer in India
There is 18% chromium, 8% nickel and up to 4% molybdenum in the composition of the ASTM A193 Grade B8m Threaded Rod and it provides the material with high strength, corrosion resistance and required toughness. The prices of the fasteners are comparatively lower. The ASTM A193 B8m Nut comes with a 515MPa minimum tensile strength and 205Mpa minimum yield strength. There are carbon, manganese, sulfur and silicon present in the material in smaller quantities as well. The ASTM A193 B8m Class 1 Bolts have slightly lower mechanical properties than the class 2 fasteners and are cheaper. There are different thread types to the fasteners such as fine and coarse threads. The A193 Gr B8m Material can be used to produce any type of thread and the different sizes of the fasteners based on the standards. The applications of these corrosion resistant ASME SA193 Grade B8m fasteners can be seen in sea water, marine, ship building and other corrosive applications. There are general corrosive applications and food grade applications that use these fasteners as well. There are super duplex and other alloy SA 193 Gr B8 Equivalent materials as well. Regal Sales Corporation is a leading manufacturer and supplier of the different types of ASTM A193 Grade B8M Bolts in various dimensions. Please feel free to contact us for any details such as the Sa 193 B8 Yield Strength, pricing, dimensions or a full product catalog.

ASTM A193 B8m Class 2 Bolts and class 1 bolts are made from the 316 austenitic stainless steel material. The dimensions of the bolts are governed by the ASME B18.2.1 and B18.3 standards. There are class 1 and class 2 bolts under this specification. The fasteners such as the B8M Stud are corrosion resistant to chloride ion stress corrosion cracking due to the molybdenum addition in the composition.
