ASTM A193 Grade B8T Bolts

ASME SA193 B8T Stainless Steel Fasteners manufacturer in India


There are a variety of bolts with different grades available in the market. Ones made with austenitic steel display excellent mechanical strength as well as display resistance to corrosion. ASTM A193 Grade B8T Bolts work well in high temperature environment due to the grade of alloy that has been used in making it.

Conventional alloys display intergranular corrosion which is eliminated in B8T Fasteners. Due to this the creep and rupture properties of Stainless Steel ASTM A193 Grade B8T Plain Washer are higher as compared to bolts made up of conventional alloys.

Furthermore, Stainless Steel ASTM A193 Grade B8T Foundation Bolts display excellent mechanical properties when exposed to high temperatures. They are cold worked in order to harden the material and strengthen it. Since any sort of heat treatment does not cause the ASTM A193 Grade B8T Threaded Stud to harden.

These bolts are made up of an alloy that has titanium carbide which minimizes the intergranular corrosion in SS ASTM A193 Grade B8T Structural Bolts and stabilizes it. They are used in applications like non-metal flangs like PVC flanges, FRP flanges, and CPVC flanges. Furthermore, cryogenic applications also use these bolts. They are typically used in air-sep and related fields.

We at Siddhagiri Metal are one of the well-known manufacturers of ASTM A193 Grade B8T Fasteners. The bolts that we produce are well known for their sturdy body and seamless finish. The Grade B8T Stud Bolts supplied by us have outstanding forming and welding features. Stainless Steel ASTM A193 Grade B8T Hexagon Nut also resists pitting and crevice corrosion in a Chloride environment.
