ASTM A193 B8 Bolts


What is ASTM A193 B8?

ASTM A193 Grade b8 bolts are high-tensile steel bolts used in industrial applications such as construction, chemical, and petroleum. This grade includes ASTM A193 B8 Fasteners in classes 1 and 2. Fasteners in class 1 are standard, whereas those in class 2 are hardened. When increased strength and hardness are required, class 2 is applied. ASTM A193 Gr B8 Class 1 Hex Bolts can be utilised in medium and high-temperature applications.
Different heat treatments are done to other classes of these fasteners, such as the SA193 B8 Flat Washers. The B8 is of superior quality, composed of AISI 209 steel that has been nitrogen strengthened. The Nitronic 50 grade is also known as A193 B8 Material.


SA193 B8 Stud Bolt vs A193 B8 Hex Bolts

The Hex Bolt A193 B8 is this grade's most often used fastener. Due to their high tensile strength values, the pins may be employed in high pressure, high tensile, and high-stress applications.

Before purchasing a193 b8 Hex bolts or stud bolts, see the a193 b8 bolt torque table and ASTM A193 B8 Bolts specifications. Our A193 b8 bolts are thoroughly inspected before shipment. Torsion, hardness, creep and drop weight tests on all ASME SA 193 B8 Stud bolts.


ASTM A193 Gr B8 Class 1 vs SA 193 B8 CL 2

There are two types of ASTM A193 B8 Studs. Class 1 fasteners are everyday studs, whereas class 2 fasteners are reinforced studs. The ASTM A193 B8 Nuts Class 2 material has been designed for use in situations that need a more robust metal. ASTM A193 B8 Stainless Steel Nuts uses, for example, include non-metal flanges.

The material and bolts are sturdy enough to endure extreme abrasions. Mechanical characteristics, hardness, and elongation differ between classes 1 and 2. Because of its strong corrosion resistance and hardness, A193 Gr B8 Bolts are utilised in petroleum and chemical applications. The mechanical qualities of the ASTM A193 B8 Heavy Hex Nuts class 2 are superior to class 1.
