We offer These ASTM A193 B8 CL2 Bolts as per DIN, ISO, JIS or ANSI Standard.
Corrosion Resistance: ASTM A193 B8 Class 2 bolts are made from 304 stainless steel, which provides excellent resistance to corrosion in various environments, including freshwater, industrial atmospheres, and mild chemical environments. This makes them suitable for outdoor and marine applications where exposure to moisture is a concern.
Temperature Resistance: These bolts maintain their mechanical properties at a wide range of temperatures, making them suitable for use in both high and low-temperature applications. This includes cryogenic applications where the temperature can drop significantly.
Strength and Durability: ASTM A193 B8 Class 2 bolts are designed to provide high tensile strength and good toughness, ensuring they can withstand heavy loads and mechanical stresses without deforming or breaking easily.
Ease of Fabrication: They are relatively easy to machine, which facilitates their use in manufacturing processes where custom sizes or shapes are required. This ease of fabrication also reduces production time and costs.
Widely Accepted Standards: ASTM A193 is a globally recognized specification for alloy steel and stainless steel bolts used in high-temperature or high-pressure service. Using bolts that meet this standard ensures compliance with industry requirements and specifications.
ASTM A193 B8 CL2 Bolts applications are as diverse as the industries they serve driven primarily by the aerospace, railway, construction and automotive industries with petrochemical, nuclear, medical, Oil & Gas, Chemical, Pharmaceutical, Food & Beverage, Nuclear, Thermal Power plants, Paper and Pulp, marine and mining, etc.
