ASTM A193 B8 Cl 2 Fasteners Supplier

Neelkamal Fasteners is one of the important manufacturing and supplying companies of ASTM A193 B8 CL2 Fasteners to worldwide customers. Our manufacturing team always delivers good quality products to clients. We supply these fasteners throughout the world. These fasteners are available in various grades and particular thicknesses.

Description of ASTM A193 B8 CL2 Fasteners:

ASTM A193 Grade B8 Class 2 specification covers requirements for stainless steel material with high tensile properties for use in high temperature or the high-pressure service and other purpose applications. It is a carbide solution that strains hardened stainless steel bolting material with higher tensile strength and excellent hardness. These class 2 fasteners are used for bolting pipeline flanges and other equipment intended for high-temperature or high-pressure applications. These Fasteners are manufactured using this mild stainless steel that needs carbide solution treatment on bars to be threaded or after the heading operation for the bolts with forged heads. 

The Carbide solution treatment is also referred to as solution annealing. It is a process in which the fasteners are heated and then water-quenched to confirm high corrosion resistance. This ASTM A193 B8 CL2 fastener material specification defines the typical chemical composition, product marking, certification, hardness requirement, mechanical properties, preferential heat treatment, and other requirements suitable for bolting used in pressure vessel service, valves, flanges, etc. fittings. 

Composition of ASTM A193 B8 CL2 Fasteners

  • Carbon
  • Manganese
  • Phosphorus 
  • Sulfur
  • Silicon
  • Chromium
  • Nickel 

Best properties of ASTM A193 B8 CL2 Fasteners

These Fasteners have mechanical properties such as tensile strength, yield strength, hardness requirement. In addition, it has good corrosion properties inherited from the austenitic nature of the alloy. 

These CL2 grades cannot be hardened by thermal treatment. Cold working provides enhanced levels of tensile strength. All austenitic stainless steel fasteners are generally non-magnetic in the annealed condition.

  • Application Of ASTM A193 B8 CL2 Fasteners

It is used in seawater equipment, off-shore oil drilling companies, gas processing pharmaceuticals, heat exchangers, chemicals processing, petrochemicals, aircraft exhaust manifolds, power generation, and spiral welded tubes, burner pipes, and flues.
