A193 B8M Stainless Steel Thread Stud
A193 B8M Stainless Steel Thread Stud is a high-performance, corrosion-resistant fastener widely used in demanding industrial applications. Engineered under stringent standards, this stud is made from ASTM A193 Grade B8M material, a strain-hardened austenitic stainless steel type 316. Its excellent mechanical properties and resistance to chloride corrosion make it an essential component in industries like chemical processing, marine engineering, and power generation.
As a leading manufacturer and supplier, Flybear Fastener offers customized and precision-manufactured A193 B8M studs with guaranteed quality and fast delivery.
Product Overview
A193 B8M stainless steel thread studs are externally threaded fasteners used in high-temperature and high-pressure environments. Designed to fasten flanges, valves, and pressure vessels, they are available in various sizes and thread configurations. The Grade B8M distinguishes itself from B8 by using Type 316 stainless steel, which enhances its resistance to corrosion, particularly in chloride-rich and marine environments.

Material & Manufacturing Process
The A193 B8M stud is made from high-grade 316 stainless steel—a molybdenum-bearing alloy known for its strong resistance to pitting and crevice corrosion in chloride environments. This makes it far superior to 304 stainless steel in marine and chemical processing applications.
Manufacturing Process:
- Raw Material Inspection
- Cold Forming or Hot Forging
- Thread Rolling or Cutting
- Heat Treatment (Strain-Hardening)
- Surface Finishing (e.g., Passivation)
- Dimensional & Mechanical Testing
- Protective Packaging
This controlled process ensures the mechanical integrity and corrosion resistance of each stud we produce.
