ASTM A193 Class 1 B8M All Thread Rods 316 Stainless Steel

ASTM A193 Class 1 B8M All Thread Rods – 316 Stainless Steel

Superior Corrosion Resistance for Critical Industrial Applications

ASTM A193 Class 1 B8M all thread rods, made from 316 stainless steel, are engineered for use in high-pressure, high-temperature, and corrosive environments. Commonly used in chemical processing, marine, pharmaceutical, and food-grade applications, these rods offer both mechanical strength and superior corrosion protection.

What Is ASTM A193 B8M Class 1?

The ASTM A193 standard covers stainless steel and alloy steel fasteners used in pressure vessels, flanges, valves, and piping systems. The B8M designation refers to fasteners made from 316 stainless steel, while Class 1 indicates strain-hardened material, which provides higher tensile strength than annealed stainless.

B8M Class 1 rods are fully threaded, making them ideal for flange bolting, pipe supports, and structural assemblies in environments exposed to chlorides, saltwater, and chemical agents.

Advantages of B8M Class 1 Threaded Rods

• ✅ Made from 316 stainless steel with molybdenum for enhanced corrosion resistance

• ✅ Strain-hardened to meet higher tensile and yield strength requirements

• ✅ Ideal for wet, acidic, or chloride-rich environments

• ✅ Conforms to ASTM A193 specifications for industrial pressure systems

• ✅ Compatible with B8M nuts and stainless washers for full system integrity

Applications and Availability

Available in standard diameters from 1/4" to 1-1/2" and up to 12-foot lengths, B8M threaded rods are widely used in:

• Coastal and marine construction

• Refineries and chemical processing

• Pharmaceutical and cleanroom environments

Choose B8M Class 1 for Maximum Corrosion Protection

For mission-critical fastening in the harshest environments, ASTM A193 B8M Class 1 all thread rods in 316 stainless steel deliver unmatched corrosion resistance and mechanical strength.
