About ASTM A193 Grade B8 Class 2 Hex Bolt
ASTM A193 Grade B8 Class 2 Hex Bolts are premium high-tensile, corrosion-resistant fasteners manufactured from strain-hardened AISI 304 austenitic stainless steel. They are explicitly designed for high-pressure, high-temperature, and severe chemical process environments including pressure vessels, valves, flanges, and piping systems.

Key Product Features
- Elevated Tensile Performance: Unlike standard Class 1 bolts that only manage a baseline tensile rating of 75 ksi, Class 2 bolts leverage intense strain-hardening to deliver a robust 125 ksi tensile capacity.
- Severe Environment Longevity: The targeted addition of Chromium and Nickel guarantees reliable defense against atmospheric corrosion, localized pitting, and moisture degradation.
- Anti-Galling Homogeneity: Undergoes solution annealing temperatures between 1,100C to 1,200C to securely resolve chromium carbides within the crystal matrix.
Core Technical Applications
These heavy-duty fasteners are heavily utilized inside specialized heavy industries:
- High-pressure oil and gas piping connections.
- Chemical and petrochemical processing refineries.
- Marine offshore drilling platform equipment.
- Food and beverage manufacturing facilities.
