ASTM A193 covers alloy steel and stainless steel bolting materials for high-temperature or high-pressure service, primarily used in pressure vessels, valves, flanges, and fittings. The most common grades we manufacture are B7 (Alloy Steel), B8 (SS 304), and B8M (SS 316).
SRG Fasteners rigorously tests all ASTM A193 components for precise mechanical properties to ensure safety in explosive and high-stress refinery environments.
