Alloy A193 B7 A194 2H Washers high tensile alloy steel washers
ASTM A193 Grade B7 specification covers requirements for high tensile alloy steel bolting material for use in high temperature or high-pressure service and other special purpose applications.
ASTM A193 Grade B7 bolts and threaded studs are manufactured from a chromium-molybdenum steel and are quenched and tempered (heat treated) to develop the desired mechanical properties (strength). The ASTM standard covers alloy steel and stainless steel bolting materials for high temperature or high-pressure service. ASTM A193 B7 is a specification for medium-high temperature applications. It is a heat treated Chromium Molybdenum steel and is considered for applications up to 450¡ãC (840¡ãF). The ASTM A193 Grade B7 Washers is intended for higher temperature applications. Grade B7 bolts are tempered at a higher temperature, 1100¡ã F minimum.
