The ASTM A182 standard specifies forged or rolled alloy and stainless steel materials for pipe flanges, forged fittings, valves, fasteners, and components for high-temperature service applications. Resistant Metal Alloys makes ASTM A182 forged bolts, nuts, studs, and other fasteners. Chemical composition, mechanical qualities, heat treatment, welding repairs, and other supplemental requirements for forged or rolled alloy and stainless steel materials used in pressure systems are covered by this specification.
