Volume 4D is a practical guide to heat treating irons and steels, and is particularly helpful in the context of selecting materials and determining part geometries and process plans. 3. Heat treating steel, which involves intense heating followed by cooling, alters the physical and sometimes chemical properties of steel, which thereby impact the material’s mechanical properties. The carbide solution treatment of stainless steel fasteners can improve cryogenic or low temperature toughness and is part of the ASTM A320 specification. Carbides may form during heating in the 425 to 900°C (800 to 1650°F) range or during slow cooling through this range. But unlike other metals, the end of the casting process does not necessarily mean the product or component is market-ready.
