Type 420 Stainless Steel provides both outstanding corrosion resistance and exceptional wear resistance. To obtain the best possible strength and wear resistance, oil quench alloy 420 at a temperature between 1800° F and 1950° F. Alloy 420 Stainless Steel is commonly used in dental and surgical instruments, cutlery, plastic molds, pump shafts, steel balls, and numerous hand tools. Because of its air hardening properties, type 420 Stainless Steel is not often welded, although, it is possible.
When welding with stainless steel type 420, preheat the steel to a temperature between 300° F and 400° F. After welding, temper the work piece at temperature for two hours. When hot working, it is recommended to gradually raise the temperature to 1400° F and then gradually raise the temperature to anywhere from 2000° F to 2200° F. While working, avoid letting the work temperature drop below 1600° F by frequently reheating the steel. To prevent cracking, furnace cool the work piece slowly after working. Any extreme cold forming will cause alloy 420 Stainless Steel to crack, but it can endure minor cold work.
