ASTM A322 A322 E51L100 Introduce
The amount of chromium in the alloy gives it a high level of corrosion resistance, making it an ideal solution for applications such as food processing and marine environments. The nitrogen, nickel and manganese also help improve corrosion resistance as they act to reduce pitting and crevice corrosion. The machining of ASTM A322 A322 E51L100 is quite difficult due to its higher alloy content, meaning it requires machinability lubricants to make it easier. ASTM A322 A322 E51L100 should always be used in environments where the temperature can be controlled and it should not be exposed to acidic or alkaline solutions. It is also recommended that welding processes are performed using argon shielding and a special electrode is used.
