CK20 Stainless Steel Properties, Composition & Equivalent
CK20 ASTM A743 A351 Grade(UNS): J94202 Alloy Family: Austenitic Stainless Steel Equivalent: 310 stainless steel
What is CK20 Stainless Steel ?
CK20 is a kind of soft austenitic steel alloy has high oxidation resistance. Which is used in sulfite solution and dilute sulfuric acid at room temperature.
This kind of stainless steel has high strength, less quenching and no temper embrittlement. It can be used in parts with low stress and high toughness requirements.
CK20 stainless steel alloy is generally used in mechanical parts and automobile manufacturing to produce parts with high surface requirements and low center requirements
