Wanem samting bilong 1Cr5Mo steel plet? Sotpela pefomens bilong 1Cr5Mo
Wanpela.1 Wanpela Introdaksen bilong 1Cr5Mo
The metal tissue of 1Cr5Mo is martensite, with good oxidation resistance at around 650 degrees Celsius, good thermal strength below 600 degrees Celsius, and good shock absorption and thermal conductivity, which is widely used in steam turbines. But this kind of steel has a large hardening tendency, and the welding performance is poor.
