20CrMo alloy steel plates are generally used in quenching and tempering or carburizing state.20CrMo steel are used in the manufacture of high pressure tubes and various fasteners and more advanced carburizing parts,such as gear and shaft,working in the medium of non corrosive medium and working temperature below 250 and containing nitrogen and hydrogen mixture.38CrMoAl Alloy Structure Steel (Nitride Steel)- BBNSTEEL Jan 19,2021·38CrMoAl is an alloy structural steel characterized by high aluminum composition,which is generally used after quenching and nitriding.After nitriding,38CrMoAl has high surface hardness,wear resistance and fatigue strength,and has [BBNSTEEL STAINLESS]good heat resistance and corrosion. STANDARD GB/T 3077 SAE 6470 JIS G4053 DIN EN 10085 GRADE 40Cr Steel CNC Machining Parts CNC Mechanical Steel CNC Machining 40Cr Steel Parts.40Cr Steel Is The Standard Steel Grade Of GB In Our Country,And 40Cr Steel Is One Of The Most Widely Used Steels In Machinery Manufacturing Industry.After Quenching And Tempering,It Has Good Comprehensive Mechanical Properties,Good Low Temperature Impact Toughness And Low Notch Sensitivity.
The hardness of the steel can be increased if it has lower tempering temperature.For example,tensile strength of 225 ksi cab be achieved by tempering at 316°C (600°F),and a tensile strength of 130 ksi can be achieved by tempering at 538°C (1000°F).Hardening AISI 4140 alloy steel can be hardened by cold working,or heating and quenching.A brief inroduction of 40Cr alloy structual steel SHEW-E Jan 07,2019·Except quenching and tempering,40Cr is also suitable for nitriding and high-frequency quenching.The hardenability of 40Cr steel is good,which can be reached to 28 ~ 60mm in water quenching and 15 ~ 40mm in oil quenching.When 174 ~ 229HBS,the relative machinability is 60%.
