ASTM 4130 Alloy Steel Castings OEM Investment Castings

The total alloy content can range from 2.07% to approximately 10.5%. For many low-alloy steels, the primary function of the alloying elements is to increase hardenability (the degree to which the steel will harden during heat treatment). Alloy additions can also be used to reduce environmental degradations under certain specified service

    N22CB hardenability correspond to intermediate between S20C and SCM420(Fig.1).2.Carburizing Hardenability
    N22CB carburizing hardenability is a little bit inferior than SCM420. however it can get the same carburized case depth as S20C in half time.(Fig.2) Notice)Carburizing is liquid carburizing, and 180 salt quenching.3.N22CB hardened & tempered material's tensile property
    Hardened and tempered N22CB has excellent toghness which shows about 10% elongation even without tempering.(Fig.3). Notice) 1)Test piece is JIS No.5, direction of extraction is L,thickness is 2.6mm 2)Quenching condition is 900-15min W.Q. 3)Tempering time is 30minTECHNICAL DATA COMPARISON OF MATERIALS snc236 snc415 snc631 snc815 snc836 sncm220 sncm240 sncm415 sncm420 sncm431 sncm439 sncm447 sncm616 sncm625 sncm630 sncm815 scr415 scr420 scr430 scr435 scr440 scr445 scm415 scm418 scm420 scm421 scm430 scm432 scm435 scm440 scm445 scm822 i a i s i b s 970 part1,3 bs en 10083-1,2 din en 10084 nf a35-551 4543 nf en 10083-1,2 din en 10083-1,2 sae 683

    Case Hardening Steel Scm 420, for Construction, Popular

    Product Description. SCM420 steels is used to make all kinds of fasteners, high pressure pipe and more advanced carburized parts, such as gear, shaft, etc.,which work in the noncorrosive medium and temperature below 250 , working with nitrogen hydrogen mixture in the medium. SCM420MO steels quench-hardening ability is higher, no temper Development of Carburizing Steel for Innovation in Parts represented by SCM420 in the JIS standard, has high hardenability. After hot rolling and cooling, the microstructure becomes ferrite and pearlite containing bainite. Since bainite is the hardest of these microstructures, preventing formation of bainite is effective for reducing deformation resistance. On the other hand, ferrite is the
