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
Aug 06, 2020 · SCM420 and 20MnCr5 are Japanese and German grades respectively, found in carburized bearing components. In addition to standard AISI grades, bearing steels can also be designed so that their hardenability matches the requirements of specific section thicknesses.

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).

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
Jul 20, 2013 · In SCM420 steel, a large number of voids originated in the wide lath-martensite structure, and these decreased the deformability of the steel owing to the increase in the volume fraction of the carbide (Figures 10(c) and (d)).
