scm420 hardenability

20MnCr5 - Ovako

20MnCr5 is a case-hardening steel with low carbon content but good hardenability reaching good wear resistance due to high surface hardness after hardening. The small grain size benefits in good ductility and fatigue strength. Suitable for gearboxes and axle gears. Ovako 236F is a standard variant with controlled sulphur content for consistent

Bearing Shaft Ju Feng Special Steel Co., Ltd.

SCM420 are alloy steel with high hardenability, temper brittleness, well weldability, less cold cracking tendency, good machinability, and great cold plastic strain. SCM420 generally are used for the parts which need high wear resistance, such as gears, shafts, Bearing Steels IspatGuruAug 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).
