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
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).

Product Introduction SCM420 alloy structural steel has high hardenability, no tempering brittleness, good weldability, little cold crack forming tendency, good machinability and cold strain plasticity. Chemical Composition Mechanical Property Heat Treatment Product Application SCM420 in Effects of Microalloying on the Impact Toughness of 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)).
mass-produce the TM steel, high hardenability which results from microalloying of Cr, Mo, and/or Ni should be required because the lack of hardenability of steel The matrix structures of the steels B through E and the SCM420 steel comprised phases of varying image qualities (IQs).
