Alternative to Ni-bearing carburizing steels and new grades for high temperature carburizing (assimilated to 20MnCr5) steel on fatigue resistance, from  Bild 4. The standard
20MnCr5 carburized shaft is fai led in premature ductile intergranular mechanism . 18CrNi8 steel is pack carburized at 925 0 C of 3 to 12 hrs. The total case depth is found 1.06 times the 13. BEARING MATERIALSchrome molybdenum steel, etc. are often used. Such steels, when they are carburized to the proper depth and have sufficient surface hardness, are more shock resistant than normal, through-hardened bearing steels because of the softer energy-absorbing core. The chemical composition of common carburized bearing steels is listed in Table 13.2. 13
Percentage of Elements in Chemical Composition of grade 16MnCr5 steel (1.7131):EN 10084-2008 Elements not quoted in this table shall not be intentionally added to the steel without the agreement of the purchaser, other than for the purpose of finishing the heat. 20MnCr5 - OvakoSteel grade Last revised:Thu, 05 Nov 2020 10:52:40 GMT 20MnCr5 All General Information 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
20MnCr5 is structural alloy steel with great strength, toughness and hardenability. After heat treatment, 20MnCr5 material properties are better than 20Cr. Negligible quenching deformation, good low-temperature toughness. The machinability is good, but the welding property not as well. 20MnCr5 steel material usually is used at the state that after hardening and tempering or carburizing 20MnCr5 Steel 1.7147 case-hardened steel - Special steel 20MnCr5 gearing steel is DIN standard Alloy Carburizing gearing steel, 20MnCr5 gearing steel properties is a chromium, manganese, titanium alloy steel specification. it is equivalent with GB 20CrMn standard Carburizing steel, gearing steel.
