20CRMnNi Steel for Gears - Material engineering general

Jan 16, 2006 · The chemical composition that you provided equates to grade 20CrMn according to the Chinese standard GB 3077. There is no 20CrMnNi designation. As lgearhart and Flesh have pointed out, there are other factors to consider when determining the proper steel grade, such as core hardness/strength, toughness, etc. The equivalent Chinese grade to SAE 8620 is 20CrNiMo according to GB 3077. 20Cr2Ni4 equvalent-C H I D STEEL GRADE - Shipbuilding For more information about GB/T 3077 Alloy steel plate,please clicking Mill Technical Information .If GB/T 3077 27SiMn covers steel bar 250mm 20CrNiMo Steel Chemical composition,Metal Properties 20CrNiMo.China GBT 20CrNiMo China structural steel and alloy steel and 20CrNiMo Mechanical Properties,Chemical Element,Cross Reference
