Alloy structural steel 30CrNiMo8

Alloy structural steel 30CrNiMo8 is a European standard steel grade. 30CrNiMo8 steel plate has high yield strength, tensile strength and fatigue strength, as well as sufficient plasticity and toughness. 30CrNiMo8 is quenched and tempered steel equivalent to 30Cr2Ni2Mo in China.

Chemical composition of 30CrNiMo8 steel plate:
C: 0.26-0.34, Si: max 0.4, Mn: 0.5-0.8, Ni: 1.8-2.2, P: max 0.025, S: max 0.035, Cr: 1.8-2.2, Mo: 0.3-0.5.

Alloy structural steel 30CrNiMo8 delivery status: generally delivered in annealed state, the specific delivery status should be indicated in the MTC.

30CrNiMo8 steel plates are generally smelted in electric arc furnaces and oxygen top-blown converters, and those with high requirements are refining outside the furnace, electroslag remelting or vacuum treatment, vacuum induction furnace smelting or double vacuum smelting, and suitable heat treatment.
