EN30B Chemical Composition

The Chemical Composition of EN30B contains a  low carbon content of 0.26 - 0.34 %. The material has an Mn content of 0.5 - 0.6 % which is also relatively low. The contents of P is reduced to 0.05% and S is reduced to 0.05 % max as excess content of P and S can damage the quality of steel and can cause the alloys steel to break at low stresses. There is a high Chromium content of 1.1-1.4 % which adds additional yield and tensile on heat treatment. The high Nickel content of 3.90%-4.30% is present which imparts a ductile core and high heat treatment temperature capabilities.

EN30B APPLICATION

Hardness is a major factor in the selection of EN30B for the manufacture of high-end machine parts. Chemical manufacturing, shipbuilding, and the oil and gas industry use EN30B extensively. The alloy content of EN30B provides high tensile strength. For the processing of EN30B, high temperatures can be used. EN30B can also be used to make machine parts such as screws, machine arms, pistons, shafts, and axles. Often, EN30B is used in products that undergo continuous wear and tear.
