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.
