Chemical composition:

The chemical composition of 14MoV63 steel grade typically includes the following elements:

– Carbon (C): 0.10-0.18%
– Silicon (Si): 0.10-0.35%
– Manganese (Mn): 0.70-1.10%
– Phosphorus (P): 0.025% maximum
– Sulfur (S): 0.010% maximum
– Chromium (Cr): 0.30-0.70%
– Molybdenum (Mo): 0.40-0.60%
– Vanadium (V): 0.05-0.10%
– Niobium (Nb): 0.005-0.050%
