The chemical composition of 14NiCrMo134 steel typically consists of:
– Carbon (C): 0.10-0.17%
– Silicon (Si): 0.10-0.35%
– Manganese (Mn): 0.60-1.00%
– Nickel (Ni): 1.20-1.60%
– Chromium (Cr): 0.70-1.00%
– Molybdenum (Mo): 0.15-0.25%
– Phosphorus (P): max 0.035%
– Sulfur (S): max 0.035%
These alloying elements contribute to the mechanical properties of the steel, enhancing its strength and toughness. The steel is known to have good hardenability, meaning it can be hardened and tempered to obtain the desired properties.
The mechanical properties of 14NiCrMo134 steel include:
– Tensile strength: 980-1180 MPa
– Yield strength: 785-930 MPa
– Elongation at break: 13-16%
– Charpy impact strength: 25-35 J/cm²
These values may vary depending on the specific heat treatment applied to the steel. Heat treatment processes such as quenching and tempering can further improve the strength and toughness of the steel.
In conclusion, the 14NiCrMo134 steel grade is a low alloy steel with good strength and toughness properties. Its chemical composition and mechanical properties make it suitable for various applications that require high load-bearing capacity and durability.
