The specification of X15CrNiSi2012 steel includes its mechanical properties and chemical composition, which are essential factors in ensuring sustainable manufacturing practices.

Mechanical Properties:
– Tensile Strength: The steel should have a minimum tensile strength of 550 MPa, indicating its ability to withstand pulling or stretching forces without breaking.
– Yield Strength: The yield strength of the steel should be at least 450 MPa, which means it can resist deformation under applied forces.
– Elongation: The steel should have a minimum elongation of 20%, indicating its ability to stretch and absorb energy before breaking.
– Impact Resistance: The steel should have good impact resistance, ensuring it can withstand sudden shock or dynamic loading without failure.
– Hardness: X15CrNiSi2012 steel should have a hardness between HRC 20-25, indicating its ability to resist deformation and wear.

Chemical Composition:
– Carbon (C): Carbon content in X15CrNiSi2012 steel should be between 0.15-0.20%, providing the required strength and hardness.
– Chromium (Cr): Chromium content should be between 16.0-18.0%, which helps in creating a corrosion-resistant layer on the surface of the steel, enhancing its durability.
– Nickel (Ni): Nickel content should be between 1.0-3.0%, which improves the steel’s strength, ductility, and resistance to corrosion.
– Silicon (Si): Silicon content should be between 1.0-3.0%, aiding in deoxidization and improving the steel’s strength and resistance to heat.
– Manganese (Mn): Manganese content should be between 6.0-8.0%, which contributes to the steel’s strength, hardenability, and weldability.
– Phosphorus (P) and Sulfur (S): These elements should be kept at low levels to ensure better machinability and avoid brittleness in the steel.

Overall, the mechanical properties and chemical composition of X15CrNiSi2012 steel should meet stringent standards to ensure its suitability for sustainable manufacturing practices.
