– Optimal hardness: The hardness range of 200-260 HB ensures the steel’s resistance to wear, abrasion, and indentation, contributing to its durability and longevity.
– High impact energy: The minimum impact energy of 27 Joules at -20°C ensures that 16NiCr11 steel can withstand sudden loads and external forces, making it suitable for construction in harsh environments.
3. Chemical Composition:
– Carbon (C): 0.14-0.20%
– Silicon (Si): 0.15-0.35%
– Manganese (Mn): 0.50-0.80%
– Nickel (Ni): 1.30-1.70%
– Chromium (Cr): 0.70-1.00%
– Sulfur (S): maximum 0.025%
– Phosphorus (P): maximum 0.035%
– Copper (Cu): maximum 0.30%
The chemical composition of 16NiCr11 steel ensures the desired combination of strength, hardness, and toughness necessary for construction purposes. The presence of nickel and chromium contributes to the steel’s high tensile strength and resistance to corrosion. Additionally, controlled levels of carbon, silicon, manganese, sulfur, phosphorus, and copper enhance the steel’s machinability, formability, and weldability.
Overall, 16NiCr11 steel is an excellent material choice for building reliable structures in the construction industry, offering a balance of mechanical properties and chemical composition that fulfill the stringent requirements of durability, strength, and integrity.
