Material Of Round Steel Wire
The material of round steel wire mainly includes carbon steel, stainless steel and alloy steel. Specifically, the material of round steel wire can choose different alloy compositions according to application requirements. For example, the main chemical composition of 82B coil round steel wire includes carbon content between 0.80%-0.85%, manganese content between 0.60%-0.90%, silicon content between 0.12%-0.32%, sulfur content ≤0.025%, phosphorus content ≤0.025%, and copper content ≤0.20%. In addition, the chemical composition of the round steel wire for wire thread inserts applied by Wuxi Wuda includes by weight percentage: 0.10-0.22% C, 10.0-13.5% Cr, 0.50-0.60% Si, 0.30-0.35% Mn, 0.15-0.25% Ni, 0.01-0.03% Mo, 0.15-0.20% Cu, 0.005-0.007% Ti, 0.001-0.002% S, 0.025-0.035% P, 0.001-0.002% Al, 0.085-0.090% V, 0.008-0.012% Co, 0.008-0.012% Nb, and the balance is Fe and unavoidable impurities.
The selection of these materials and the design of the composition ratio are designed to meet the performance requirements of round steel wire in different applications. For example, 82B coiled round steel wire has high strength and good toughness, and is suitable for applications with high strength requirements, such as manufacturing prestressed steel wire and steel strands. Wuxi Wuda's round steel wire for wire thread inserts has improved strength, wear resistance and fatigue resistance through specific chemical composition and quenching process.
