SK5 steel strip characteristics and chemical composition


SK5 steel strip characteristics and chemical composition

    SK5 steel strip is a steel strip made of SK5 steel . SK5 steel has excellent comprehensive properties, such as mechanical properties (especially elastic limit, strength limit, yield ratio) and anti-ballistic performance (ie, anti-elasticity reduction performance, Also known as anti-relaxation properties), fatigue properties, hardenability, physical and chemical properties (heat resistance, low temperature resistance, oxidation resistance, corrosion resistance, etc.). Today, Xiaobian will tell you about the characteristics and chemical composition of SK5 steel strip .

Characteristics and scope of application: High hardness and wear resistance after quenching and tempering, but low thermosetting, poor hardenability, easy deformation, low plasticity and strength. Used as a tool that requires high hardness and wear resistance, such as simple molds and punches, metal cutting tools, wood cross boring tools, industrial milling cutters, countersunk drills, hand saw blades, axes, stones Chisel, longitudinal hand saws, and fitter assembly tools, rivet dies, etc.

Chemical composition : carbon ( C ), 0.80-0.90 , manganese ( Mn ), 0.10-0.50 , silicon ( Si ), 0.10-0.35 sulfur ( S ), ≤0.030 , phosphorus P , ≤0.030 , chromium ( Cr ), allowing residue Content ≤ 0.25, ≤ 0.10 (when manufacturing lead bath quenched steel wire) , nickel ( Ni ), allowable residual content ≤ 0.20, ≤ 0.12 (when manufacturing lead bath quenched steel wire) , copper ( Cu ), allowable residual content ≤ 0.30, ≤ 0.20 (When manufacturing lead bath quenched steel wire) . Note: Allow residual content Cr+Ni+Cu≤0.40 (when manufacturing lead bath quenched steel wire) .
