COLD ROLLED/COLD DRAWN STEEL PIPE
s10c s20c s45c cold drawn steel tube for machining purpose
Mechanical tube Standard: JIS G3445 Application: It is widely used in manufacturing of Machinery, Automobile, bycycle, furniture and some other machined parts. Steel Tube Grade: STKM 11A, STKM12(A,BC),STKM13(A,B,C),STKM14(A,B,C) Chemical Composition
42CrMo4 precision seamless steel tube for auto parts chemical composition: Carbon C 0.38～0.45% Silicon Si 0.17～0.37% Manganese Mn 0.50～0.80% Sulfur S Allow residual content ≤0.035% Phosphorus P allowable residual content ≤0.035% Chromium Cr 0.90～1.20% Nickel Ni allowable residual content ≤0.30% Copper Cu allowable residual content ≤0.30% Mo 0.15～0.25% Mechanical properties: Hardness: Annealing, 255～207HB, indentation diameter 3.8～4.2mm; Quenching, ≥60HRC cr12mov The hardenability, hardness, strength and toughness after quenching and tempering are higher than CR12, and the work with a diameter of 300-400mm or less can be completed Hardenable, small quenching deformation, but poor high temperature plasticity. cr12mov plates are mostly used to manufacture composite molds and tools with large cross-sections, complex shapes and heavy workloads.
