,09CUPCRNI-B steel manufacturer. stock increased rapidly. The social stock of five kinds of steel products (screw steel, wire rod, hot rolled coil, cold rolled coil and medium and heavy plate) in major cities in China was 8.12 million tons at the end of January and 19.05 million tons at the end of February. By the middle of March, the social inventory was 20 million tons, an increase of 13.18 million tons or 193.3% over the end of December last year.42CrMo steel plate is an ultra-high strength steel plate, which is widely used in machinery manufacturing steel. The steel is suitable for manufacturing large and medium-sized plastic molds that require certain strength and toughness. 42CrMo steel has high strength and toughness, good hardenability, no obvious temper brittleness, high fatigue limit and multiple impact resistance after quenching and tempering, and good low temperature impact toughness.A514 gr.A steel coil chemical composition (melting analysis)%C: 0.15-0.21, Si: 0.40-0.80, Mn: 0.80-1.10, P max.: 0.035, S max.: 0.035, B max.: 0.0025, Cr: 0.50-0.80, Mo: 0.18-0.28, Zr: 0.05-0.15The mechanical properties in thickness (mm)T≤65Yield strength (≥Mpa): 690Tensile strength (Mpa):760-895Elongation in ≥,%: 18After sales service support personnel pay attention to commitment in their work.
