Hot rolled 09CuPCrNi-B steel properties size range

BBN company team and culture: tt the end of 2019, in order to thank employees for their hard work and enrich their sparetime lives, the company organized a pleasant trip to Phuket Island, Thailand. This tour lasted 6 days and 5 nights, and returned by plane on the evening of December 27. We took off in Zhengzhou at about 5o'clock in the afternoon on the 22th December. Let's seize the day and live it to the full, and greet the arrival of the year 2020 together.

The secondary quenching and low temperature tempering of wear resistant composite plate are mainly used for high alloy steel workpieces without mechanical processing after carburizing. Carburizing, high-temperature tempering, one-time heating quenching, low-temperature tempering, quenching temperature 840-860℃, mainly used for Cr Ni alloy carburizing workpiece. The second quenching and low-temperature tempering of wear-resistant composite plate, 09CUPCRNI-B steel properties mainly improves the microstructure of the infiltrated layer. When the requirements for core properties are not high, quenching can be performed between AC1 and AC3, and when the requirements for core properties are high, it should be quenched above AC3.

Mechanical properties of 45# steel high-quality carbon structural steel: Tensile strength σb (MPa): ≥600, yield strength σs (MPa): ≥355, elongation δ5 (%): ≥16, section shrinkage ψ (%): ≥40, impact energy Akv (J): ≥39. 45# steel impact toughness value αkv (J / cm2): ≥49 (5), hardness: unheated, ≤229HB; annealed steel, ≤197HB. 09CUPCRNI-B steel properties, 45# steel chemical composition % (Carbon: 0.42 to 0.50, Silicon: ≤0.40, Manganese: 0.50 to 0.80, Sulfur: ≤0.045, Phosphorus: ≤0.045, Chromium: ≤0.40, Nickel: ≤0.40, Molybdenum: ≤0.10).
