09CuPCrNi-B chemical composition dimensional tolerance

Grade S355J2 is an unalloyed welded structural steel with guaranteed impact work at a temperature of -20ºС. It is used in industrial and civil engineering, as well as in the construction of oil and gas platforms, other offshore structures, power transmission towers and other metal structures. Steel S355J2 is actively used to manufacture elements of heavy ground and underground equipment (bulldozers, excavators and dump trucks), railway wagons and agricultural machinery.

40Cr steel belongs to alloy structural steel. 09CUPCRNI-B chemical composition, 40Cr steel has good comprehensive properties, low temperature impact toughness and low notch sensitivity after quenching and tempering on the basis of high-quality carbon structural steel No. 40. 40Cr steel mechanical properties: tensile strength: ≥ 980mpa, yield strength: ≥ 785MPa, elongation after fracture: ≥ 9%, elongation after fracture: ≥ 45%, impact absorption energy: ≥ 47J. 40Cr steel chemical composition: C: 0.37-0.44, Si: 0.17-0.37, Mn: 0.50-0.80, Cr: 0.80-1.10.

As the thickness and hardness of 09CUPCRNI-B chemical composition increase, the tendency to crack at the cutting edge increases. In order to prevent the 09CUPCRNI-B chemical composition from cutting cracks, preheating should be carried out before 09CUPCRNI-B chemical composition cutting. Special attention should be paid to preheating to make the entire 09CUPCRNI-B chemical composition interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole 09CUPCRNI-B chemical composition cannot be preheated, the partial preheating method can be used instead.

We have a professional production team and high-quality production equipment, and we also have a great 09CUPCRNI-B chemical composition advantage in price, with its own factory, large-scale production to reduce the price. Strictly control each production line to ensure the 09CUPCRNI-B chemical composition production of high-quality steel plates, steel pipes and other products that meet customer requirements.

Our company will accept the product quality objection registration record, pass it to the 09CUPCRNI-B chemical composition production unit and relevant departments, and timely coordinate the supervision of product 09CUPCRNI-B chemical composition quality objection. Our company coordinates the relevant department personnel to the customer unit to carry on the investigation, the processing.
