Whether 05CuPCrNi weather resistant steel plate need preheating

The company covers an area of 15,000 square meters and the plant construction area is 10,000 square meters. We have introduced more than 50 sets of advanced 05CuPCrNi weather resistant steel plate production equipment, auxiliary equipment and testing equipment at home and abroad, more than 260 employees, more than 20 middle and senior management staff, more than 10 professional and technical personnel, annual production capacity of 100,000 tons. Main products: flat steel, 05CuPCrNi weather resistant steel plate steel pipe, steel plate, section steel, steel structure processing parts, etc. We also accept incoming materials and annealing processing.

S355J0 steel is a low alloy structural steel. We can supply S355J0 structural steel plates up to 400mm, with a minimum yield strength 355MPa when plate thickness less than 16mm, min. yield strength 345MPa when plate thickness range 16mm to 40mm. Without any special rolling or heat treatment for S355J0 steel plate and sheet, 05CuPCrNi weather resistant steel plate, the abbreviated designation of this delivery condition shall be AR (As rolled).

The Performance requirements of low alloy structural steel, 05CuPCrNi weather resistant steel plate:(1) High strength: generally, the yield strength is above 300Mpa.(2) High toughness: the elongation is required to be 15% - 20%, and the room temperature impact toughness is greater than 600kJ/m ~ 800kJ/m. For large welded components, higher fracture toughness is required.(3) Good weldability and cold forming property.(4) Low cold brittle transition temperature. (5) Good corrosion resistance.

The thermal conductivity of NM360 wear-resistant plates is only 1/2 of that of carbon steel, 05CuPCrNi weather resistant steel plate, and even in the high temperature stage of 900-1000℃, the thermal conductivity is lower than that of carbon steel at the same temperature. Therefore, the heating rate of the NM360 wear-resistant plate, especially in the low temperature stage, should be lower than that of carbon steel to avoid excessively steep internal temperature gradients and cracks.

Delivery status: 16MnDR steel plate is normalized or normalized and tempered. 6-60mm16MnDR-40℃ impact, 60-120mm16MnDR-30℃ impact.
Ultrasonic testing of 16MnDR steel plates: The 05CuPCrNi weather resistant steel plate plates delivered in the normalized or normalized and tempered state with thickness greater than 20mm and the steel plates delivered in the quenched and tempered state with thickness greater than 16mm shall be ultrasonically tested one by one.
