P355NL1 steel tensile strength Rm:630-450MPa.If high demands are made on notch impact strength and aging resistance. It is mainly used in steam boiler and pressure vessel construction. S355J0WP MTC plate, P355NL1 plates can be processed with all known welding methods. Welding is possible both with the machine and by hand. Preheating is usually not necessary unless the outside temperature is below 5°C. Then preheating to about 150°C is recommended.

The mechanical properties of 30CrMo steel are as follows: tensile strength 930 MPa, yield strength 785 MPa, elongation after fracture 12%, impact absorption energy 63 J. S355J0WP MTC plate, 30CrMo steel has high strength and toughness. When the temperature is lower than 500℃, 30CrMo steel has good high-temperature strength, good machinability, medium cold bending plasticity, high hardenability and good welding performance. 30CrMo steel is generally used in quenched and tempered condition.

"Our mill has three production lines:1).2500mm production line (Width: 1600-2300mm, S355J0WP MTC plate Thickness: 6-30mm, Annual capacity: 1,600,000 Tons; 2).3500mm production line (Width: 2000-3050mm, Thickness: 10-80mm, Annual capacity: 2,000,000 Tons; 3).4300mm production line (Width: 1500-4100mm, Thickness: 6-300mm, Annual capacity: 1,800,000 Tons; The weight of each ingot can reach S355J0WP MTC plate 44 tons, which is at the leading level in China. In addition, we have a 1700mm hot-rolled coil production line (width range: 900-1550mm, thickness range: 1.2-25.4mm, annual S355J0WP MTC plate production capacity: 3.5 million tons."
