Effect of heat treatment process on microstructure and properties of S355J2W weathering steel plate

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 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, steel pipe, steel plate, section steel, steel structure processing parts, etc We also accept incoming materials and annealing processing,S355J2W weathering steel plate.

The company's headquarters has a well-established logistics distribution system, which can quickly transport the steel materials to the port through the contracted logistics companies. Professional contracted logistics companies can significantly reduce costs and various commodity-related expenses. Meanwhile, the flexible transfer ensures that the S355J2W weathering steel plate steel materials can be shipped immediately after passing the quality inspection.

No. 45 steel is commonly used medium carbon quenched and tempered structural steel. The cold plasticity of No. 45 steel is generally better than . Annealing and normalizing are better than quenching and tempering. No. 45 steel has higher strength and better machinability than Q345 steel. After proper heat treatment, it can obtain certain toughness, plasticity and wear resistance. No. 45 steel is suitable for hydrogen welding and argon arc welding, but not suitable for gas welding. Preheating is required before welding, and stress relief annealing shall be conducted after welding.

We exported 352 tons SA387GR12CL2 steel plates to Vietnam. The Vietnam customer needed the SA387GR12CL2 steel plates for their tank fabrication project urgently. We are world class steel materials supplier and exporter. Other than regular fresh production, we also keep huge stocks, so as to meet urgent demands of our customers. For the 352 tons SA387GR12CL2 steel S355J2W weathering steel plate plates, we collected from our warehouse and it only took us 3 days to arrange delivery. The customer was really impressed by our rapid shipping and spoke highly of our SA387GR12CL2 steel plates quality after use.
