We are mainly engaged in corrosion-resistant steel materials and steel processing parts, the varieties include A588 grade C structural steel plate Q355NHB, Q345NS, 09CuPCrNi-A,coten-A/B,S355J0W, Q345qNHB. The application fields involve landscape gardening, outdoor structure, environmental protection equipment, railway carriage, bridge manufacturing and many other industries. The company currently has many steel extension processing capabilities such as laser cutting, bending, rolling, welding, pipe making, and surface treatment.
In the development process of more than 20 years, the company keeps pace with the times, keeps innovating its ideas, constantly adjusting its steel product A588 grade C structural steel plate structure, constantly strengthening its comprehensive competitiveness, constantly improving its management level, and more importantly, forming its corporate culture of elements and personality. The company always strives to build itself a comprehensive competitive steel A588 grade C structural steel plate supplier in the world.
As the thickness and hardness of A588 grade C structural steel plate increase, the tendency to crack at the cutting edge increases. In order to prevent the A588 grade C structural steel plate from cutting cracks, preheating should be carried out before A588 grade C structural steel plate cutting. Special attention should be paid to preheating to make the entire A588 grade C structural steel plate interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole A588 grade C structural steel plate cannot be preheated, the partial preheating method can be used instead.
30CrMnSiA steel delivery status: A588 grade C structural steel plate, 30CrMnSiA steel shall be delivered in the state of heat treatment (normalizing, annealing or high temperature tempering) or without heat treatment, and the delivery status shall be indicated in the contract. 30CrMnSiA steel has high strength, but it belongs to medium carbon quenched and tempered steel, with large hardenability, so its weldability is very poor. After quenching and tempering, 30CrMnSiA steel has high strength, enough toughness and good hardenability. And can be used as grinding wheel shaft, gear and sprocket.
As one of the large professional metallurgical manufacturers in China, the strength of the brand, quality assurance, professional after-sales. Every day we are making unremitting efforts to challenge higher quality A588 grade C structural steel plate products and more satisfactory services. Customer demand is our pursuit, and win customer satisfaction with quality. BBN after-sales team is responsible to solve the problem of technical support and quality, service complaints.
