Based on the P295GH boiler steel inventory steel trade, the company mainly deals in Baosteel products: color coating, zinc plating, fingerprint resistance, cold rolling, hot rolling, pickling, electrical steel and other products, and can order the futures of the company's products on behalf of manufacturers. It has established cooperative relations with more than 2000 foreign customers. At the same time, it also operates a variety of products of related iron and steel enterprises. Annual sales of p295gh boiler steel inventory steel 3.6 million tons, standing stock of 400000 tons, has developed more than 10000 users. The company has a first-class marketing service system, strong storage and transportation capacity and supporting supply, cutting distribution capacity, and gradually build it into an important marketing channel.

The quality of p295gh boiler steel inventory shall not only meet the requirements of the standard, but also be higher or stricter than the product characteristics specified in the standard, including chemical composition, structure, physical properties, chemical properties and other requirements of p295gh boiler steel inventory buyer, such as packaging, delivery time, etc.. On the basis of the quality of p295gh boiler steel inventory in line with the corresponding standards, some buyers will put forward specific requirements according to their own use requirements, which is called technical agreement. That is, some specific factors should be met according to the buyer's requirements. These requirements may be the control of chemical element content of p295gh boiler steel inventory and certain performance limit of p295gh boiler steel inventory, etc.

The p295gh boiler steel inventory, wear-resistant steel plate has the characteristics of high strength, impact resistance, beautiful appearance, high performance, high efficiency, and high cost performance, and has a broad application prospect. The wear-resistant steel plate adopts a combination of plate and beam as a whole to carry a fully welded structure. Since the plate used is thinner, in order not to reduce the strength of the plate and reduce the deformation, try to use spot welding to form a cavity, which is the structural feature and technical key of the wear-resistant steel .

Phosphorus is a very harmful element in p295gh boiler steel inventory steel. With the increase of phosphorus content, the strength, flexion ratio and hardness of p295gh boiler steel inventory steel increased, but the plasticity and toughness decreased significantly. In particular, the lower the temperature, the greater the impact on plasticity and toughness, increase the cold brittleness of steel.

The chemical composition of Q345D seamless steel pipe is as follows: C ≤ 0.18, Si ≤ 0.50, Mn ≤ 1.70, P ≤ 0.030, S≤ 0.025, Nb ≤ 0.07, V ≤ 0.15, Ti ≤ 0.20, Cr ≤ 0.30, Ni ≤ 0.50, Cu ≤ 0.30, N ≤ 0.012, Mo ≤ 0.10, Al ≥ 0.015. p295gh boiler steel inventory, Q345D seamless steel pipe has good comprehensive mechanical properties, low temperature impact toughness, corrosion resistance, cold stamping, machinability and weldability. Q345D seamless steel pipe is widely used in welding structures, such as bridges, vehicles, ships, pipelines, boilers, large vessels, etc..
