How will BP440 ballistic performance price go this week

Q355GNH weathering steel is a kind of atmospheric corrosion resistant steel, which has better corrosion resistance than BP440 ballistic performance, ordinary carbon steel by adding less alloy elements. Q355GNH weathering steel has been widely used in container, railway vehicle, bridge, building and air preheater which need to be resistant to atmospheric corrosion. Q355GNH weathering steel is characterized by the addition of less Cu, P, Cr, Ni and other alloy elements in the steel, so that a dense amorphous spinel type oxide layer with a thickness of about 50-100μm is formed between the rust layer and the base metal, which can prevent oxygen and water from penetrating into the steel matrix, slow down the development of corrosion to steel materials, and improve the atmospheric corrosion resistance.

BEBON Iron & Steel has fully passed the ISO9001 quality system certification, marine steel has passed 9 countries' classification societies, and construction steel has obtained the CE Lloyd's CE Mark certification. The main body of BP440 ballistic performance steel passed ISO14001 environmental management system certification and OHSAS18001 occupational health and safety management system certification. The main BP440 ballistic performance production processes and technical equipment of the enterprise have reached the international advanced level, the comprehensive competitiveness has entered the international advanced ranks, and the international influence has been significantly enhanced.

As the thickness and hardness of BP440 ballistic performance increase, the tendency to crack at the cutting edge increases. In order to prevent the BP440 ballistic performance from cutting cracks, preheating should be carried out before BP440 ballistic performance cutting. Special attention should be paid to preheating to make the entire BP440 ballistic performance interface evenly heated to avoid local overheating in the area contacting the heat source. If the whole BP440 ballistic performance cannot be preheated, the partial preheating method can be used instead.

Water cutting machine is called water knife for short, that is, water is used as knife. High pressure water jet cutting technology can perform any curve cutting process on any material, BP440 ballistic performance included. The heat generated in the cutting process will be immediately taken away by the water jet without harm. Material, no need or easy to reprocess after cutting, safety and environmental protection, faster, faster, more efficient.

The after-sales service personnel understand the user's ideas and needs in detail, and stand on the other side's position and interests. Actively communicate with users and help them solve practical problems. This not only solves the service problem, but also improves the customer's trust in the company.
