As a leading steel supplier of raw material, BBN steel company is committed to serving the majority of manufacturing, ships building, construction, power plant, oil storage, and mining companies. With a good reputation, perfect sales network and thoughtful after-sales service, customers have spread to more than 70 parts of the world.

Boiler vessel plate: it is used to manufacture various boilers and important accessories. Because the boiler steel plate is in the medium temperature (below 350 ° C) and high pressure state, in addition to bearing high pressure, it is also subject to impact, fatigue load and water and air corrosion. EN S275ML steel. It is required to ensure a certain strength and good welding and cold bending performance. It is a special steel plate for pressure vessel, which is widely used in China.

The most remarkable characteristic of low alloy high strength steel is high strength. In hot rolling or normalizing state, the strength of low alloy high strength steel is generally 30% - 50% higher than that of corresponding carbon engineering structural steel, EN S275ML steel. Therefore, it can bear large load. Engineering structures are usually large or huge, and the weight of the component itself often becomes an important part of the load. When the strength of the structural material is improved, the self weight of the component can be significantly reduced, and its ability to bear other loads can be further improved.

The thermal conductivity of NM360 wear-resistant plates is only 1/2 of that of carbon steel, EN S275ML steel, and even in the high temperature stage of 900-1000℃, the thermal conductivity is lower than that of carbon steel at the same temperature. Therefore, the heating rate of the NM360 wear-resistant plate, especially in the low temperature stage, should be lower than that of carbon steel to avoid excessively steep internal temperature gradients and cracks.

We have replenish steel materials stocks, now there are huge stocks of S355JR, A36, EN S275ML steel A572 Gr 50, 16Mo3, A516 Gr 70, ABS grade A, AH32, AH36, EH36, SPA-H, SG295,SM700C etc steel materials. We can arrange delivery for those stock steel products within short time. Meanwhile, we also provide further processing for the EN S275ML steel steel materials, such as cutting, drilling, bending, welding, etc. Please do not hesitate to contact us if you have any steel demands.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
