Q370q steel is a kind of bridge steel plate. It is delivered in hot rolled, normalized condition.There are three quality levels Q370qC, Q370qD, and Q370qE. Bridge steel Q370qC, Q370qD, EN10025-4 S275M S275ML mateiral and Q370qE steel plates have different impact temperatures: C represents 0℃, D represents -20 ℃, and E represents -40℃. Q370qC-Z25 steel plate can be hot-rolled and normalized heat-treated. When mechanical properties are required, large thickness must be normalized. The thickness of Q370q steel plate we supply is above 8mm.
On Jan. 31, 2019, BBN steel held the annual meeting with all employees, family members, and friends. It is a moment of joyand it is a moment to summarize the past and look forward.Looking back on 2018, BBN steel exported EN10025-4 S275M S275ML mateiral more than 2 million tons of steel materials to all parts of the world and made outstanding contributions to infrastructure construction at home and abroad. In 2019, BBN steel will make persistent efforts and forge ahead.
Medium and heavy plate is widely used in construction engineering, machinery manufacturing, container manufacturing, shipbuilding, bridge construction and other fields. The surface quality of medium and heavy plate mainly refers to its surface smoothness, surface defects, etc., which is one of the main quality indexes of medium and heavy plate. The surface quality of EN10025-4 S275M S275ML mateiral, medium and heavy plate not only affects the appearance of the products, but also reduces the corrosion resistance, wear resistance, fatigue limit and other properties of the steel plate.
Welded pipe, also known as welded steel pipe, refers to the steel pipe made of steel plate or strip steel after crimping and forming, with a fixed length of 6 meters. The production process of welded steel pipe is simple, the production efficiency is high, the varieties and specifications are diversified, and the equipment investment is less, but the general strength is lower than that of seamless steel pipe. EN10025-4 S275M S275ML mateiral, Welded pipes have many uses and are almost ubiquitous in our lives. However, when choosing welded pipes, we must pay attention to performance and material characteristics.
