BBN steel make efforts to reduce cost of EN 10025-6 S690QL equivalent

According to the different manufacturing processes, there are hot rolled steel pipes and cold drawn EN 10025-6 S690QL equivalent seamless steel pipes. BBN sells seamless pipes of different sizes, weights and grades. Customers can choose between black EN 10025-6 S690QL equivalent line pipes and galvanized line pipes. From 2-3/8" to 24", steel grade A, B, X42, X80.

Composition characteristics of low alloy structural steel, EN 10025-6 S690QL equivalent: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.

Since the welding process is often used in the fabrication and processing of steel structures, it is very important for low-alloy high-strength steels of such purpose to be welded using the arc welding process that is widely used in thin thickness plates and steel strips. Yes, the welding seam of the steel structure should have the required strength and toughness, so as to withstand the most unfavorable conditions for the intended use. At present, the development of EN 10025-6 S690QL equivalent, low-alloy high-strength steels is carried out simultaneously with the development of various welding processes. Most low-alloy high-strength steels can be welded well.

We should help solve the customer's problems in time, not just verbally, without solving the problems or shirking the responsibility. Improving after-sales efficiency can make customers feel respect. We should take their problems seriously and show sincerity. It can also give customers a good impression and reduce the negative impact.
