Welcome to BBN High Strength Steels Factory
Low-alloy high-strength steel grades are designed to have quite good notch toughness for their intended structural use. The applicability of the notch toughness of specific grades of low-alloy high-strength steel is either based on existing use experience or combined with the results of the impact test of notched specimens. In order to meet the very strict requirements of certain applications, some S690QL equivalent material, low-alloy high-strength steels produced have excellent notch toughness. For example, controlled hot rolling technology is usually used to produce low-alloy high-strength steel plates for the manufacture of welded line pipes. Such steel pipes need to meet the requirements of relevant standards for notch toughness.
From the name, we can clearly know that seamless pipe is seamless steel pipe, which is different from welded pipe. Seamless pipe is actually a kind of steel with hollow section. S690QL equivalent material, Seamless pipe has many advantages, such as: 1, the compressive capacity of seamless pipe is very good, the place with high bearing strength will not crack, and its bearing capacity is very good. 2. Seamless pipe has no welding point, so it is more corrosion-resistant and can bear larger pressure.
The company's main business: ship plate, S690QL equivalent material low alloy plate, automobile steel, high-strength plate, pipeline steel, boiler steel plate, weathering plate, wear-resistant plate, bridge plate, pressure vessel plate, steel plate, steel processing, etc. The company takes the implementation of high-end, S690QL equivalent material high-quality, deep processing, strengthening the main business, diversified operation, group operation, enterprise transformation and upgrading as its development strategy, and makes all efforts to be your professional S690QL equivalent material steel supplier and partner.
The global share of my country's steel production has increased substantially. In the first nine months of 2020, my country's crude steel output accounted for 58% of the world's total, pig iron accounted for 69%, and imported iron ore accounted for 71% of global iron ore exports. "Such a high proportion is a manifestation of the effective control of the epidemic situation in our country and the strong demand. As the situation of epidemic prevention and control in various countries gradually improves, the proportion of my country's output will gradually decline." Luo Tiejun said.
