Welcome to BBN High Strength Steels Factory
The strength indexes of S690QL material hardness pipeline steel mainly include tensile strength and yield strength. At the same time, the yield strength ratio (yield strength to tensile strength ratio) of pipeline steel is also required, which is generally in the range of 0.85-0.93. Pipeline steel shall have enough high impact toughness (crack initiation and crack arrest toughness). For the base metal, when the toughness of the S690QL material hardness material meets the requirements of crack arrest, its toughness generally can also meet the requirements of crack prevention.
BEBON has been engaged in the piping industry as a professional manufacturer and supplier of steel plates, ship plates, corten steel, pressure vessels, S690QL material hardness steel pipelines, seamless pipe and ERW pipes since the inception. We provide integrated solutions to whole-package procurement covering miscellaneous ferrous and non-ferrous piping components. The products are widely used in oil & gas project, subsea or offshore platform piping, S690QL material hardness chemical & pharmaceutical pipeline, power plant, sewage treatment, water supply piping, heat exchange application.
Superior process production line advantage sdf: The company has focused on weathering steel S690QL material hardness, pressure vessel plate, oil tank plate, pipeline steel plates, and steel welded structures for many years, and has a strong factory scale; one of the domestic excellent weathering steel manufacturers, serving customers all over the world; using frequency conversion and microcomputer program control, the equipment is highly automated; Improve product efficiency and improve product quality.
Alloy elements have the most significant strengthening effect on steel in quenched and tempered state. The primary purpose of adding alloying elements to steel is to improve the hardenability of steel and to ensure that martensite is easily obtained during quenching. The second is to improve the tempering stability of the steel to keep the martensite at a higher temperature, so that the carbides precipitated during the tempering of the quenched steel are finer, uniform and stable. In this way, under the same conditions, alloy steel has higher strength than carbon steel, S690QL material hardness.
There is a careful, patient, enthusiastic and thoughtful after-sales team, a professional distribution, ultra-efficient warehouse and logistics center, a marketing team with marketing expertise, an innovative technology center with strong steel technology, an experienced manufacturing center with rigorous professionalism Quality Inspection Center, an operation team with many years of administrative management experience. Such a strong combination of teams makes BEBON a steel giant in Henan Province.
