Carbon steel top 8 factories in China

The company adheres to the customer philosophy of "customer first, pursuit of excellence". With the service tenet of "low price, excellent quality, fast transportation and constant commitment", we are committed to providing S690QL equivalent material high quality and timely steel products and services for steel users all over the world. And created a good customer reputation. The main products of the company are section steel, steel pipe, thin plate, rolling plate, medium and thick plate, etc.

Our pipeline products adopt the national standard and the international standard API 5L, which can meet the needs of S690QL equivalent material pipelines working in different environments-on land in the open air and offshore deep water. Acid-resistant pipelines are produced for transporting highly acidic crude oil.

As a new type of coil material, compared with the traditional steel coil, S690QL equivalent material, the alloy steel coil and sheet has a great improvement in performance properties. The alloy steel coil and sheet has good thermal strength and oxidation resistance at high temperature. Moreover, the corrosion resistance of alloy steel coil and sheet is better. After long-term corrosion, the service life of traditional coil plate will decrease rapidly, but the new type coil, the alloy steel coil and sheet has strong corrosion resistance, and its service life is far longer than that of traditional coil plate.

Heat treatment process: heat treatment refers to a kind of process operation in which the metal or alloy can change the internal structure through certain heating, heat preservation and cooling methods in the solid range to obtain the required performance. S690QL equivalent material Heat treatment process refers to the ability to change the microstructure and properties of S690QL equivalent material after heat treatment, including hardenability, hardenability, temper brittleness, etc.

ASTM A285 grade A standard specification for pressure vessel plates. S690QL equivalent material, carbon steel, low- and intermediate-tensile strength. ASTM A285 grade A plates are normally supplied in the as-rolled condition. The plates may be ordered normalized or stress relieved, or both.Supplementary Technology: HIC Test I NACE MR0175 1 215 | Z25 | 235 | S57 | S57.1| S58 | S58.1 1S3 |S4 Thickness: 6MM to 300MM.Width: 1500mm to 4050mm.
