Low alloy coils are steel coils made of steel with a low alloy content, usually less than 3.5%. Low alloy coil materials mainly include A572 Gr 50, S355JR, SS490, ST52-3, Q345B, etc.. These grades are also the most widely used and produced low-alloy high-strength steel grades in the world. The strength of low alloy coils is about 20% to 30% higher than that of ordinary carbon structural steel, EN10025-4 steel S275M. And the atmospheric corrosion resistance of low alloy coils is 20% to 38% higher than that of ordinary carbon structural steel.

API 5L X70 steel plate/pipes, API 5L X70 steel plate/pipes, under API 5L standard, we can regard X70 steel plate/pipes as large diameter pipes. X70 steel plate/pipes is one mainly of Steel for large diameter pipes,API-X70 steel with the demands in mechanical properties of the pipes followed the API specification for grade X70 (YS is 485MPa, TS is from 600-750 MPa).It is well known that a low carbon bainitic microstructure offers an excellent combination of strength and toughness.

Plasma cutting has a wide range of applications. With different working gas, it can cut various kinds of metals that are difficulty to handle by oxygen cutting. Plasma cutting is fast and efficient when cutting metal with small thickness. The EN10025-4 steel S275M cutting speed can reach more than 10m/min. Plasma cutting can get a clean, neat, non stick slag cutting surface, while the deformation and thermal effect of the incision are small, its hardness change is little, and the cutting quality is good.

our company is a professional EN10025-4 steel S275M API 5CT N80 casing pipe steel exporter and a steel Stockist in china. We keep more than 1000 tons API 5CT N80 casing pipe steel in stock every month. If you want to get the API 5CT N80 casing pipe steel price, please do not hesitate to contact us. Any need in API 5CT N80 casing pipe EN10025-4 steel S275M Chemical Composition and Mechanical Properties, please feel free to contact us by email or calling to us.

we develop very well through those years even the external environment is not conducive to the whole steel industry. With the prosperity of our group, our company always bear its staff who contributes to its growth in mind, and always on the way to improve welfare and treatment. That makes us staff and work with pleasure. On the other way, they creat a better and stronger our group. That may be one of the key factors why we develop so rapidly those years. Here we can say proudly “we are family”.

Relying on the background of high-quality steel resources and its own strong steel machining capabilities, BBN comany can not only supply various steel material products, such as steel coils, steel plates, EN10025-4 steel S275M sheet, steel pipes, and shaped steels, but also provide a variety of steel deep processing services like cutting, welding and grinding. Through continuous technological innovation and after-sales service optimization, the company has its own world on the domestic and international steel industry stage!
