API 5L X70 - BEBON 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

API 5L X70 Pipe, API 5L X70 PSL1 / PSL2 Grade B Seamless

API X70 steel pipe is a carbon-based steel pipe which contains alloying compounds. Besides carbon, the API 5L X70 material include silicon, manganese, phosphorus, sulphur and niobium. The percentage of manganese and Silicon are higher in the alloy used to make API 5L X70 tubular pipes, API 5L X70 Seamless Pipe Suppliers. And elements like phosphorus, sulphur and niobium are found in trace Development of API X70 Grade Hot Rolled (HR) Coils for May 01, 2016 · Control of carbon ( 0.06%) and nitrogen ( 50 ppm) is must to produce defect free slabs of API X70 grade. Nb-V-Cr-Mo alloy design is more suitable to achieve requisite strength level (in 45°) and toughness properties consistently in API X70 HR coils intended for SW-pipe making.
