Black MS sheet 08CuPVRE steel chemistry supplier

Pipeline steel plate API 5L Gr.B, 08CuPVRE steel chemistry, X42, X46, X52, X56, X60, X65, X70, X80 is a key steel material for manufacturing straight-seam submerged arc welded pipe for high-pressure long-distance natural gas pipeline. X80 pipeline steel is currently the highest-grade pipeline steel in engineering application in the world. The our company produced X80 pipeline steel plates are successfully used in natural gas pipeline project with the largest wall thickness and diameter.

The composition characteristics of low alloy high strength steel are low carbon ≤0.20%, low alloy, and total alloying elements is less than 3%. The low carbon content is to meet the process performance requirements of 08CuPVRE steel chemistry, low alloy high strength steel for engineering structural parts such as plasticity, toughness, weldability and cold deformation; adding a small amount of alloying elements (mainly Mn) to achieve the purpose of improving mechanical properties. Mn not only has a significant strengthening effect on ferrite, it can also reduce the cold brittle temperature of steel, increase the amount of pearlite in the steel, and further improve the strength.

The user of S355NC grade must make sure that his calculation, design and processing methods are appropriate for the 08CuPVRE steel chemistry material. The forming process used must be suitable for the intended application and comply with the state-ofthe- art; it is of fundamental importance to the processing behaviour of this 08CuPVRE steel chemistry steel grade.

Before delivering our hot rolled plate product we apply various tests to check the quality of carbon steel 08CuPVRE steel chemistry plates such as- mechanical test, chemical test, hardness test, toughness test, eddy current test, impact test, micro test, flaring test, flattening test, etc. We are provided best packing for structural steel plates to avoid rust. Our after-sales service team will contact you if you have any question.
