The main steel plates for oil and gas pipelines are X42, X46, X52 (L360), X56 (L390), X60 (L420), X65 (L460), X70, X80. The specification range of steel plate used by the company for oil and gas pipelines: thickness 8mm-60mm. It can produce additional flaw detection requirements and Z15-Z35 tear resistance (thickness direction performance) steel plates EN 10025 S890Q high strength steel, and can also provide Z-direction performance steel plates according to ASTM A770 and other standards.

Cold rolled steel sheet has high strength, high hardness, high surface finish and is generally thin plate, which can be used for stamping. The production process of EN 10025 S890Q high strength steel, hot-rolled and cold-rolled steel plates is different. Hot rolled steel plate is rolled at high temperature, while cold rolled steel plate is rolled at normal temperature. Generally speaking, cold-rolled steel plate has better strength and hot-rolled steel plate has better ductility.

Composition characteristics of low alloy structural steel, EN 10025 S890Q high strength steel: (1) Low carbon: the carbon content of low alloy structural steel is less than 0.20% due to the high requirements of toughness, weldability and cold formability. (2) The alloy elements such as manganese are added. (3) The addition of Nb, Ti or V and other auxiliary elements: a small amount of Nb, Ti or V forms fine carbides or carbonitrides in the steel, which is beneficial to obtain fine ferrite grains and improve the strength and toughness of low alloy structural steel. In addition, adding a small amount of copper (≤ 0.4%) and phosphorus (about 0.1%) can improve the corrosion resistance. The addition of a small amount of rare earth elements can remove sulfur and gas, purify the steel, and improve the toughness and process performance of low alloy structural steel.
