S355J2W low alloy material spec

The company specializes in the research and development, production and sales of S355J2W low alloy seamless pipes, longitudinally welded pipes, large-diameter welded pipes, API 5L welded pipes, spiral welded pipes, and large-diameter thick-walled straight seam steel pipes. The company has S355J2W low alloy five production lines in three major production workshops: large-diameter longitudinally welded pipe production workshop,S355J2W low alloy rolled steel pipe production workshop, and thermally expanded steel pipe production workshop, with an annual production capacity of more than 100,000 tons.

15crmo alloy pipe is a kind of seamless steel pipe, and its performance is much higher than ordinary seamless steel pipe. Because this kind of steel pipe contains more Cr, its high temperature resistance and corrosion resistance are not comparable to other seamless steel pipes, so alloy pipes are widely used in petroleum, chemical, electric power, boiler and other industries.

S355J2W low alloy, Alloy plate is a steel plate with multiple uses because it has the following characteristics. First, better abrasion resistance. Alloy plate is more wear-resistant than ordinary steel plate. It does not scratch or wear, and has applications such as floor steel plate laying, steel plate wall and so on. Second, the alloy plate has higher strength. Third, the alloy plate is more resistant to high and low temperatures. Fourth, the alloy plate has outstanding corrosion resistance. As the steel laid on the ground, it must have good corrosion resistance. Because it will suffer from wind and rain for a long time, it must be very resistant, otherwise it will be damaged once it is corroded.

The basic principle of S355J2W low alloy, heat treatment of steel: put the metal workpiece in a certain medium and heat it to a suitable temperature, keep it in this temperature for a certain time, and then cool it at different speeds. Objective: to obtain the desired structure and properties by means of heating, heat preservation and cooling, so as to make the metal workpiece have the required mechanical, physical and chemical properties.

S355J2W low alloy, HP265 steel with the thickness range is 1.2-12mm. HP265 steel’s mechanical properties is include the yield strength more than 265MPa, tensile strength is 410-520MPa. The chemical composition of HP265 steel is C element content is 0.18, the Si element content is 0.10, the Mn element content is 0.80, the P element content is 0.025% max, the S element content is 0.015% max.

The company has sufficient stocks and complete specifications. The common carbon steel plates, marine plates, S355J2W low alloy and storage tank steel plates sold are all produced by large state-owned steel companies such as Shougang, Hegang, Taiyuan Iron and Steel, with quality assurance and worry-free after-sales. The company develops and grows under the concept of seeking innovation in stability and advancing with the times for development. After a short period of development, it has begun to take shape.
