API2WGr60 material is a special material for pipeline steel. It is mainly used to transport large-diameter welded steel pipes such as oil and natural gas for hot-rolled coils or thick and wide plates. In addition to high compressive strength, it also requires high low temperature toughness and excellent welding performance. As a leading supplier of A572 grade 42 high strength steel, API2WGr60 pipeline steel plate in China, our company supply API2WGr60 steel plate, API2WGr60 steel stock and API2WGr60 steel pipe with favourable price.
The company now has A572 grade 42 high strength steel oversea market department, sales and supply department, finance department, logistics department, technical equipment department, quality management department, production department and other departments. The staff with college degree or above accounted for more than 80%, and there were more than A572 grade 42 high strength steel 30 professional and technical personnel. The LSAW pipe production line can produce welded pipes with Φ350-1800mm, wall thickness 6-80mm, and length 2-12m.
Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized A572 grade 42 high strength steel are higher than that of annealed A572 grade 42 high strength steel, but the elimination of internal stress is not as good as annealing. The normalizing operation of A572 grade 42 high strength steel is simple, the cost is low, the productivity is high, and it is widely used in actual production.
The alloying principle of low alloy high strength steel plate mainly uses solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements to improve the strength of low alloy high strength steel plate, A572 grade 42 high strength steel. At the same time, the effect of fine grain strengthening on the reduction of ductile brittle transition temperature of low alloy high strength steel platel is used to offset the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that low alloy high strength steel plate can obtain high strength while maintaining good low temperature performance.
The company has passed the ISO9001: 2008 quality system certification, strictly implemented the ISO9001 quality management system. Besides, we have continuously improved the after-sales service network to make every effort to provide more convenient, accurate and faster services for all customers. We will supervise the production, control the quality in the factory, Inspect the cargo before shipment, Issue the test report to sales department. From the steel prodcution to steel delivery, we always focus the whole process.
