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 P355GH plate, API2WGr60 pipeline steel plate in China, our company supply API2WGr60 steel plate, API2WGr60 steel stock and API2WGr60 steel pipe with favourable price.

In recent years, in line with the development trend of iron and p355gh plate steel industry at home and abroad, we have accelerated the transformation of development mode, promoted structural adjustment, and formed a rich product series of medium and thick plates, hot rolled steel coils, profiles, steel pipes, etc., which p355gh plate are widely used in automobiles, long-span bridges, railways, machinery, ocean and so on fields. Meanwhile, we also provide deep processing for the steel materials.

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 p355gh plate are higher than that of annealed p355gh plate, but the elimination of internal stress is not as good as annealing. The normalizing operation of p355gh plate is simple, the cost is low, the productivity is high, and it is widely used in actual production.

EN10025-6 S460QL structural steel plates are European standard low alloy high strength steel materials. p355gh plate, S460QL steel plates are mainly used for building and engineering structures, such as plant structure, body steel frame components of bulldozers, loaders etc. all kinds of construction machinery, bridges, ships and so on.
