Pakistan launches first anti dumping sunset review on low carbon steel s235jr

Service marketing type depth processing, deep processing is more convenient for the user, to provide users with intermediate product marketing value, its typical service for general shear distribution or marketing type low carbon steel s235jr steel processing distribution (including general steel coil storage, scale shear, and the steel bar straightening, shearing, bending, welding, etc) and the apparatus of processing and distribution center.

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, low carbon steel s235jr. 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 adheres to green development, supported by scientific and technological innovation and technological progress, vigorously advocates the low carbon steel s235jr production and life style of saving, environmental protection, civilization and low carbon, adheres to the new industrialization road and the sustainable development road. Actively carry out international trade and maintain stable economic and trade relations with more than 80 countries and regions including the United States, Germany, France, the United Kingdom, Japan, South Korea and Australia.

The quenching of steel plate is to heat the low carbon steel s235jr steel to above the critical temperature, keep it warm for a period of time, and then quickly put it into the quenching agent, so that its temperature drops suddenly, and the speed of rapid cooling is greater than the critical cooling rate, and obtain the heat treatment method of imbalanced structure with martensite as the main body. Quenching increases the strength and hardness of steel, but reduces its plasticity. Quenching commonly used quenching agents are: water, oil, alkaline water and salt solutions.
