Prime quality S690QL heat treatment

Pakistan's iron and steel industry has suspended S690QL heat treatment production and operation since the outbreak, the dawn reported on April 8. Last month, Prime Minister Imran announced a rescue package for the steel industry. Recently, Pakistan's steel industry called for the resumption of production as soon as possible. The Secretary General of the association of large S690QL heat treatment steel producers in Pakistan said that steel is the pillar of Pakistan's construction industry, and Pakistan's economy cannot bear the consequences of the long-term closure of the steel industry. Any delay in the resumption of production will lead to the failure of the government's plan to revitalize the construction industry, which will have a negative impact on Pakistan's economy. It is hoped that the government will immediately resume S690QL heat treatment production in the steel industry, especially those that are able to provide shelter for workers.

The company has five major departments: steel plate production department (including quality inspection team), sales department, market development department, after-sales and logistics department, and finance department. The backbone of steel business from all over the country, with the chairman as the core, integrates self-confidence, independence, passion and responsibility, and strives for excellence! All people share the same belief: "Being a refined steel product line rewards customers, strengthen the steel industry, and realize the corporate dream!

The surface quality of pickling coil is very good. Compared with ordinary hot-rolled plate, S690QL heat treatment, the surface quality of hot-rolled pickling coil is improved in addition to the oxide scale on the surface, which is convenient for welding, oiling and painting. The accuracy of pickling coil specification is high. After leveling, the shape of the plate changes to a certain extent, thus reducing the deviation of unevenness, improving the surface finish and enhancing the appearance effect of pickling coil.

Facing the new situation and facing new goals, the company revolves around the sixteen-character development policy of “prioritizing production preservation, society-oriented, market operation, and brand creation and efficiency”. Layout the country in accordance with the modern logistics model, and accelerate the establishment of a modern integrated steel enterprise integrating steel storage, transportation, processing, and distribution.

With the increase of temperature, the yield limit of S690QL heat treatment will decrease monotonically, but the tensile strength of S690QL heat treatment will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of S690QL heat treatment. Near the blue brittleness temperature, the S690QL heat treatment strength increases and the plasticity decreases. The elongation and section shrinkage of S690QL heat treatment increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.
