6mm thick S690QL chemical composition

The pickling coil is the coil after the process of removing iron oxide from the steel surface. Pickling coil is widely used in automobile industry, such as automobile chassis system, including girder, auxiliary beam, wheel, etc.. S690QL chemical composition, Pickling coil is also used in machinery industry such as textile machinery, mining machinery, windmill, etc.. Besides, Pickling coil has application in light industrial household such as the shell of the compressor, bracket, water heater tank and other chemical oil barrels.

The wear-resistant plate S690QL chemical composition shows good wear resistance: the chemical composition of the alloy layer contains 4-5% carbon and 25-30% chromium. The volume fraction of Cr7C3 carbide in the metallographic structure is more than 50%, the macro hardness is HRC56-62, and the hardness of chromium carbide is HV1400-1800. Because of the vertical distribution of carbides in the wear direction, the wear resistance of the cast alloy with the same composition and S690QL chemical composition hardness is more than twice as that of the cast alloy with the same composition and hardness. Compared with several typical materials, the wear resistance is as follows: (1) compared with low carbon steel; 20-25:1 (2) with as cast high chromium cast iron; 1.5-2.5:1.

BBN Group's first blast furnace blast dehumidification system: The project started construction on May 2 and began trial operation on August 28. All data are balanced and stable, blast furnace output indicators have improved significantly, and the daily dehydration capacity of the two blast furnaces is as high as 124 tons, with a daily increase of about 200 tons S690QL chemical composition, and the blast furnace is running smoothly.

The company adheres to the business philosophy of "good quality, customer first, honesty and trustworthiness", and strives to provide customers with high-quality S690QL chemical composition products and excellent services. Our company's products S690QL chemical composition are widely used in petroleum, chemical, power station, boiler and other industries, mainly used in reactors, heat exchangers, separators, spherical tanks, oil and gas tanks, liquefied gas tanks, nuclear energy reactor pressure shells and other equipment.

The after-sale service of iron and steel products includes after-sale tracking service, technical guidance, transfer of relevant bills, handling of objections and many other contents. The handling of quality objections accounts for a large proportion. When dealing with these problems, we should distinguish the responsibilities, and compensate or return the inconvenience or loss caused to users due to steel.
