The main technical requirements to tell reliable material S690QL1 supplier

ASTM A217 stainless steel castings in the product form of valves, flanges, fittings and other pressure-containing parts. ASTM A217/A217M covers one grade of martensitic stainless steel and nine grades of ferritic alloy steel which are primarily utilized in high-temperature and corrosive service. It includes C-Mo alloy steel: Grade WC1; Cr-Mo alloy steel: Grade WC4, WC5, material S690QL1, Grade WC6, WC9, WC11, C5, C12; Cr-Mo-V alloy steel: Grade C12A; and Chromium Steel: Grade CA15.

The company produces seamless steel pipes such as GB, ASTM, etc. all year round, including low and medium pressure boiler steel pipes, high pressure boiler steel pipes, material S690QL1 seamless steel pipes for ships and petroleum cracking material S690QL1 steel pipes, Seamless steel pipe, oil sleeve steel pipe, pipeline steel pipe, hollow sucker rod, common fluid steel pipe, structural pipe, kauden steel pipe, seawater corrosion-resistant titanium pipe and imported alloy steel pipe are used for high-pressure fertilizer equipment. The products are widely used in petroleum, chemical, electric, boiler, ship, machinery and other industries, and have been sold all over the country. Many material S690QL1 products have been exported to the Middle East, India, Southeast Asia and Europe and America.

The purpose of material S690QL1 quenching is to transform the supercooled austenite into martensite or bainite to obtain a martensite or bainite structure, and then cooperate with tempering at different temperatures to greatly improve the strength, hardness, performance, fatigue strength, toughness, and wear resistance etc. of material S690QL1. So as to meet the different use requirements of various mechanical parts and tools. Quenching can also help to get the ferromagnetic, corrosion resistance and other special physical and chemical properties of certain special steels.

The alloying principle of low alloy high strength steel is mainly to improve the strength of steel by solid volume strengthening, fine grain strengthening and precipitation strengthening produced by alloy elements. At the same time, the effect of reducing the ductile brittle transition temperature of steel by fine grain strengthening is used to counteract the adverse effect of carbon nitride precipitation strengthening on the rise of ductile brittle transition temperature of steel, so that the material S690QL1, low alloy high strength steel can obtain high strength while maintaining good low temperature performance.
