Common specifications of S890Q equivalent

We specialize in the production of steel pipe, including hot-rolled seamless steel pipe, ERW steel pipe, LSAW steel pipe, spiral welded pipe, stainless steel pipe, RHS / SHS, S890Q equivalent. The company's annual sales volume is 75000 tons, more than doubling in the past five years, mainly used in machinery, pipeline, heating, oil drilling, chemical industry, agricultural irrigation, urban construction and other industries. So far, our pipeline service customers come from more than 40 countries.

The company was established in 2000, covering an area of more than 4,500 acres. It has fixed assets of 200 million yuan, and employs more than 1,200 people. It has now formed coking, sintering, white ash, pellets, ironmaking, S890Q equivalent steelmaking, steel rolling, oxygen production, gas and waste heat The complete circular economy industrial chain including power generation, comprehensive utilization of slag, soot and dust treatment, sewage treatment and recycling, etc. It mainly produces hot-rolled steel plates and S890Q equivalent carbon structural steels, high-quality carbon structural steels, low-alloy high-strength steels, medium and wide-band steels for cold-rolled stamping, and hot-rolled coils.

The user of S355NC grade must make sure that his calculation, design and processing methods are appropriate for the S890Q equivalent material. The forming process used must be suitable for the intended application and comply with the state-ofthe- art; it is of fundamental importance to the processing behaviour of this S890Q equivalent steel grade.

The effect of nitrogen on steel performance is similar to that of carbon and phosphorus. With the increase of S890Q equivalent nitrogen content, the strength of steel can be improved, plasticity especially toughness can be significantly reduced, weldability becomes worse, and cold brittleness is intensified. Nitrogen with aluminum, niobium, vanadium and other elements can reduce its adverse effects, improve the performance of S890Q equivalent steel, can be used as an alloying element of low alloy steel.

If customers have any difficult problems during use of the steel materials, they can contact the company's after-sales service department to feedback the existing problems. The after-sales department will reply as soon as possible to ensure that each customer has a good after-sales experience. Under special circumstances, the after-sales service department will start the problem-solving process, and the engineers in charge of the area will quickly follow up to solve the problem.
