Price list of 1.8988 EN 10025-6 high strength steel material steel

The sulfur element (S element) comes from the ore and fuel coke of steelmaking. It is a harmful element in 1.8988 EN 10025-6 high strength steel etc. steel. Sulfur exists in steel in the form of iron sulfide (FeS). FeS and Fe form a low melting point (985℃) compound. The hot working temperature of steel is generally above 1150 - 1200℃, so when the steel is hot working, the premature melting of FeS compound causes the workpiece to crack, which is called "hot brittleness". It reduces ductility and toughness of steel and causes cracks during forging and rolling. Sulfur is also detrimental to welding performance and reduces corrosion resistance.

Q550D Application: This steel is mainly used in steam turbines for main steam pipes with steam parameters up to 540℃, turning guide vane ring, steam turbine baffle, baffle outer ring, and various superheater tubes, ducts and pipes with tube wall temperature ≤570℃ The corresponding forgings.

In mid-October, news from Shanxi called for the elimination of more than 20 million tons of coke oven capacity below 4.3 meters before the end of the year. By the end of October, 12.3 million tons of production capacity had been eliminated, and in November, 10.52 million tons were expected to be eliminated. In the later period, localities will successively announce plans for reducing production capacity during the heating season this year, involving 29.73 million tons of coking capacity.
