Fast delivery usage of hardox 500 sheet for structural

In terms of steel for offshore platforms, steel also plays an important supporting role. Because the offshore platform is immersed in sea water for a long time, it also needs to withstand the test of various harsh sea conditions such as storms, waves, glaciers, etc. Therefore, the steel usage of HARDOX 500 sheet for offshore platforms requires not only high strength, but also good corrosion resistance, low temperature toughness and resistance, lamellar tearing performance, etc.

After 1975, our equipment includes blast furnaces, electric furnaces, vacuum refining furnaces, and electroslag furnaces. The product varieties are relatively complete. Plates, usage of HARDOX 500 sheet tubes, wires, belts, and profiles have a certain scale, including magnetic, elastic, expanded, bimetal and other precision alloy materials for national defense and electronics industries. In 1982, these plants produced 364,000 tons of usage of HARDOX 500 sheet steel and 542,000 tons of steel.

Vanadium mainly exists in the form of carbide in usage of HARDOX 500 sheet and so on steel. Its main function is to refine the structure and grain size of steel and reduce the strength and toughness of steel. When the solid solution is dissolved at high temperature, the hardenability is increased; conversely, if it is in the form of carbide, the hardenability is reduced. Vanadium increases the tempering stability of quenched steel and produces secondary hardening effect. The vanadium content in steel, except high speed tool steel, is generally less than 0.5%.

Winning the battle against pollution is a major political task. The Department of Ecology and Environment of Henan Province has issued the "Precise and Scientific Implementation Plan for Special Actions for the Prevention and Control of Air Pollution in Autumn and Winter". The "Plan" clarified the province's environmental air quality "consolidation, optimization, and improvement" governance goals, and proposed the reduction of coal combustion, industrial pollution control, diesel truck pollution control, urban and rural non-point source pollution control, and pollution weather response. The 10 key tasks have laid the foundation for the improvement of air quality during the 14th Five-Year Plan.
