A387Gr91 plate is a chromium-molybdenum alloy steel. It has the functions of hydrogen embrittlement, hydrogen corrosion, hydrogen stripping, and sulfide corrosion in a hydrogen environment at medium temperature (350-480 ℃). It also has good low tempering brittleness. hot rolled RINA DH40 marine plate, A387Gr91 alloy steel is widely used in the manufacture of chemical fertilizers, petrochemicals, and thermal power plant equipment, such as synthetic ammonia reactors, coal gasifiers, shift furnaces, and hydrogenation reactors.
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, hot rolled RINA DH40 marine plate 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 hot rolled RINA DH40 marine plate 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.
Both steelmaking and ironmaking are carried out by oxidation-reduction reaction, but there are great differences between them in reaction objects: ironmaking is to reduce iron, while hot rolled RINA DH40 marine plate steelmaking is to remove excessive carbon and other impurities in pig iron, so there are relations and differences between them in actual operation. There are three main methods of hot rolled RINA DH40 marine plate steelmaking: converter, electric furnace and flat furnace. The converter steelmaking process is most widely used.
Boiler steel plate mainly refers to the hot-rolled medium and thick plate materials used to manufacture superheater, main steam pipe and heating surface of boiler fire chamber. The commonly used hot rolled RINA DH40 marine plate, boiler steel is low carbon killed steel smelted in open furnace or low carbon steel smelted in electric furnace, with carbon content in the range of 0.16% - 0.26%.
After-sales service is an important part of measuring a product good or not. After sales service can't be ignored. Good service can really make consumers feel relieved. We have always done a good job in after-sales service, so as to bring consumers a better reference when purchasing and a better experience during use of our steel materials. We will call back and follow up the performance of our steel products regularly.
