Strip steel is mainly divided into hot-rolled ordinary strip steel, cold-rolled ordinary strip steel, hot-rolled high-quality strip steel and cold-rolled high-quality strip steel. The EN10025-4 steel S420M, hot-rolled carbon strip steel is made of ordinary carbon structural steel, and is hot-rolled into strip steel with a thickness of 1.80-6.00mm and a width of 50-1200mm. The hot-rolled carbon strip steel is mainly used for the manufacture of cold-rolled billets, cold-formed steel billets, welded steel pipe billets, bicycles, and small hardware products.
20G steel is boiler steel, which is similar to No. 20 carbon steel. The difference is that 20G steel has higher and stricter inspection standards than EN10025-4 steel S420M, No. 20 carbon steel for harmful impurities and internal defects. That is to say, 20G steel is specially produced for boiler pressure vessels. It is special purpose "No. 20 carbon steel". The use of 20G steel to make boilers is not because it is more resistant to burning than other steels such as EN10025-4 steel S420M, but because of its strength, toughness, ductility, weldability, temperature influence, fatigue fracture, price and cost, etc. 20G steel is most suitable for use in medium and low pressure boilers.
Converter steelmaking: The furnace body of the converter can be rotated, and the steel plate is used as the outer shell, and the refractory is used as the inner lining. Converter EN10025-4 steel S420M steelmaking does not require additional heating, because the molten iron is inherently high temperature, and it still continues to generate thermal oxidation reactions (from silicon, carbon and oxygen in molten iron).Because no more fuel is needed for heating, energy consumption is reduced.
