Normalizing is to heat the steel parts to 30~80℃above the critical temperature for a period of time. Then the parts are taken out of the furnace and cooled in air. Since the cooling rate of normalizing is faster than that of annealing, the strength and hardness of normalized RA hull construction steel are higher than that of annealed RA hull construction steel, but the elimination of internal stress is not as good as annealing. The normalizing operation of RA hull construction steel is simple, the cost is low, the productivity is high, and it is widely used in actual production.
09CuPCrNi-A weather-resistant steel plate is one of weather-resistant steel (that is, atmospheric corrosion-resistant steel), used in sulfur-containing flue gas, air preheater, economizer, boiler air preheater, to prevent the vicinity of acid dew point, etc. Commonly used is low temperature weathering steel, which has a strong ability to resist low temperature corrosion. This type of steel RA hull construction steel has a protective effect against corrosion.
SG255 gas cylinder RA hull construction steel steel is widely used in petroleum, chemical industry, power station, boiler, etc, used to make the reactor, heat exchanger, separator. The company is a professional gas cylinder steel exporter and a steel stockist in china. We keep more than 1000 tons SG255 gas cylinder steel coils in RA hull construction steel stock every month.
