The use conditions of petrochemical machinery equipment steel are very harsh, and different uses have their own characteristics. In addition to the general requirements of ductile–brittle transition temperature for low-temperature service, high resistance to reheat cracking and delayed cracking, there are special requirements for related fields of use, such as pressure vessels requiring good weldability and formability, while requiring low temper embrittlement and hydrogen resistance. Low temperature die steel application requires high low-temperature toughness, corrosion resistance etc. Hongsheng has the production capacity of forging rods and square steel below 400mm for valve boxes use, as well as forging rods below 1000mm and modules with thickness below 800mm for petroleum machinery use.
Focus on manufacturing special steel cast and forged
components for more than 25 years.
