@@@@S31803 duplex stainless steel dominates the seamless steel tube market and has an increasingly output, for its struc-ture both has austenite and ferrite;it has the advantages of austenite steel and ferrite steel in function. But the stricter requirement and the weakness in forming process affect its promotion. Through such key technologies in full-automatic forming as online narrow gap automatic welding, online automatic cutting and slender thin wall polishing, succeed in developing full-automatic forming equipment of S31803 duplex and high pressure resistant seamless steel tube, solve the technical bottleneck of full-automatic forming in seamless steel tube.
