Manufacturing Process and Micro-structure Properties of Ni-Cr-Mo Corrosion-resistant Alloy Seamless Tube
摘要
Abstract
The Ni-Cr-Mo corrosion-resistant alloy round billet is manufactured by means of the processes of non-vacuum induction melting+LF refining+vacuum oxygen decarburization+electroslag-remelting+hot-forging.And then theΦ26.67 mm×2.87 mm Ni-Cr-Mo corrosion-resistant alloy seamless tube is developed with the said round billet via such operation steps as hot-extrusion,cold-rolling and solid heat treatment,etc.The said alloy seamless tube is tested and analyzed in terms of surface quality,dimensional deviation,chemical composition,mechanical property,technological property,metallographic structure and intergranular corrosion resistance and so on.The results show that the manufac-turing processes for both the round billet and the seamless tube of the Ni-Cr-Mo corrosion-resistant alloy are reliable;the finished tube possesses good inner and outer surface quality and high dimensional accuracy,homogeneous longitudinal metallographic structure,average grain size of Class 5.5,and excellent performance,having been satisfactory to rele-vant application requirements.关键词
