Propelling heat expansion of seamless steel pipes by local induction heating is an effective method for producing large-diameter thin-walled seamless pipes. […]

The factors that affect the intergranular corrosion resistance of TP321 stainless steel seamless steel pipe are analyzed, and the reasons that may lead to the reduction of corrosion resistance are studied from the aspects of chemical composition , metallo […]

By dealing with thermal simulative tester GLEEBLE3500 ，TP321 austenitic stainless steel has been conducted isothermal and constant strain compression test and effect of deformation degree and extrusion temperature on actual grain size have been analyzed […]

The s235jr seamless pipe is mainly made of Q235 . This material is generally used to make auto parts and mechanical parts. It has good corrosion resistance and mechanical properties, and has a long service life. The s235jr seamless pipe refers to the stee […]

Although the Q460D steel is widely used for plat e-making， it's very difficult to make the seamless tube with this type of steel. Nevertheless， a hi-strength and hi-toughness large-sized heavy-wall structure-purposed seamless tube in Q460D steel is succe […]
