Use of T12 alloy seamless steel tube 219 x 12

 The cold rolled (dialing) seamless steel tubes are divided into ordinary steel tubes, low medium pressure boiler tubes, high pressure boiler tubes, alloy steel tubes, stainless steel composite pipes, oil cracking pipes and other steel pipes, including thin carbon thin steel tubes, alloy thin walled steel tubes, stainless steel tubes and special-shaped steel tubes. The outer diameter of hot-rolled seamless pipe is generally larger than 32mm wall thickness 2.5-75mm the cold-rolled seamless steel pipe diameter can reach 6mm wall thickness to 0. The outer diameter of 25mm thin wall tube can be less than 0 of the thickness of 5mm wall. The precision of 25mm cold rolling is higher than that of hot rolling. 12Cr1MoVG alloy seamless steel pipe T12 alloy seamless steel pipe 219 x 12 use 20Mn2A circular chain hot rolled wire rod widely used in mine, crane and ship chain and so on, with good strength, toughness and wear resistance
