12Cr1MoV high pressure boiler tube was developed from the original 12xm steel (0.5% Cr-Mo-V) to 12x1m (1% Cr-Mo-V) steel by increasing the Cr content. The chemical composition of 12Cr1MoV Alloy Seamless Steel Tube is simple, the total alloy content is less than 2%, and it has excellent process and physical properties. At present, it has been listed in the seamless steel pipe standard for high pressure boiler in China (GB5310-2008). Similar steel grades widely used abroad include ASTM a405 p24 (1% CrMoV, USA), bs3604 (0,5% CrMoV, l% CrMoV, UK), din13crmov42, 10crmosiv7 (Germany), etc.
At present, 12Cr1MoV Seamless Steel Pipe is widely used in Superheater, header and main steam conduit of high pressure, ultra-high pressure and subcritical power station boilers at home and abroad. This steel has become one of the main materials of power plant and boiler in China's power industry.
At present, 12Cr1MoV Seamless Steel Tube is mainly used in the following aspects:
(1)Mainly used for superheater pipe, air pipe, main steam pipe, reheater pipe and other parts of boiler equipment, especially in high-pressure and ultra-high-pressure boiler, 12Cr1MoVG low alloy heat-resistant steel is widely used.
(2)Mainly used for the main shaft,] impeller, rotor, fastener (bolt and nut), cylinder, nozzle chamber, lubricating valve, diaphragm and some blade materials of steam turbine.
(3)Mainly used to reduce the working temperature of rotor and blade in hot gas engine to about 550 ℃, so as to expand the application of low alloy heat-resistant steel in gas engine.
(4)Can be used to manufacture gas turbine rotor, impeller, fastener and other parts with working temperature below 570 ℃.
(5)Mainly used for manufacturing furnace pipe, heat exchanger and other heating surface pipes in chemical and petroleum equipment.
