12Cr1MoV alloy steel pipe 

12Cr1MoV alloy steel pipe has lasting strength value with high ductility and persistent stretching. good resistance and weldability, but before welding  it should be preheated to above 300 °C.

 

Usage:

High-pressure, subcritical power station boiler superheater header and main steam conduit widely used kinds of steel. 580 ℃ still has a high thermal strength and anti-oxidant properties, have higher durable plastic. The production process is relatively simple, and good weldability, but normalizing cooling rate sensitive. 580 ℃ long-term use will produce pearlite spheroidization.
