12Cr1MoV, alloy structural steel. Unified Digital Code: A31132. Standard: GB / T3077-1999 C: 0.08 ~ 0.15Si: 0.17 ~ 0.37 Mn: 0.40 ~ 0.70 Cr: 0.90 ~ 1.20 Mo: 0.25 ~ 0.35 V: 0.15 ~ 0.30 Key Features: This steel compared with 12CrMoV steel with more high oxidation resistance and heat resistance. Creep rupture strength limit and the value of this steel is very close, and has a high plasticity in the case of persistent tension; the process of steel with good weldability, but before welding to be preheated to 300 ℃, require post-weld stress-relief deal with. High-pressure, high pressure, sub-critical power plant boiler superheater header and main steam pipe widely used steel. 580 ℃ still has high thermal strength and oxidation resistance, a higher durable plastic. The production process is relatively simple, good weldability, but more sensitive to normalizing the cooling rate. 580 ℃ long-term use will produce pearlite ball. This steel is mainly after normalizing and tempering used for the manufacture of high voltage equipment temperature does not exceed 570 ~ 585 ℃ superheated steel pipe, conduit, coil and other corresponding forgings.
