What is the material of 12Cr1MoV steel plate?

Main characteristics of 12Cr1MoV steel plate: compared with 12Cr1MoV steel, 12Cr1MoV steel plate has higher oxidation resistance and thermal strength.
The creep limit of 12Cr1MoV steel plate is close to the lasting strength and has high plasticity under the condition of lasting tensile.
The process and weldability of 12Cr1MoV steel plate is good, but it should be preheated to 300℃ before welding, and after welding, it should be treated with stress removal.

12Cr1MoV steel plate Chemical composition:
Si: 0.17 ~ 0.37
Mn: 0.40 ~ 0.70
Cr: 0.90 ~ 1.20
Mo: 0.25 ~ 0.35
V: 0.15 ~ 0.30

Mechanical properties of 12Cr1MoV steel plate:
Elongation after fracture (5/%) : ≥ 22
Reduction of area (bits / %) : ≧ 50
Shock absorption work (Aku2/J) : ≥ 71
Brinell hardness (HBS100/3000) (annealed or tempered at high temperature) : ≦179
Weight calculation formula of 12Cr1MoV steel plate: length*width*thickness*0.00785=kg/m.

12Cr1MoV steel plate is a kind of steel widely used in superheater, header and main steam pipe of high pressure, ultra-high pressure and subcritical power station boiler.
At 580℃, it still has high thermal strength and oxidation resistance, and high durable plasticity.
The production process is simple and the welding performance is good, but it is sensitive to normalizing cooling speed, and long-term use at 580℃ will produce pearlite spheroidization.
