**0Cr15Mo Stainless Steel Plate (0Cr15Mo Steel Strip).
0Cr15Mo ferritic stainless steel, in addition to the general corrosion resistance of stainless steel, has excellent local corrosion resistance such as chloride stress corrosion, pitting corrosion resistance, crevice corrosion resistance, etc.
Ferritic stainless steel has high strength and low tendency to cold work, with a thermal conductivity of 130 150% of austenitic stainless steel and a linear expansion coefficient of only 60 70% of CR-Ni austenitic stainless steel.
Due to the low carbon content of ferrite, grains tend to grow during heating, and these stainless steels do not undergo phase changes from hot working to room temperature cooling.
Therefore, once the grain grows, its coarse grains cannot be eliminated by heat treatment, so that its room temperature performance is reduced.
Suitable smelting method (VOD+LF external refining) :* carbon and nitrogen content control and deoxidation process technology.
As well as the forging process:
The reasonable heating temperature of 0Cr15Mo stainless steel is 900 920
According to the heat treatment experiment, the annealing temperature is 800 820, and the heat preservation for 10h is suitable.
It can obtain products with a grain size of more than 4 to meet the application needs of domestic nuclear power steam turbine customers.
A large number of 0cr15mo stainless steel ingots, accept special specifications to order, can provide 0cr15mo stainless steel forged bar, 0cr15mo hot rolled stainless steel plate, 0cr15mo hot rolled stainless steel strip, 0cr15mo cold rolled stainless steel plate, 0cr15mo cold rolled stainless steel coil, 0cr15mo cold rolled stainless steel strip.
