1cr9mo1vnbn belongs to martensitic heat-resistant steel, corresponding to the new national standard 10Cr9Mo1VNb, and the national standard 10Cr9Mo1VNb is equivalent to T91 / P91. It not only has high oxidation resistance and high temperature steam corrosion resistance, but also has good impact toughness and high and stable durability. Plastic and thermal properties. When the use temperature is lower than 620 ° C, the use stress is higher than that of austenitic stainless steel.
