HV300-600, 2B BA and 2Cr13 cold rolled Stainless Steel Coils for Steam Turbine Blades
2Cr13 cold rolled stainless steel strip with thickness:0.1-0.8mm width: 10-240mm HV300-600 Surface:2B BA
Description:
2Cr13 quenching state high hardness, good corrosion resistance. For steam turbine leaf blade.The 2Cr13 density 7.75g/m3, 2Cr13 quenching hardness is: Average the 2Cr13 quenching temperature in 980 ~ 1050 ℃, take the 980 ℃ heating oil quenching hardness is significantly lower than 1050 ℃ heating oil quenching, 980 ℃ oil quenching hardness of 45 to50HRC 1050 ℃ oil quenching hardness after high 2HRC. But the the 1050 ℃ quenching organization coarse grain brittleness. Recommends using 1000 ° C Hardening can get a better organization and hardness. 2cr13 stainless steel 2Cr13 martensitic stainless steel, welded to preheat. And Q235 welded austenitic stainless steel electrode without preheating, such as are A302.A307 line. Welding to control the dilution rate of the weld does not swing the welding, using a smaller current
Applications:
Steam Turbine Blades.and other kinds of blades.
