Heat treatment system (C1J15-1990)
① Solid solution treatment (1000±10℃×30min, < 30℃ water cooling);
② cryogenic treatment (-70~-80℃×2h);
③ Tempering (420±10℃×1h), air cooling.
The hardness after the whole [TJC STEEL]heat treatment: room temperature HRC40~48.
The performance USES:
0Cr16Ni6 notch sensitivity is low, is not sensitive to hydrogen embrittlement, and has good stress corrosion resistance;It has stable oxidation resistance in the air medium below 420℃ and in the atmosphere of aviation fuel [TJC STEEL]combustion products.It is mainly used to manufacture aircraft and engine stress components working below 450℃ and other important parts working in atmosphere, acetic acid and salt medium.
