What to pay attention to before using the nitriding furnace

1. General structural steel parts are quenched and tempered, the high temperature tempering temperature should be about 20 degrees higher than the nitriding temperature, and the holding time should not be too long

2. For workpieces with low impact toughness requirements, normalizing can be used, but the normalizing cooling rate should be fast, and normalizing should not be used for work with large cross-sectional dimensions.

2.38CrMoAl steel should be quenched and tempered, otherwise acicular nitrides will easily appear in the nitriding layer. The tool steel should be quenched and tempered before nitriding, and annealing should not be used

4. For some complex and precise parts, the stress can be relieved one or more times before nitriding and the temperature rises slowly
