The Common Heat Treatment Method and Aging Treatment of Chain

发布时间：2019/12/24 浏览次数：次

Chain commonly used heat treatment methods: annealing, normalizing, quenching, tempering, carburizing, nitriding, carbonitriding, boronizing. Aging treatment with artificial aging, natural aging treatment.

Annealing, the workpiece heated to Ac3 above 30-50 degrees, a certain time after the insulation, with the furnace slowly cooled to 500 degrees look at the space in the cooling.

Normalizing, the steel heated to Ac3 or Acm or more, after insulation removed from the furnace in the air cooling operation.

Quenching, the steel heated to Ac3 or Ac1 above, after insulation in water or oil and other coolant in the rapid cooling, has been unstable tissue.

Tempering, the quenched steel re-heated to Ac1 the following temperature, heat preservation and cooling to room temperature after the heat treatment process.

Natural aging treatment, the workpiece placed at room temperature or natural conditions for a long time storage and aging phenomenon, known as the natural aging treatment.

Artificial aging treatment, using the workpiece heated to a higher temperature, and a shorter time for aging treatment process, called artificial aging treatment.
