Cold working
1. The work hardening rate is greater than that of austenitic stainless steel, so it is necessary to select the processing equipment. The cold-worked material should be in a solution heat-treated state, and intermediate annealing should be carried out when the amount of cold working is large.
2. If the cold working volume is greater than 10%, the workpiece needs to be treated with a second solid solution.
Thermal processing
1. The temperature range is 1200 950, and the cooling method is water quenching or rapid air cooling.
2. In order to obtain the best performance and creep resistance, solution treatment should be carried out after hot processing.
3. The material can be directly fed into the furnace that has been heated to 1200 °C, and it will be quickly released after holding for enough time, and the hot processing will be carried out within the specified temperature range. When the temperature of the material drops below the hot processing temperature, it needs to be reheated.
Stellite20 alloy is an alloy material with excellent wear resistance, and it retains excellent wear resistance even after long-term use in air. This material was first invented by the German Steiner in 1898. Originally used for bearings and gear units, and later for other parts. Stress corrosion cracking
