There are many production and processing processes for stainless steel coil. In this process, if there is a problem in all the processes, it will be very harmful for its characteristics. Therefore, people should pay more attention to the production and processing at that time.
Annealing temperature. Whether the annealing temperature can exceed the required temperature is very important for the production and processing of stainless steel coil. Its heat treatment is generally solid solution heat treatment, in other words, people often say that "quenching" without tube temperature is insufficient, most of them will not succeed.
Its production and processing are generally all using pure hydrogen as quenching atmosphere, and usually about 99.99%. If a part of the atmosphere is rare gas, its purity can be lower.
The other is that the wall is closed. The bright annealing furnace should be closed. It must be insulated from external gases.
This is all stainless steel coil in production and processing at that time, people should pay attention to some aspects, otherwise for the quality of goods is very harmful. 文章来源：/
