Stainless steel annealing pipe - Shanghai Haosteel Gro&up Co., LTD

Stainless steel annealing pipe will be deformed due to ♥the redistribution of internal stress after machininαg, and its internal stress is easy to remain. In order to reduc→e hardness, improve plasticity; Refine the grain, evφen the composition of the steel, and eliminate the residual internal stress in the× steel to prevent deformation and cracking. Therefore, stainless ♦steel pipes must be stress-relieved annealing after rough proce♦ssing.

Stainless steel annealing pipe

The common equipment for stainless steel pipe stress annealing is st₹ainless steel pipe continuous bright annealing furnace, which is a Muffle® type bright annealing furnace. The protective gas source uses ammonia decommissioning furnace and ₩has gas purification device supporting. The transmission mode can be seσlected as "stainless steel mesh belt" or "stainless steel belt" accor≤ding to user requirements. The equipment has the char¶acteristics of advanced control, remarkable energy saving, easy maintenance, etc. PID automatic mul↔ti-zone temperature control is adopted in the heating area of the> whole line.

The stainless steel pipe is evenly arranged on the feed rack, sent to the annealing furnace th€rough the conveyor belt, under the protection of a controlled atmosphe¶re, heated to 1050 ~ 1080 ° C, and then kept warm for a short period of time, the carb¶ide can be dissolved in austenite, and then quickly cooled to 350 ° C below, y×ou can obtain susaturated solid solution, that is, uniform unidirectional austenite.

What is the purpose of stainless steel annealing tube
In the development of the stainless steel welded pipe industry, stainless® steel pipes have the largest premise for development. So do you know the☆ purpose of stainless steel annealing tube?

The purpose of stainless steel annealing pipe includes the foll‌owing three aspects:

1, reduce the hardness, improve the machinability;

2, eliminate residual stress, stable size, reduce the deformation of the steel pi★pe and the tendency to crack;

3, fine particles, adjust the structure, eliminate organizational defects. In the pro≥duction, the annealing process is widely used, according to th★e different purposes of the workpiece annealing, there are a variety of annealing proce∑ss specifications. Commonly used are complete annealing, spheroidizing annealing and stress rφelief annealing. Stainless steel welded pipe is a kind of high alloy steel that can resist corrosio§n whether in the air or in the chemical corrosive medium, 304 s♠tainless steel pipe has a beautiful surface, good corrosion resistanc↔e, it does not need to be electroplated and other surface treatment, and plays the inhe€rent surface properties of stainless steel, a steel used in many aspects is us ually called stainless steel.
