The Purpose of Preheating Stainless Steel Pipe

We know that in stainless steel processing, stainless steel is a material with a variety of excellent properties. Products made from it will have a good performance in use and service life. Therefore, this type of material has been welcomed in many fields. But if you want to process it into the product we need, it needs to be carefully processed in many types of crafts in the production process to achieve the goal. Let's understand the purpose of preheating stainless steel pipes.

1. The preheating treatment of stainless steel pipes is to eliminate the unevenness of the structure

The purpose of pre-heat treatment of stainless steel pipe is to eliminate the inhomogeneity of the structure caused by ingot and forging, improve the shape and distribution characteristics of carbides, and prepare the necessary original structure for the final heat treatment. In the cold roll, if the carbide particle size is too large, the shape is poor or the segregation is serious, the final heat treatment will cause uneven matrix structure and hardness, which will increase the probability of peeling of the working layer of the roll and reduce the thermal shock resistance of the cold roll. We provide an exhaustive range of superior stainless steel flats and pre-heat treatment of stainless steel pipe. 

2. The preheat treatment of stainless steel pipes is to improve the uniformity of the structure

Stainless angle bar is a long strip of steel whose sides are perpendicular to each other at an angle. There are equilateral stainless angle bar and unequal stainless angle bar. In order to further improve the uniformity of the structure, improve the morphology and distribution characteristics of carbides, and prepare the necessary original structure for the final heat treatment of the roll, a preliminary heat treatment is adopted after the forging of the billet. The process mainly adopts spheroidizing annealing and quenching and tempering processes. Through the pretreatment of stainless steel tube, the uniformity of the roll blank structure has been greatly improved.

3. Learn about the importance of stainless steel pipe preheat treatment

The stainless steel product requires pre-heat treatment during use.

so it is important to learn about the function and method of pre-heat treatment. I hope that the above content can help you have a simple understanding and acquaintance of this kind of process.
