The five treatment of the stainless steel elbow is as follows:
1, the stainless steel elbow softened and slowly extinguished: the function of this operation is to effectively decompose the carbide, to reduce its hardness, but can enhance the processing function, so that more fertile iron elements can be obtained.
2, routine treatment: the purpose is to improve the product quality of the wave iron structure casting in order to get a more balanced distribution of products.
3, quenching Transformation: this step can use elbow hardness, in other words, to further enhance the wear-resisting strength, and increase the wear resistance from inside to outside.
4. Transformation of surface hardened layer: as the name suggests, the surface hardening will be enhanced.
5. Let the stainless steel elbow be hardened and transformed to maximize the strength of the surface, but it will not change the shape of the periphery due to ductility.
