Stainless steel elbow polishing method

As a high-strength metal, stainless steel is generally difficult to polish. In the process of producing stainless steel elbow, how to polish it? Let’s take a look together.

1.Chemical polishing: Chemical polishing uses chemical substances to polish stainless steel. When polishing, it is necessary to put the stainless steel elbow into the solvent of chemical substances, and then use chemical solvent to corrode the surface of stainless steel to achieve the polishing effect. Chemical polishing is a relatively simple polishing method. with the roughness generally controlled at 10 mm.

2.Mechanical polishing: Mechanical polishing includes rough polishing and fine polishing. Mechanical polishing usually uses polishing equipment with a speed of 200-300 rpm to Polish Stainless steel. During rough polishing, chromium oxide or alumina solution is sprayed to ensure wetting of stainless steel during polishing. Fine polishing is finer than rough polishing.
