Stainless steel (Stainless Steel) is the abbreviation of stainless and acid-resistant steel. It is called stainless steel that is resistant to weak corrosive media such as air, steam, and water, or is stainless steel; Corrosion steel is called acid-resistant steel. Due to the difference in chemical composition between the two, their corrosion resistance is different. Ordinary stainless steel is generally not resistant to chemical media corrosion, while acid-resistant steel is generally non-corrosive.

The hollow ball without opening is formed by first punching the steel plate into two hemispheres by cold extrusion, and then welding. The hollow ball with the exclusive opening is just like you said: it is made by first punching the steel plate into a cup shape at the bottom of the ball by cold extrusion-no weld. Of course, the closing method can be rolled or cold extruded with an abrasive tool-the upper abrasive tool is a concave spherical surface-more efficient and regular. First of all, the blanking should be calculated. Finally, there must be follow-up processing to meet the final requirements.
