Electrolytic polished tube (EP tube for short) is made of bright annealed tube (BA tube for short) as the base material, which is electrochemically polished to improve its corrosion resistance and oxidation resistance.

347 410 420 stainless steel EP tube advantages

Better corrosion resistance

Improved sanitary conditions

Eliminate work hardening characteristics

After polishing, the surface of 347 stainless steel electrolytic polished tube is smoother, which reduces the resistance of fluid flow and improves the transmission efficiency. It is suitable for applications in high temperature and corrosive environments, such as chemical industry, petrochemical industry, etc.

410 stainless steel electrolytic polished tube is martensitic stainless steel with high strength and hardness, reducing corrosion and dirt adhesion. It is suitable for occasions requiring high strength and good corrosion resistance, such as machinery manufacturing, automotive parts, etc.

420 stainless steel electrolytic polished tube is particularly suitable for occasions requiring high hardness and wear resistance, such as knives, molds, etc.
