ASTM A312 TP 304 Pipes

ASTM A312 TP 304 Stainless Steel Electropolished Pipes

ASTM A312 TP 304 Stainless Steel Electropolished Pipes are premium quality austenitic stainless steel pipes processed through electropolishing to achieve an ultra-smooth, bright, and contamination-free surface finish. This process enhances corrosion resistance, reduces surface roughness, and improves cleanability, making them ideal for high-purity applications.

Grade 304 stainless steel offers excellent corrosion resistance, good mechanical strength, and outstanding fabrication properties. When combined with electropolishing, these pipes provide superior hygienic performance and long-term reliability in critical environments.
