ASTM A312 TP 316 Stainless Steel Electropolished Pipes

ASTM A312 TP 316 Stainless Steel Electropolished Pipes

ASTM A312 TP 316 Stainless Steel Electropolished Pipes are premium austenitic stainless steel pipes enhanced with molybdenum for superior resistance to pitting, crevice corrosion, and chloride attack. The electropolishing process produces an ultra-smooth, bright, and contamination-free surface finish, significantly improving hygiene and corrosion resistance.

Grade 316 offers excellent strength and durability in aggressive chemical and marine environments. The enhanced chromium-rich passive layer formed during electropolishing ensures long-term performance in pharmaceutical, biotechnology, food processing, and high-purity fluid handling systems.
