ASTM A270 TP304 austenitic stainless steel seamless food grade pipe for food industry
ASTM A270 TP304 austenitic stainless steel seamless food grade pipe for food industry
ASTM A270 TP304 seamless food-grade pipe is austenitic stainless steel designed specifically for the dairy and food industries, characterized by a special surface treatment, high cleanability, and corrosion resistance. It conforms to the ASTM A270 standard, which specifies mechanical properties such as tensile strength and elongation, ensuring the pipe can withstand the stresses of service. "TP304" refers to Type 304 stainless steel alloy, a low-carbon chromium-nickel alloy with excellent formability, weldability, and oxidation resistance.
What is TP304 pipe?
A312 TP304 pipe is typically formed from round billets using push-pull technology. It is more corrosion-resistant than standard 304 stainless steel pipe. Our 304 stainless steel seamless pipe has a low carbon content, giving it excellent weldability and formability.
