What is A213 TP304?

304 seamless tube for heat-transfer service. Chemistry: 18Cr-8Ni (approx. 18–20% Cr, 8–10.5% Ni). min tensile ~515 MPa (75 ksi), min yield ~205 MPa (30 ksi) for common A312 pipe grades — confirm PO / ASME SA-312.

Typical applications

• Boiler, superheater and heat-exchanger tubes
• Food, dairy, brewery and pharmaceutical process lines
• Architectural / structural stainless piping where chloride load is moderate
• Chemical handling of mild corrosives and clean utilities

Selection guidance

Choose 304 for general corrosion resistance and formability. Prefer 304L for heavy welded sections; 304H when elevated-temperature carbon is required; move to 316/316L for chloride / marine exposure. Confirm OD × average/min wall, length and U-bend needs on the enquiry.

Frequently asked questions — ASTM A213 TP304 Seamless Tube

What is ASTM A213 TP304?

A213 covers seamless ferritic and austenitic alloy steel boiler, superheater and heat-exchanger tubes. TP304 is the 304 austenitic grade (UNS S30400).

A213 vs A269?

A213 is the boiler/HX tube specification with tighter heat-transfer product rules. A269 is general-service stainless tube.

A213 vs A312?

A312 is pipe; A213 is tube for heat-transfer duty. Do not interchange names on the PO.

Typical uses?

Food, dairy, brewery and pharmaceutical process lines; Architectural / structural stainless piping where chloride load is moderate; Chemical handling of mild corrosives and clean utilities
