Product Description

ASME SA213/ASTM A213 TP310S / UNS S31008 Stainless Steel Seamless Heat Exchanger Tube

ASTM A213 TP310S is the correct choice for a heat exchanger tube operating in continuous high temperatures (800°C – 1100°C) in oxidizing, carburizing, or mildly sulfidizing environments. It offers excellent oxidation resistance but limited creep strength above 900°C. Do not use it for aqueous chloride service or below 550°C if long-term embrittlement is a concern.

Choose TP310S when:

Operating temperature exceeds 850°C (1560°F) continuously.
Environment contains carbon (carburization, metal dusting risk).
Sulfur-bearing hot flue gas (sulfidation).
Polythionic acid SCC is a concern (refinery/Claus service).
High-temperature hydrogen service above 450°C.
You need oxidation resistance to 1150°C with good weldability.

Surface Finish Options

Finish	Code	Description	Best for
Pickled (AP)	AP	Acid bath removes scale; dull gray matte	General heat exchanger service
Bright annealed (BA)	BA	Annealed in controlled atmosphere (H₂); shiny, oxide-free	Clean service, food/pharma, low fouling
Polished	MP	Mechanically polished to Ra ≤ 0.4 µm	High-purity or aesthetic
As-drawn	No finish	No removal of drawing lubricant or oxide	Not recommended – requires cleaning

Recommendation for heat exchangers: Bright annealed (BA) gives the cleanest surface, best corrosion resistance, and no pickling residue.

Application

Syngas coolers in hydrogen reformers
Transfer line exchangers (TLE) in ethylene cracking
High-pressure superheaters / reheaters in HRSG
Tail gas reheaters in Claus sulfur recovery units
Gas/gas heat exchangers in nitric acid plants
Quench coolers in carbon black production
Suspension preheater ducts & heat exchangers in cement/lime kilns
Quench coolers in industrial incinerators / thermal oxidizers
Molten salt coolers in maleic anhydride reactors
High-temperature hydrogen reheaters in refineries

With our humidity and year-round high temps, corrosion resistance and heat transfer are always a concern. These tubes have been performing nicely.

We're dealing with aggressive fluids on the tube side. So far, no pitting or issues.

Tube ends were clean, dimensions accurate. Our fitters didn't complain about fit-up.
