Product Description

ASTM A268 TP430Ti / UNS S43036 / 1.4510 Stainless Steel Seamless Tube Heat Exchanger Tube

ASTM A268 TP430Ti / UNS S43036 is a titanium-stabilized ferritic stainless steel tube grade covered by ASTM A268/A268M, Standard Specification for Seamless and Welded Ferritic and Martensitic Stainless Steel Tubing for General Service. One thing need your attention -- (chemical composition) the titanium addition stabilizes carbon and nitrogen, reducing sensitization and improving resistance to intergranular corrosion after welding. Always confirm exact chemistry with the current ASTM A268/A268M edition and the mill certificate. From raw material to final inspection, our factory will strictly follow the latest version of ASTM/ASME specification and client's additional requirements if any.

Heat Treatment
TP430Ti is normally supplied in the annealed condition. Typical annealing is around:

1400–1550°F / 760–845°C, followed by air cooling or rapid cooling.

Ferritic stainless steels can suffer from:

475°C / 885°F embrittlement after long exposure around 400–550°C.
Sigma phase formation at higher temperatures in some ferritic grades.

Therefore, high-temperature service and post-weld heat treatment should be evaluated carefully.

Application
For heat exchangers specifically, it is usually selected only when the corrosion/oxidation conditions suit a 16–19% Cr ferritic stainless steel and when 304/316/439/444 or duplex grades are not preferred.

Typical applications may include:
Heat exchanger tubes for general service
Condenser tubes
Chemical and petrochemical tubing
Nitric acid and organic acid service
Food, water, and general industrial tubing
Automotive exhaust and furnace parts
Welded components requiring titanium stabilization

It's genuine 321H — titanium-stabilized, so no worries about sensitization or intergranular corrosion during welding. Our welder said it welded nicely with no cracking.

Been running about 6 months now in cyclic service. No leaks, no failures. Heat transfer still where it should be.

We checked a few before installation — wall thickness consistent, roundness good. Welded in without problems.
