What is the advantage of ASTM A268 /ASME SA268 TP405 tubes ?
1. Improved Weldability
TP405 contains aluminum stabilizers, which reduce grain growth and hardening during welding.
It is less likely to crack after welding compared with TP410 and other ferritic steels.
2.Good Oxidation & Heat Resistance
With about 12% chromium, TP405 performs well in high-temperature service, such as exhaust and furnace applications.
Better resistance to scaling (surface oxidation) than TP410.
3. No Need for Post-Weld Heat Treatment
Unlike some other ferritic stainless steels, TP405 usually does not require annealing after welding, saving manufacturing cost and time.
4. Better High-Temperature Toughness
It maintains mechanical strength and toughness at elevated temperatures where TP410 becomes brittle.
5. Moderate Corrosion Resistance at Low Cost
Provides reasonable corrosion resistance for general industrial service.
Lower cost than austenitic grades like 304 or 316.
6. Magnetic & Dimensionally Stable
As a ferritic stainless steel, it is magnetic, has low thermal expansion, and good dimensional stability under heat cycling.
