TP439 , UNS S43035 Stainless Steel Tube And Pipe For Feedwater Heater And Condenser
TP439 ( UNS S43035 , EN 1.4510, DIN X3CrTi17 ) is a titanium-stabilized 17% chromium ferritic
stainless steel with improved corrosion resistance, formability, and weldability compared to 430.
TP439 is a medium-chromium ferritic stainless steel, which can be used in many mildly corrosive environments.
Because of its titanium alloying, TP439 stainless steel can be welded in all dimensions without becoming
susceptible to intergranular corrosion. It is possible to use TP439 stainless steel at elevated temperatures,
for instance the cold end of automotive exhaust systems.
Characteristics
- More oxidation resistant than type 409
- Good weldability and resistance to intergranular corrosion
- More corrosion resistant than type 409 stainless
- Non hardening
- Formable
Typical applications
- Automotive exhaust systems
- Sugar industry equipment
- Household appliances
