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.
