439 Stainless Steel Tube
A ferritic stainless steel tube specially formulated and processed for the harshest environments.
Each Type 439 Stainless Steel Tube begins with special attention to chemical composition and processing to create a stainless steel with optimum formability as well as extreme oxidation, corrosion and heat resistance.
A ferritic stainless steel tube, type 439 outperforms both type 409 and 436 in oxidation and corrosion resistance in the most-demanding environments. Type 439 stainless steel tube withstands temperatures upwards of 1700˚F (927˚C), exceeding the limits of both types 409 and 436. Its chemical composition gives type 436 ideal formability for difficult-to-form systems and components.
Type 439 stainless steel tube withstands temperatures upwards of 1700˚F (927˚C), exceeding the limits of both types 409 and 436.
