OVERVIEW
439 STAINLESS STEEL
439 is a titanium stabilized, 18 percent chromium alloy that is a ferritic stainless steel designed to resist corrosion in a variety of oxidizing environments from fresh water to boiling acids.439 stainless steel does not require annealing after welding to restore ductility or provide intergranular corrosion resistance.This type of steel is often used in applications that require high formability, such as the automotive industry.
Excellent resistance to stress corrosion cracking, good weldability, high thermal conductivity and low thermal expansion characteristics make Type 439 stainless steel an ideal consideration for many applications.

-
What is the main application of 439 stainless steel ?
>439 stainless steel is widely used in automotive exhaust systems, heat exchangers and other fields due to its excellent corrosion resistance, heat resistance, and weldability.
-
What is the difference between 439 and 304 stainless steel?
>The distinction between 439 and 304 stainless steel lies in their composition, corrosion resistance, heat tolerance, and cost. 439 steel, containing 16-18% chromium and 0.5-1.5% titanium, offers enhanced corrosion resistance due to its higher chromium content, compared to 304’s 18-20% chromium and 8-10.5% nickel composition. While both exhibit excellent corrosion resistance, 439’s superior chromium levels give it an edge, especially in high-temperature settings, making it suitable for uses like automotive exhausts where heat resistance is crucial. In terms of pricing, 439 typically comes at a higher cost, attributed to its specialized properties and higher chromium content, making it a more premium option compared to the widely used 304 stainless steel.
-
What is the difference between 439 and 409 stainless steel?
>439 stainless steel, with its 16-18% chromium content and 0.5-1.5% titanium, is engineered for enhanced corrosion resistance and is particularly adept at handling higher temperature applications.
409 stainless steel, typically featuring a slightly lower chromium level and lacking titanium, provides adequate corrosion and heat resistance but doesn't match the heightened performance of 439. Although both are popular in automotive exhaust systems, 439 stands out for its superior corrosion resistance. -
What is the MOQ?
>Our MOQ for regular sizes is usually 5 tons.
-
Do you have secondary 439 stainless steel material?
>No,we only provide prime ss 439 stainless steel sheet and coil.
-
How long is the delivery time?
>Trial orders can be delivered within a week. For regular orders, it takes 7-30 days roughly.
-
What is the Mill of Origin for your 439 stainless steel coil and sheet?
>TISCO, Posco, Baosteel, Runxin, Aoxing, etc
-
Can you provide custom 439 stainless steel?
>Yes, we can offer 439 cut to size customization services for our 439 products based on your specific requirements, from thickness, width to surface treatment. Just let us know your application.
