The increasing use of ferritic stainless steels (AISI 409, 439, 436 and 441) in automotive exhaust systems, especially for manifolds and catalytic converter canning, has led the authors to develop
409 stainless is a metal designed primarily for the automotive exhaust industry, although it has been used successfully in other industrial applications. It combines good elevated temperature corrosion resistance and medium strength, good formability and inexpensive overall cost. On the other hand, 304 stainless is one of the oldest variants of 409 Stainless Steel Supplier Stainless Shapes, Inc.Stainless Shapes is an experienced 409 Stainless Steel supplier. 409 SS is a general purpose ferritic stainless steel. It is one of the most common stainless objects in Automobiles because of its low cost and high resistance to average strain and heat. There is also a higher grade version of stainless steel 409 known as SS 439
409 is the perfect grade stainless steel to be used in automotive applications where visual appeal is not a top priority. For this reason and for its durability to gas corrosion, 409 is most commonly used in truck exhaust systems, agricultural equipment, and heat and gas turbine exhaust silencers. 439 Stainless Steel Tubing Middletown Tube WorksType 439 stainless steel tube withstands temperatures upwards of 1700F (927C), exceeding the limits of both types 409 and 436. Resistant to wet, corrosive environments and possessing excellent formability makes type 439 stainless steel tube well-suited for automotive exhaust applications, especially when faced with high temperatures or
Type 439 is a stabilized ferritic stainless steel (Chromium content 17.0 min, 19.0 max.) with a higher Chromium (Cr) content than Type 409, which offers improved corrosion resistance. T439 is stabilized with a titanium (Ti) addition, which results in good weldability. The alloy resists intergranular corrosion and stress corrosion cracking.

Addressing Welding Challenges with 400-Series Stainless Jul 01, 2018 · Martin Denault Technical Manager Addressing Welding Challenges with 400-Series Stainless Steel July 1, 2018. The 400-series ferritic stainless alloys (409, 430, 439 and 444) are used for exhaust systems, mufflers, catalytic converters, water heaters and tanks, furnace shells, heat exchangers, kitchen equipment, and other equipment requiring corrosion resistance at elevated
Description:Type 441 Stainless Steel is a ferritic stainless steel which provides good high-temperature strength (exceeding that of Types 409 and 439 Stainless Steels) plus good corrosion resistance in many exhaust gas environments (equivalent to Type 439 and 18 Cr-Cb Stainless Steels). . Ferritic steels are not inherently strong at elevated temperatures, but columbium additions coupled with Reference - Stainless Steel Tubing & Tubetech.This grade of ferritic stainless steel exhibits good high temperature strength, exceeding that of the 409 and the 439 grades. Cyclic high temperature oxidation resistance is very good, while overall corrosion resistance is similar to that of the 18% chromium, ferritic grades. 441 stainless steel is used in automotive and truck applications
An Introduction to 409 Stainless Steel Slitting on San Antonio. Grade 409 is a ferritic stainless steel type that offers decent mechanical properties along with higher temperature resistance. In most cases, it is considered as a chromium stainless steel in applications that demand a higher level of weldability.

Type 439 has good weldability due to titanium stabilization and has excellent resistance to stress corrosion cracking. Type 439 outperforms Type 409 in both oxidation and corrosion resistance and typical applications include tubular manifolds and exhaust system components. Stainless Steels Welding Guide - Lincoln ElectricSTAINLESS STEELS Austenitic stainless steels include the 200 and 300 series of which type 304 is the most common. The primary alloying additions are chromium and nickel. Ferritic stainless steels are non-hardenable Fe-Cr alloys. Types 405, 409, 430, 422 and 446 are representative of this group. Martensitic stainless steels are similar in
Dec 21, 2010 · The difference between the types of stainless steel is the amount of chromium and nickel found in each. 304 stainless steel contains a much higher percentage of chromium and nickel. This makes it much more resistant to rust. 409 stainless steel is still more rust-resistant than Aluminized Steel. However, neither type of metal is 100% rust-proof. Which stainless rod needed to weld 409 stainless?Oct 21, 2008 · The 308 is cheaper then the 309 and 316. You can actually use any one of those you want. We use ER308L on our 3cr12 stainless bodies and 3cr12 is basically the same thing as 409 stainless. Do a search on cromegaurd 3cr12 stainless and it will tell you that it derived from 409 stainless and you can use 308,309, or 316 to weld it.
Alro Steel stocks 409, 439 and 430 Stainless Sheet grades 439 Stainless Steel Sheet 439 stainless steel has good corrosion resistance due to its 17% minimum chromium content. 439 can be formed using a wide range of roll forming or mild stretch bending operations as well as more common drawing and bending operations.
