Stainless Steel 409 Channel

Stainless Steel 409 Channel comes in the form of a hot rolled or cold formed stainless steel structural shape, which is manufactured in Grade 409 stainless steel and commonly abbreviated as (UNS S40900). It is also a ferritic alloy and has 11-13 chromium with minimum amounts of some other elements such as titanium which is added to improve weld ability and resistance of oxidation.

Storage of utility steel 409, unlike austenitic stainless steels (such as 304 or 316), has lower amounts of nickel, as well as is regarded as a utility-grade stainless steel, suitable circumstances where resistance to corrosion is much less of a concern than thermal effectiveness and expenditure limitation. Titanium stabilization in 409 prevents precipitation of carbides in the grain boundaries so that it easily weld able and corrosion-resistant to some extent.

• Corrosion Resistance: Has a good effect against exhaust gas and atmospheric corrosion particularly around mild to moderate corrosive conditions.
• Heat Resistance: It features well in hot-temperature areas to the extent of 675C, continuous usage, or to 815C intermittently, which is most suited in cars and other heat use.
• Mechanical Strength: SS 409 Channel has moderate structural mechanical load with its tensile strength of about 380450 MPa.
• Weld ability: Great weld ability with titanium stabilization so that no chances of intergranular corrosion during the welding process.
• Formability: Has good ductility and hence it is easily formed into channels, angles, and other structural components.

• Automotive Industry: Most often used in exhaust manifolds, mufflers and tail pipes where hot exhaust gas resistance is vital.
• Construction: Utilized in building structures, shoring/support and building decoration in zones that are not over and above subjected to hard aggressive chemicals.
• Manufacturing: Used in industrial ventilation systems, tubing supports and furnace casings.
• Agricultural Equipment: Applied in structural frames, enclosures and brackets where corrosion resistance is required at cost effective prices.
• Railway and Transport: SS 409 It is used in the undercarriage supports and in heat shields because of its ability to be welded, and its durability.

• Economical: High nickel and alloy content result in keeping the price of material down and pass on performance elements that are important.
• Thermal Stability: Stays strong, yet retains its shape in times of continuous exposure to great heat, most suitable in exhaust and furnace conditions.
• Good Weld ability and Fabrication: Titanium stabilization allows an easy welding process without post-weld heat treatment making manufacturing processes easy.
• Moderate Corrosion Resistance: Corrosion resistance is suitable to several industrial and automotive applications where a high degree is not a priority.

Stainless Steel 409 Channel is a low-cost, fire- resistant structural product suitable in automotive, construction and industrial industries. Although it is not as stable to corrosion as stainless steel of higher grades, its cost and thermal stability combined with ease of fabrication, makes it a leading stainless steel in low-cost stressful heat applications.
