Stainless Steel 409
While synonymous with automotive exhaust manufacturing, 409 stainless steel can be used in other applications beyond this standard use. At Arbor/Metals, Inc., we offer this ferritic, titanium-stabilized alloy for use in diverse industries and applications where durability and corrosion resistance matter. Take a look at the chemical composition and primary applications of alloy 409 before reaching out to place your standard and specialty alloy order with our team.
Industry Applications of 409 Stainless Steel Products
Alloy 409 heat-resistant stainless steel plate, bar stock, and wire are all frequently used in the automotive industry. However, many other products use stainless steel type 409 as well. Any of these common components can benefit from the unique properties of 409 alloy:
- Automotive mufflers, tailpipes, catalytic converters, and other exhaust components
- Farm equipment
- Transformer cases and structural supports
- Heat exchanger tubing and furnace components
Key Specifications of 409 Stainless Steel
Before manufacturing 409 stainless steel products, explore the specifications that set this alloy apart from common stainless steel grades. Alloy 409 offers the following advantages:
- Heat resistance: This alloy can withstand continuous temperatures up to 1,247 degrees Fahrenheit and intermittent temperatures up to 1,499 degrees Fahrenheit.
- Corrosion resistance: Both exhaust gas and general atmospheric corrosion are less likely with 409 steel than other alloys.
- Weldability: Once preheated to temperatures between 302 and 500 degrees Fahrenheit, this steel can be easily welded and annealed after welding.
- Machinability: Stamping, cold forming, and molding are all possible with this alloy.
