Additional Information on Stainless Steel Alloy 409
Stainless steel 409 is one of the various types of steel we sell here at Elgiloy Specialty Metals Hampshire Mill. If 409 stainless steel alloy is what you are looking for, we have got you covered.
We work with many industries including automotive, petrol-chemical, medical, various consumer product manufacturers, aerospace, housing, HVAC, and distribution. So, as you can see, there is a good chance we can help you.
We can provide for multiple stainless steel needs including stainless steel 347, stainless steel 305, and stainless steel 302. We can also help you to determine the right type of stainless steel for your specific needs and industry.
Stainless steel alloy 409 is a smart choice when budget matters. It is a low-cost option compared to other choices. When it comes to strength at high temperatures and the ability to resist oxidation, 409 stainless steel alloy does better than a Carbon steel.
This type of stainless steel alloy is often used, for example, in the coal industry in a variety of applications. 409 stainless steel alloy can be used for things such as chutes, bunkers, hoppers, screen pans, bin feeders, bins as well as discharge chutes, slurry pipelines, and silos.
Stainless steel alloy remains cost-effective while being corrosion-resistant and abrasion-resistant. It is a ferritic stainless steel alloy and can be welded in two ways. It can be welded by using both the resistance and fusion techniques.
Many industries can make the most of 409 stainless steel alloy besides the coal industry. These would include the automotive industry where you will see this specific type of stainless steel alloy used in manufacturing exhaust systems, exhaust pipes, fuel filters, mufflers, tailpipes, catalytic converters, and heat exchangers. You will also see this specific material in agricultural spreaders and many consumer products.
There are numerous chemical elements in 409 stainless steel. In addition to iron, to give it the correct balance, 409 contains:
- Nitrogen, at .015%
- Carbon at .02%
- Titanium, at .2%
- Phosphorus at .02%
- Nickel at .85%
- Sulfur at .004%
- Chromium at 11%
- Silicon at .35%, and
- Manganese at .7%.
Alloy 409 stainless steel can be used in a variety of ways including stamping, bending, drawing, cutting and welding. You will find it performs better in a dryer air as opposed to a moist environment.
