Stainless Steel Alloy 409

Stainless steel alloy 409 has the ability to maintain strength and resist corrosion when exposed to high temperatures. It is also an easy stainless steel to form, yet is very cost effective.

While machining can be done with annealing, it does tend to produce chips and a heavy build-up. It is an easily formed stainless steel, often compared to soft carbon steel in its ductility during the anneal condition.

Stainless steel alloy 409 does respond well to cold drawing. It also does well with hot working at temperatures over 1600 F. This steel alloy responds well to welding when the SMA, GMA and GTA processes are used.

When hot working alloy 409, 1900 to 2050 F is the ideal temperature for working. Do avoid soaking it while it remains in that temperature range. It is also best to avoid working it in temperatures below the 1500 F mark.

If the material requires soaking, the temperature should be maintained between 1200 to 1400 F degrees, not lower. Also air cooling is the preferred method of cooling for annealing.

Highly prized by the automotive industry, stainless steel alloy 409 is most often used for mufflers, tailpipes and catalytic converters. It is also used in hangers and structural supports, diamond tread plate, farm equipment and shipping containers.
