What is AISI 409 Stainless Steel Round Bars?
409 stainless steel bar belongs to ferritic stainless steel. It is an economical material with low carbon content (C≤0.08%) and moderate chromium content (11.0-12.5%) in 400 series stainless steel. Its outstanding features are low cost and good processability. It also has good high temperature oxidation resistance and medium corrosion resistance. It is widely used in industrial fields that do not require high corrosion resistance but need to balance cost and performance.

Why is the price of 409 stainless steel bar cheap?
Because it does not contain nickel, its price can be reduced by 30% - 40% compared with 304 stainless steel. In mass production scenarios, it can significantly reduce costs and bring higher economic benefits.
409 stainless steel round bar has good cold formability and can easily adapt to various processing processes such as stamping and bending. In terms of welding, ER409L welding wire is recommended. No preheating is required during welding, and no heat treatment is required after welding, which improves production efficiency.
In a long-term use environment below 650°C, a dense oxide film can be formed on the surface of 409 stainless steel, which has good anti-peeling ability. It can replace some heat-resistant steel and be used in medium and low temperature conditions. It is an ideal processing material for products such as automotive parts and building decorations.
