- Descrição
SS 409 plate is a ferritic stainless steel plate widely used in applications requiring good oxidation resistance, resistência ao calor, and cost-effective corrosion protection. Although the keyword includes “price,” the value of SS 409 plate is mainly influenced by its material composition, grossura, acabamento superficial, e requisitos de processamento. Comparado com 304 aço inoxidável, 409 offers lower chromium content but better economy for structural and high-temperature applications.
O que é SS 409 Placa?
SS 409 plate is a chromium-based ferritic stainless steel that contains low nickel and added titanium for improved stabilization. It is commonly used in environments where moderate corrosion resistance and high-temperature durability are required. Devido ao seu design de liga balanceado, 409 stainless steel is frequently chosen for automotive exhaust systems, industrial heat equipment, e aplicações estruturais.
This grade is magnetic and cannot be hardened by heat treatment, but it provides excellent weldability and good resistance to oxidation.
Composição Química do SS 409 Placa
The alloy composition of SS 409 plate gives it good thermal stability and resistance to atmospheric corrosion.

Principais características de desempenho
Resistência ao Calor
SS 409 plate offers good oxidation resistance at elevated temperatures and is commonly used in continuous service up to approximately 675°C.
Resistência à corrosão
The material provides adequate resistance to atmospheric corrosion, exhaust gases, and mild industrial environments. It performs better than carbon steel but lower than 304 stainless steel in humid or chloride-rich conditions.
Soldabilidade
Because of titanium stabilization, SS 409 plate has good weldability and is often processed by laser cutting, soldagem, e formando.
Eficiência de custos
Due to its low nickel content, SS 409 is considered a more economical stainless steel grade for applications that do not require premium corrosion resistance.
