🔵 Description:

 

439 stainless steel plate is a ferritic stainless steel. This stainless steel enhances the corrosion resistance and oxidation resistance of the material by adding titanium (Ti) as a stabilizing element, and improves its high temperature performance and resistance to intergranular corrosion. 439 stainless steel belongs to low carbon steel with extremely low nickel content, so the cost is relatively low, and it is a material choice with both economical and high performance.

🔵 Main characteristics of 439 stainless steel:

 

▪Strong Corrosion Resistance:

439 stainless steel has a high chromium content (17%-18%), which can form a stable passivation film, effectively resist oxidation and corrosion in a hot and humid environment, especially in a chlorine-containing environment.

 

▪High Temperature Oxidation Resistance:

In a high temperature environment, 439 stainless steel can maintain excellent structure and strength.

 

▪Intergranular Corrosion Resistance:

The addition of titanium can effectively prevent the precipitation of chromium carbide at the grain boundary, thereby improving the ability to resist intergranular corrosion, which makes 439 stainless steel show better stability after welding.

 

▪Stable Chemical Composition:

The chromium content of 439 stainless steel is usually between 17%-18%. The addition of titanium effectively prevents the occurrence of intergranular corrosion and enhances the stability of the welding area.

 

🔵 Applications:

 

▪Automotive industry: exhaust pipes, catalytic converter housings and other parts.

▪Heat exchangers: heat exchange equipment in boilers, water heaters and air conditioning systems.

▪Building decoration: roof panels, building exterior walls and decorative panels.

▪Food industry: food processing equipment, tanks and storage containers.

▪Chemical industry: corrosion-resistant pipes, storage tanks and other equipment.
