| Chemical Composition | 409 stainless steel usually contains about 11% chromium, which is a common alloying element in stainless steel materials. In addition, 409 stainless steel also contains small amounts of elements such as molybdenum, manganese, silicon, copper, nitrogen and carbon. The addition of these elements can improve the performance of stainless steel. | |||
| Brief Introdction | 409 stainless steel have good processability, good weldability, good oxidation resistance at high temperature, it's able to withstand the temperature range from room temperature to 575 degrees. | |||
1. Good corrosion resistance: 409 stainless steel coil for sale has good corrosion resistance to most acid, alkali, salt and other corrosive media at room temperature, and maintains stable corrosion resistance at high temperatures.
2. Good high temperature strength: 409 stainless steel has good high temperature strength and thermal stability, and can withstand corrosion and oxidation at high temperature.
3. Good processing performance: 409 stainless steel is easy to cut, weld and form, and has low cost. It is a widely used material.
4. Low cost: Compared with other stainless steels, the cost of 409 stainless steel is lower, so it is an economical choice in some applications that require corrosion resistance.
5. Low tensile strength and ductility: Compared with other stainless steels, 409 stainless steel has lower tensile strength and ductility, which means that it is not suitable for applications with high strength requirements.
6. It is easy to produce surface scratches: the surface of 409 stainless steel is relatively soft, and it is easy to produce surface scratches and wear.
1. 2B Steel Finish: The 2B Finish is widely used and is known for its smooth and reflective surface.
2. BA Finish: The BA Finish is a highly reflective, mirror-like finish.
3. No.4 Finish: No.4 Finish Stainless Steel has a brushed appearance and offers a less reflective, duller surface.
4. Hairline Finish: Anti-fingerprint stainless steel features a subtle and decorative effect with its long, narrow line pattern.
5. The Embossed Finish adds texture to the surface with raised patterns, creating a decorative effect.
6. The Etched Finish is achieved through acid etching, resulting in a patterned surface and providing a decorative finish.
1. Automobile exhaust system: The high temperature strength and corrosion resistance of 409 stainless steel make it a commonly used material in the manufacture of automobile exhaust systems.
2. Gas burner: 409 stainless steel has good high temperature strength and thermal stability, making it a common material in gas burners.
3. Garbage incinerator: The high temperature strength and corrosion resistance of 409 stainless steel make it a common material in garbage incinerators.
4. Household appliances: 409 stainless steel is often used to manufacture inner tanks and shells of household appliances such as washing machine drums, dishwasher drums, ovens and microwave ovens.
5. Construction: 409 stainless steel can be used to manufacture various building components, such as railings, doors and windows, ceilings, etc.
