1. Optical properties:

After being polished, the surface has a high finish and metallic luster.

2. Machinability:

It is relatively moderate, but slightly more difficult to cut than ordinary carbon steel.

3. Forgeability:

Good forging performance allows forging into different shapes.

4. Stampability:

It has good stamping performance and is suitable for manufacturing various stamping parts.

5. Weldability:

Excellent welding performance, suitable for a variety of welding processes such as argon arc welding, manual arc welding, etc.

Chemical properties:

1. Elemental composition and stability:

The main chemical elements include iron, chromium, nickel, etc., and also contain a small amount of carbon, manganese, silicon, phosphorus, sulfur and other elements. These elements remain relatively stable under a certain proportion.

2. Antioxidant properties:

In high-temperature environments (up to 800-900 ° C), it can resist a certain degree of oxidation, forming a relatively dense oxide scale and preventing further oxidation to a certain extent. It is not easy to rust when left in an atmospheric environment for a long time.

3. Passivation characteristics:

After contact with oxidizing medium, a passivation film is easily formed on the surface, which changes the surface electrode potential and improves its corrosion resistance.

4. Surface chemical properties:

A variety of surface chemical treatments, such as electroless plating, can be performed to modify its surface chemical properties and appearance.
