Steel Shot S330

　　1. Specifications and Features

　　Diameter: S330 means the diameter of the steel shot is about 0.84 mm (about 0.033 inches).

　　Hardness: Usually between 40-50 HRC (Rockwell hardness), with good wear resistance and impact resistance.

　　Material: Usually made of high carbon steel, quenched and tempered to ensure its hardness and toughness.

　　2. Application Areas

　　Surface Cleaning: Used to remove scale, rust, oil stains, etc. on the metal surface.

　　Surface Strengthening: Through shot peening, the fatigue strength and stress corrosion resistance of metal parts are improved.

　　Casting Cleaning: Used to clean sand and burrs on the surface of castings.

　　Coating Pretreatment: Before spraying or painting, it is used to increase the roughness of the metal surface and improve the adhesion of the coating.

　　3. Advantages

　　Efficient cleaning: It can quickly clean the metal surface and improve work efficiency.

　　Long life: Due to high hardness and good wear resistance, it has a long service life.

　　Environmental protection: can be recycled to reduce waste generation.

　　4. Precautions

　　Choose the appropriate specifications: select the appropriate steel shot specifications according to the material and surface requirements of the workpiece to be processed.

　　Equipment maintenance: regularly check the wear of the shot peening equipment to ensure uniform spraying of the steel shot.

　　Safety protection: wear protective equipment during operation to avoid damage caused by splashing steel shots.

　　5. Storage and maintenance

　　Dry environment: Steel shots should be stored in a dry environment to prevent moisture and rust.

　　Avoid pollution: avoid mixing with other impurities and keep the steel shots clean.

　　Steel shot S330 is widely used in the automotive, aerospace, shipbuilding, machinery manufacturing and other industries, and is one of the indispensable materials in the surface treatment process.
