Steel Shot S660

　　Steel Shot S660 is an abrasive commonly used for surface treatment, sandblasting and strengthening. Here are some key information about Steel S660:

　　1. Specifications

　　Grit size: S660 refers to the particle size of the steel shot, which is usually between 1.7mm and 2.0mm. The specific value may vary slightly depending on the manufacturer.

　　Hardness: The hardness of Steel Shot S660 is generally between 45-55 HRC (Rockwell hardness), which is suitable for a variety of surface treatment needs.

　　2. Applications

　　Surface cleaning: used to remove rust, oxide scale, old coating, etc. on the metal surface.

　　Surface strengthening: Shot peening is used to improve the fatigue strength of metal parts and extend their service life.

　　Surface pretreatment: Before painting, electroplating and other processes, it is used to increase surface roughness and improve coating adhesion.

　　3. Advantages

　　Durability: Steel Shot S660 has high durability and can be recycled many times.

　　High efficiency: The cleaning and strengthening effects are significant and suitable for mass production.

　　Environmental protection: It can be recycled and reused to reduce environmental pollution.

　　4. Precautions

　　Equipment selection: When using steel shot S660, you need to choose appropriate shot peening equipment to ensure the treatment effect and equipment life.

　　Operation safety: Operators should wear protective equipment to avoid inhaling dust and particulate matter.

　　5. Storage and maintenance

　　Dry environment: Steel shot S660 should be stored in a dry, well-ventilated environment to prevent moisture.

　　Regular inspection: Regularly check the particle size and hardness of the steel shot to ensure that it meets the requirements for use.

　　Steel shot S660 is widely used in the automotive, shipbuilding, aerospace, machinery manufacturing and other industries. It is an efficient and economical surface treatment material.
