Flat Key Ordinary Type/Quenching Type

Frequently asked questions about this product

1. Why are flat keys made of stainless steel magnetic?

During the cold processing of the material, due to stress, some austenite structural characteristics are changed to martensite and ferrite. As the deformation increases, the magnetism increases, so the product will have weak magnetism, and the magnetism varies with the deformation of the product.

2. How to prevent the flat key from rusting?

If you have requirements for rust prevention, please choose SUS304 material. Carbon steel material has not been surface treated, so it is easy to rust. It needs to be regularly applied with rust-proof oil for maintenance to extend the rust prevention time.

3. What is the difference between the standard and precision models of flat keys?

L size (length) tolerance accuracy range: precision model > standard model.

4. There are scratches on the appearance of the flat key

Product processing technology problem. The surface of the product has not been treated, so it is very easy to have scratches. This is a normal phenomenon and does not affect the correct use of the product.

5. What is the difference between the GB/T 1096-2003 standard and the GB/T 1096-1979 standard for flat keys?

There is a difference in the tolerance of the B dimension (width) between the two. The tolerance of the GB/T 1096-2003 standard is smaller and is suitable for more precise scenarios.
