Description

[0002] Stainless steel is widely used due to its high strength, corrosion resistance and no rust.

For example, door handles, stair handrails, balcony railings, etc. are mostly made of stainless steel pipes, which are not only strong and durable, but also make the entire building look majestic. However, stainless steel itself has low hardness and is not wear-resistant. After long-term use, its surface is worn due to frequent contact with various objects and loses its original luster. In addition, hollow stainless steel pipes are prone to deformation after long-term stress, such as the steel pipes for hanging clothes in the closet.
