1. Corrosion Resistance: Zerdans flat washers are made of 304 stainless steel, which is a kind of austenitic stainless steel with high corrosion resistance, suitable for all kinds of environments, especially wet or chemically corrosive occasions. 2. Heat Resistance: Compared with ordinary carbon steel, our 304 stainless steel flat washers have high heat resistance, suitable for high temperature working environment. 3. Non-magnetic: 304 stainless steel is non-magnetic or weakly magnetic in the annealed state, which is an important feature in equipment where magnetic interference needs to be avoided. 4. Strength and Toughness: 304 stainless steel has high strength and good toughness, capable of withstanding significant mechanical stress, making it suitable for use in environments with heavy loads. 5. Durability: Due to its corrosion resistance and strength, 304 stainless steel has a long service life, making it an ideal choice for long-term investment. Zerdans 304 Stainless Steel M5x15x1.2mm Flat washers are a standard mechanical part usually used in fasteners for protection and isolation.
