Keyed bars play a crucial role in many mechanical and industrial applications, ensuring power transmission and holding parts in place. In particular, A4 stainless steel keybars in accordance with DIN 6880 are known for their precision and robustness.
A keybar is a rectangular-shaped metal part inserted into corresponding grooves of two mechanical components to lock them together, thus allowing torque transmission and preventing relative movement between parts.
The DIN 6880 standard specifies the dimensions, tolerances and materials of keyed bars. This standard ensures that keybars are compatible and interchangeable, ensuring efficient installation and operation in mechanical systems.
A4 stainless steel offers an ideal combination of corrosion resistance, mechanical strength and acid resistance, making it a preferred choice for keyed bars. Unlike A2 stainless steel, A4 stainless steel is also resistant to chlorinated and saline environments, making it suitable for more corrosive environments.
The main difference between A2 and A4 stainless steel is their chemical composition and corrosion resistance. A4 stainless steel contains more chromium, nickel and sometimes molybdenum compared to A2 stainless steel, which gives it better resistance to chemical attacks, especially in aggressive marine or industrial environments.
