The designation 20mm typically refers to the wire diameter or the outer diameter of the spring in millimeters, although it can also denote different dimensions depending on context. Depending on the specific requirements, the 20mm compression spring can be manufactured using various materials—most commonly stainless steel, carbon steel, or alloy steel. These materials are chosen for their strength, durability, and resistance to fatigue, which are critical in ensuring the longevity of the spring.
