Spring
A spring is an elastic component capable of undergoing elastic deformation and returning to its original shape. Carbon steel, with excellent strength and hardness, can withstand high levels of stress and load, and is easy to process. Therefore, it is the optimal choice for spring suppliers and carbon steel suppliers. The most commonly used steel are S50C, S65C, SK85, 1065, 1085, and the SUP series.
