C100S Spring Steel Strip is made from high-carbon steel, perfect for making precise springs and tough machine parts. It's C100S grade, known for its springiness, toughness, and reliable performance, even with constant use. Our strips meet ASTM A228, JIS G 3521, and DIN EN 10132-2 standards, so you know you're getting quality that works in lots of things.
The steel mix is carefully controlled, usually with 0.95-1.05% carbon, around 0.25% manganese, and hardly any junk. This means it's really hard and strong. We make it using modern cold rolling and tempering, which gives it a consistent structure that makes it even more stable. So, it's a good pick when you need something that can bend a lot or handle high stress.

Features & Advantages
Corrosion and oxidation resistance
High-carbon steel can rust, but our special methods for tempering and treating the surface help cut down on corrosion. This means parts last longer, even when things get a bit corrosive.
High Strength and Mechanical Stability
This stuff is strong and bendy, so springs and parts work the same for a long time, which means they're less likely to break or bend out of shape.
Excellent formability and machinability.
C100S Spring Strip is easy to cut, bend, and shape without losing its strength. Because it's easy to weld, it can be used in tricky builds, which means it works for lots of different production needs.
