Relying on its superior tensile and yield strengths, 1075 spring steel is positioned as the essential material for spring, coil, and shim manufacturing.
Our laser cut 1075 Blue Tempered Spring Steel (also known as Scaleless Blue Tempered Steel) is perfect for spring applications or where stiffness is required with minimal thickness.
1075 isn’t just for springs, clamps, and coils. It’s often used in blade-making as well. It’s able to hold its edge well and is receptive to sharpening. It also has much better workability and toughness than something with a higher carbon count (like 1095).
