10B38 Steel Coil

What is 10B38 Steel?

10B38 Steel is a boron-treated medium-carbon steel alloy, designated by the American Iron and Steel Institute (AISI). Because this particular grade of steel has been treated with Boron, it has an increased hardenability – the depth to which it has been hardened following heat treatment. 10B38 Alloy Steel typically contains anywhere between 0.0005% to 0.003% Boron. This allows for consistent hardness, ductility, and less risk of fracture due to impact.

Siegal Steel offers 10B38 Steel Coil and Cut Lengths. We are experts in this particular grade of steel and can provide the specifications you need. We also offer processing services like oscillate winding and steel slitting. New to 10B38 and not sure it's right for your application?  Our experts would be happy to help!
