Mild Steel Shim Stock
Low carbon mild steel shim stock is cold rolled to achieve its hardness of 165VPN (min) which is ideal for shims, gaskets and also suitable for drawing or forming. Low carbon mild steel cannot be hardened except by cold working because their carbon content is too low for significant heat treatment reaction to take place. However, they can be case hardened to give a harder surface. We also offer 316 stainless steel shim kits, brass shim sheets, 304 stainless steel pre-cut shims, and other shim kits.
