Air-hardening Steels






Category: FURNACES

These steels are recommended for boring,
turning and planing where the cost of high-speed seems excessive.
They are also recommended for hard wood knives, for roughing and
finishing bronze and brass, and for hot bolt forging dies. This
steel cannot be cut or punched cold but can be shaped and ground
on abrasive wheels of various kinds.

It should be heated slowly and evenly for forging and kept as evenly
heated at a bright red as possible. It should not be forged after
it cools to a dark red.

After the tool is made, heat it again to a bright red and lay it
down to cool in a dry place or it can be cooled in a cold, dry
air blast. Water must be kept away from it while it is hot.
