Indispensable In The Gun Shop For Parts, Tools & Repairs
One of the remarkable features of these tool steels is the low draw temperature to achieve maximum torsion impact strength. Most drawing can be done in a kitchen oven! Or you can easily make a small and efficient draw furnace on your bench using furnace brick, a simple heat element and a kitchen oven heat control. Draw all steel shown one hour.
W-1 WATER HARDENING DRILL ROD
Carbon - 1.00% Manganese - .40% Silicon - .20%
A fine-grained, commercial quality steel, W-1 can be used for tools, parts, dies or punches which require great hardness and a tough inner core for maximum strength. The sizes we carry should meet 99% of all requirements for pins in guns.
HARDENING: Heat the part to 1450° - 1500° F., or slightly higher (up to 1600° F.) if unusual depth of hardness is required. If a furnace is not available, use 1450° Tempilaq. Hold at this temperature for a few seconds, then quench in an 8% brine solution. Do not use fresh water! To make a brine solution: Add ¾ lb. (340 g) of rock salt to one gallon of water.
TEMPERING: Temper immediately. A one hour draw at the following temperatures will produce hardness on the Rockwell C scale as follows:
Rockwell C Hardness
|As Hardened ||66 - 67 |
|200° ||66 - 67 |
|300° ||64 - 65 |
|400° ||61 - 62 |
|500° ||58 - 59 |
|600° ||54 - 55 |
|700° ||50 - 51 |
|800° ||46 - 47 |
