Heat Treating A2 Drill Rod

A2 is characterized by its excellent versatility non deforming properties toughness properties and dimensional stability in heat treatment.

Heat treating a2 drill rod. Aisi a2 tool steel is high carbon high alloy tool steel designed to have excellent wear resistance and toughness. A2 is intermediate in abrasion resistance between d2 high carbon and o1 oil hardening tool steel high chromium tool steel. Annealing heat at a rate not exceeding 400 f per hour 222 c per hour to 1425 1450 f 802 816 c and hold at temperature for 1 hour per inch 25 4mm of maximum thickness. The steel is composted of 1 percent carbon 3 percent silicon 6 percent manganese 5 3 percent chromium 1 1 percent molybdenum and 2 percent vanadium.

This widely used tool steel has low distortion in heat treatment good machinability good toughness for severe service high abrasion resistance and deep. A2 o1 w1 d2 s7 m2 v44. A2 tool steel shapes and sizes. A2 tool steel is a 5 chromium medium alloy cold work tool steel possessing sufficient hardenability to be air hardened to 60 rc surface hardness level with good depth of hardening.

W 1 rod has many general metalworking applications but does not provide a normal tool life equal to o 1 drill rod in diameters smaller than 1 2. A2 air hardening drill rod. A2 air hardening drill rod is a superior quality chromium alloy steel which has good machinability high compressive strength very good non deforming properties deep hardening and high dimensional stability after hardening and tempering.
