Outstanding ease in Flame Hardening

  • Will fully harden is air without a water quench.
  • Very forgiving material – low operator sensitivity.
  • Double the hardenability of SAE J435c/0050A.

Deep uniform case

  • 3/16″ to 3/8″ in normal practice.
  • Will attain 1/2″ if necessary.

High uniform hardness

  • 63-64 Rc as quenched.
  • 59-61 Rc following 300° F temper.
  • May be tempered using a torch and “Tempilstiks” (temperature indicating crayons).

Strong rigid base structure

  • Castings up to 4″ approximate cross sections are supplied in the heat treated and double tempered condition at 32-35 Rc and 140 to 160 KSI tensile and compressive strength. This is a 50% approximate increase vs. SAE J435c/0050A (at 90 to 105 KSI tensile and compressive strength).

Very low distortion during Flame Hardening

  • High strength, low transformation temperature and resulting structure contribute to the non-distorting properties.

Flame Hardening

  • Cast Cut® #1 is designed for Flame Hardening only.
  • Flame Hardening Temperature 1600° F ± 50° F (preheating not necessary).
  • Cast Cut® #1 responds best when allowed to air cool.
  • When possible, temper at 300/350° F.
  • This may be done is a furnace or with a torch and a “Tempilstik” (temperature indicating crayon).

Outstanding Weldability

  • Cast Cut® #1 coated electrodes and alloy cored wire offer exceptional advantages.
  • Cast Cut® #1 welding materials result in a weld deposit chemistry that is identical to the base material.
  • The as welded hardness is 55-59 Rc and may be tempered at 1150° F to approximately 36 Rc for machining.
  • When Flame Hardened, the Cast Cut® #1 weld deposit will react the same as the base material.
  • The weld deposits will be nearly identical both cosmetically and in terms of chemistry and hardness.
  • In an emergency situation, Cast Cut® #1 may be repair welded cold, in the press, using any available tool steel rod. The weld deposits will not be Flame Hardenable.

  • When necessary, Cast Cut® #1 may be repair welded in the press using Cast Cut® #1 coated electrodes. The as welded hardness will be 55-59 Rc.
  • The recommended procedure is to pre heat at 300-350° F, weld and temper the entire section at 1150° F. This may be done in a furnace or with a torch and a “Tempilstik” (Temperature indicating crayon).
  • Follow machining and refitting, the section may be re-Flame Hardened. The weld deposit and base metal will react identically. The result will be a “new” section.


  • Best results are obtained with the use of “Chemdraw 1717” cutting oil from:
    • Brighton Laboratories
    • (810) 632-3045
  • and “Rission #888” penetrating lubricating fluid from:
    • Rission Group, Inc.
    • (313) 581-2620
