CASTCUTDownload CASTCUT Spec sheet
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.
- 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).
- 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.
Reverse polarity (DCEP), maintain tight arc peen after 2-3 inch bead.
Reverse Polarity (DCEP)
Shielding Gas: 75% Argon – 25% Co2
Peen after 2-3 inch bead
Alloy Cored Wire Size
- 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.
