  3. Metal Alloy Machinability Ratings | All Metals & Forge

    The American Iron and Steel Institute (AISI) determined the machinability ratings for a wide variety of materials. They determined this by running turning tests at 180 surface ft/min (sfpm). The AISI then arbitrarily assigned 160 Brinell B-1112 steel a machinability rating of 100%.

  4. Machinable, heat treated 4140 - The Home Machinist!

    It is my understanding that 4140 steel A. Can be had in a heat treated grade that is still "machinable" albeit possibly requiring carbide tooling for best results. B. Can be had annealed and then be heat treated after machining. C.

  5. Machining 4140 | The Hobby-Machinist

    Hey all, I recently bought a 1.75"x4' piece of 4140 for a project of mine. This is the first time machining this alloy, and while cutting it the temperature of it got super hot. I was blown away how hot it got. Is this normal for this type of steel? Or was I turning it too fast?

  6. Metals Machinability - Engineering ToolBox

    Machinability depends on the physical properties and the cutting conditions of the material. Machinability can be expressed as a percentage or a normalized value. The American Iron and Steel Institute (AISI) has determined AISI No. 1112 carbon steel a machinability rating of 100%.

  7. AISI 4140 Chrome-Molybdenum High Tensile Steel

    AISI 4140 is a chromium-molybdenum alloy steel. The chromium content provides good hardness penetration, and the molybdenum content ensures uniform hardness and high strength. AISI 4140 chrome-molybdenum steel can be oil hardened to a relatively high level of hardness. The desirable properties of best 4140 steel machinability

  8. Machining 4130 (prehard or Annealed?)

    4130 has a machinability rating of about 35%, meaning your speed will be about 1/3 that of mild steel. Using carbide try about 100 SFPM and HSS about 30 SFPM. 38Rc is not a problem with carbide, might have to run slower. 4130 hardens about 1" deep so if you have cross sections exceeding that you best 4140 steel machinability

  9. machining 4140 | Engineers Edge Forum |

    Although there are several materials tougher and of which work harden more readily, it is a strong consideration while machining 4140 steel. One reason is because poor drilling methods (or with dull drills) may weld or embed protions of the drill itself into the work area. This creates a serious problem often resulting in the work being scraped.
