What's the difference between 4140 and 4145 mod steel?
It is a heat treatable alloy steel that contains nominally .45% Carbon, with Chromium and Molybdenum as the primary hardening elements. As compared to 4140, the 4145 mod grade has higher levels of Chromium and Molybdenum, which will provide much deeper hardening into the steel after austentizing, quenching and tempering.See all results for this questionWhat should I know about machining 4140 shafts?Cutting speed in FPM, calculate proper RPM, use of HSS or Carbide, rigidity and horsepower of lathe, coolant, etc. Spent many an hour on a big 30 inch Monarch making 4140 shafts in a large job shop. The lathe had a 5 ton bridge crane over head with two hooks to give you an idea of the size of work pieces.

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%. The machinability rating is determined by measuring the weighed sae 4140 mod MachiningMaterials Machined - CNC IndustriesEach alloy has its own machining characteristics and its important to understand how each machines in order to get the best removal rates and best finishes.

Handbook: Everything You Should Know About 4140 Steel
Before 4140 steel is ready for use, it is usually subjected through these three processes; annealing hardening and tampering. The purpose of these processes is to enhance the physical and mechanical properties of this steel. 4140 steel is annealed at 872°C which is equivalent to 1600°F. After that, the steel is cooled in a furnace.Fushun AISI SAE 4130 Forged QT Machining Alloy Steel TubeAISI SAE 4140 alloy steel is a chromium molybdenum alloy steel specification widely used in general purpose high tensile steel for components, like axles, shafts, bolts, gears and other applications.
