Maybe back it down 10% You know how people tell you to go max revs and feed as hard as you can on aluminum. That's kind of what happens with an annealed 4140 or 4340.. My magic # in the soft stuff has been .070 step over with a 1/2" 700-900 sfm and feed the heck out of it.. .007+ a tooth..

Shooters' ForumApr 14, 2020 · This is the same steel that is used for machine gun (and more recently rifle) barrels for the military since WWII. The alloy was intended to be a bit more resistant to heat erosion than (at the time) standard 4140 steel. It is often referred to as 'machine gun steel,' or ChromeMoly Vanadium.
General characteristics of 4140 Alloy Steel. AISI or SAE 4130 grade is a low-alloy steel containing chromium and molybdenum as strengthening agents. Its chemical composition is as follows. AISI/SAE 4140 grade is a versatile alloy with good atmospheric corrosion resistance and reasonable strength. AISI 4140 Chrome-Molybdenum High Tensile SteelAISI 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. AISI/SAE Steel and Alloy - Designation SystemAISI/SAE steel numbers are indicated below. AISI - American Iron and Steel Institute; SAE - Society of Automotive Engineers; Alloy steels and carbon steels can be designated with specific grades by a four-digit AISE/SAE numerical index system. The system is based on the chemical compositions of the steels and alloys. Example AISI/SAE No. 1020
A high speed steel "G" drill is being used prior to reaming a 3/8 hole on a piece of 1095 steel with a brinnel hardness of 300. Calculate the RPM setting to perform the drilling and reaming operations. Cutting Speed = 40 (fpm) Diameter of Cutter = 0.3701 (G drill) Half the speed for reaming would be = 432 / 2 = 216 RPM for reaming. Drilling Speeds and Feeds 2019 [RPM, Calculator, Chart The number one factor affecting twist drill performance is chip formation and evacuation. The deeper the hole, the more likely chips can jam. mill a flat spot for the drill to get started on before attempting to drill. G-Wizard recommends either a split or notched point with a 135 degree angle for 300 series stainless steel Easy Test Needed To Tell 4140 From Carbon Steel - Metal Jul 15, 2003 · Beside spark testing and chemical spot checking, we also used eddy current testing to differentiate 4140 and 4340. When portable XRF analyzers became available to us in 1971, that became the primary method to separate "mixed" alloy steels - except for carbon content.
