Agree with @ericc, if the material you have is equivalent to 4140, it is an oil-hardening steel with a maximum hardness of about Rc 48-50. Pre-hardened 4140 will be Rc 28-32. AISI 4140 alloy steel is heated at 845°C (1550°F) followed by quenching in oil. Before hardening, it can be normalized by heating it at 913°C (1675°F) for a

A wide variety of 4140 steel plate options are available to you, such as ship plate, container Laser nitriding of AISI 4340 steel - ScienceDirectJan 01, 1988 · Experiment Specimens in the form of circular plates, 23 mm in diameter and 5 ram in thickness, were cut from annealed AISI 4340 low alloy steel (C=0.38%, Cr=0.8%, Ni=1.55% and Mo=0,53%). After cutting, the specimens were heated to 830, and thereafter quenched in oil, and annealed, reaching a hardness of 41-42 Rc. Machining 4140 The Hobby-MachinistFeb 06, 2018 · Cutting speed for 4140 is about 50 fpm for HSS. So:4 times 50 divide by 2 gives us 100 rpm. I used flooded coolant, really makes a difference in tool life and surface finish. Grind in a good chip breaker to roll the chips and avoid long stringy razor blades. Safer and
at the present time, these alloy steels can be classied into three main categories:molybde-num steels, chromium steels, and triple-alloyed (Mo Cr Ni) steels. Table 6.3 lists a select num-ber of the low-alloy steels grouped into these three categories. A complete listing of the low-alloy AISI steel compositions can be found in Ref 6.1 to 6.3. eFunda:Properties of Alloy Steel AISI 4140eFunda:Properties of Alloy Steel AISI 4140. Home.
