SAE AISI 4140 Alloy Steel. SAE 4140 (AISI 4140 steel) is a Cr-Mo series (Chrome molybdenum series) low alloy steel, this material has high strength and hardenability, good toughness, small deformation during quenching, high creep strength and long-lasting strength at high temperature. 4140 Steel Uses. AISI SAE 4140 alloy steel can be made into round steel bar, flat & square steel bar, steel ...

AISI 4140 alloy steel can be tempered at 205 to 649°C (400 to 1200°F) depending upon the desired hardness level. The hardness of the steel can be increased if it has a lower tempering temperature. For example, a tensile strength of 225 ksi can be achieved by tempering at 316°C (600°F), and tensile strength of 130 ksi can be achieved by tempering at 538°C (1000°F).

Alibaba.com offers 35 crankshaft steel 4140 products. About 8% of these are steel round bars, 2% are machining. A wide variety of crankshaft steel 4140 options are available to you, such as jis, astm, and aisi.

In this study, a new magnetic field coupled deep cryogenic treatment (MDCT) is developed and its effect on wear resistance of AISI 4140 steel is investigated. Compared with wear resistance of untreatment (UT), wear resistance of MDCT increases by 29%. Wear resistance is inversely proportional to the friction coefficient. The treatment promotes the phase transformation and dislocation movement ...

06-02-2018· 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? It machined...

24-07-2019· 4140 is very nice to machine and the pre-hardened version is a real winner for surface finish. Try 400 fpm for roughing, .020" feed and as big a DOC as you have horsepower for. I was doing .19" DOC in a 3" diameter pre-hardened bar while testing a new Iscar tool (.032 nose rad) and that was about the limit for my 10hp spindle.

In dry grinding, as there is no coolant lubricant to transfer the heat from the contact zone, generation of surface damages are not preventable. Promising alternatives to conventional flood coolant applications are also Minimum Quantity Lubricant (MQL) or Near Dry Machining (NDM) or Semi Dry Machining (SDM). As the name implies, MQL machining uses a very small quantity of lubricant delivered ...
