SAE AISI 4140 Steel vs. SAE AISI 4340 Steel :MakeItFrom

Both SAE AISI 4140 steel and SAE AISI 4340 steel are iron alloys. They have a very high 98% of their average alloy composition in common. For each property being compared, the top bar is SAE AISI 4140 steel and the bottom bar is SAE AISI 4340 steel.

4140 vs. Stainless Steel The High Road

Feb 10, 2011 · The heat treated numbers for 4140 are correct, but barrels have to be pretty soft to gun drill them and rifle. Maybe if they were heat treated afterwards we would see something. But then the barrels would probably warp. You can check out material properties on MatWeb. Metals really improve with heat treatment. But only actions are heat treated.

AISI 4140 Alloy Steel (UNS G41400)

Alloy steels are designated by AISI four digit numbers and comprise different kinds of steels, each with a composition which exceeds the limitations of B, C, Mn, Mo, Ni, Si, Cr, and Va set for carbon steels. AISI 4140 alloy steel is a chromium , molybdenum , and manganese containing low alloy steel

4150 Carbon Steel vs 416 R Stainless – Which is Right for

Faxon is often asked which barrel material we’d recommend for a given application. Typically, the answer to the question all depends on what you, as the shooter, are going for in your intended build and its application.Faxon only uses 4150 or 416 R steels in its barrels; the highest grade of each series of steels, carbon and stainless, respectively.

41xx steel Wikipedia

41xx steel is a family of SAE steel grades, as specified by the Society of Automotive Engineers (SAE). Alloying elements include chromium and molybdenum, and as a result these materials are often informally referred to as chromoly steel (common variant stylings include chrome moly, cro moly, CrMo, CRMO, CR MOLY, and similar).

How To Weld 4140 Steel WELDING ANSWERS

When joining to metals with lower tensile strength (like 4140 and A36) you only need to match the strength of the weaker base metal. So welding A36 to 4140 can be done with a E7018. For 4145 to 4140 you can use E12018, but keep in mind 4140 may have a tensile strength as low 94 Ksi, in which case E10018 would suffice.

Using 316 in place of 4140? WeldingWeb

Oct 22, 2009 · I am trying to make a gun bolt off of a set of blueprints for a rifle, and the blueprints call for the use of 4140 steel. My question is what would be the advantage to using 4140 over say 316 stainless? From the Rockwell charts and properties I have found on both materials, the 316 seems to be harder, and stronger. Then again I could be reading them wrong.
