4140 is a 1% chromium - molybdenum medium hardenability general purpose high tensile steel - generally supplied hardened and tempered in the tensile range of 850 - 1000 Mpa (condition T).4140 is now available with improved machinability, which greatly increases feeds and/or speeds, while also extending tool life without adversley affecting mechanical properties.
4140 is an alloy steel that is supplied in either the annealed or prehardened condition. The prehardened condition is heat treated to a medium hardness (HRC 28/32) and is designated as 4140 HT. 4140 annealed is supplied in the soft condition and can be hardened to RC 54. 4140 annealed is designated as 4140 Ann or simply 4140.
I just read the 4140 pre hard thread and now I have a couple questions. Is the pre Hard the same thing as 4140 HT ? I've always thought it was but maybe I'm wrong ? What about HTSR ? is there another process involved with the HTSR or is stress relieving just a side benefit of the heat treat process best hr 4140

L ets keep it simple. 4140 steel can be welded without problems as long as you follow some simple guidelines. This also applies to AISI 4140 and 4340. We will not be discussing the metallurgical properties of 4140 or trying to explain what happens to its microstructure when it cools too rapidly, just remember that the key is to control our cooling rate.

4140 steel is chromium, molybdenum, manganese steel with good toughness, impact resistance and fatigue strength.1045 has slightly increased tensile strength and yield strength numbers than 1045 as a result of a slightly higher carbon content. Also, as a result of higher carbon content, 1045 is not as easy to weld as 4140.
H.R. 4140 (114th) was a bill in the United States Congress. A bill must be passed by both the House and Senate in identical form and then be signed by the President to become law. This bill was introduced in the 114 th Congress, which met from Jan 6, 2015 to Jan 3, 2017. Legislation not enacted by the end of a Congress is cleared from the books.

Heat Treatment. AISI 4140 alloy steel is heated at 845C (1550F) followed by quenching in oil. Before hardening, it can be normalized by heating at 913C (1675F) for a long period of time followed by air cooling.
4140 Hot Rolled Heat Treated Steel Alro stocks 4140 HR HT -a steel in the 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, CrMo best hr 4140
Tig welding 4140best hr 4140 I had a few jobs come in the shop the other day that were made out of 4140. 4140 is a frequent choice for aircraft tooling mainly because it can be heat treated for much higher hardness than plain steel, and because its more dimensionally stable than cold rolled steel.

AISI 4140 steel is a low alloy steel containing chromium, molybdenum, and manganese. It is widely used across numerous industries and is an excellent material choice due to its toughness, high fatigue strength, and abrasion and impact resistance.
Referred to the Committee on Foreign Affairs, and in addition to the Committee on Armed Services, for a period to be subsequently determined by the Speaker, in each case for consideration of such provisions as fall within the jurisdiction of the committee concerned.
We use a lot of 4140 HR annealed at work, as well as 4140 cold rolled, HR HT, and HT TG&P. First off, in the larger shaft sizes, 6" and up, HR is about all you can get. Secondly, when you're talking about machining a shaft all over, even if you could obtain shafting that large cold finished, it'd be a huge waste of money compared to HR
Kromite CD Hardness and Strength Comparison Chart Kromite CD (4140 modified) steel is a superior alternative to carbon steels and cold roll steels, such as 1018 and/or 1045. Increased benefits include higher tensile and yield strength, better resistance to wear, higher degree of toughness for extended service life, and fine grain best hr 4140
