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).
In addition to the descriptive steel grade naming system indicated above, within EN 10027-2 is defined a system for creating unique steel grade numbers. While less descriptive and intuitive than the grand names they are easier to tabulate and use in data processing applications. The number is in the following format: x.yyzz(zz)

4140 [definition needed] 6150, a chromium-vanadium alloy. Similar to 4140, 6150 is a tough steel with high impact resistance. It can be hardened to the mid-50s on the HRC scale. [citation needed] While a common material for swords or hatchets, it is less than ideal for most knives because of its limited attainable hardness.
The Y(4140) particle is an electrically neutral exotic hadron candidate that is about 4.4 times heavier than the proton. It was observed at Fermilab and announced on 17 March 2009. [ 1 ] This particle is extremely rare and was detected in only 20 of billions of collisions.
