AISI 4140 Chrome Molybdenum High Tensile Steel

AISI 4140 is a chromium molybdenum alloy steel The chromium content provides good hardness penetration and the molybdenum content ensures uniform hardness and high strength AISI 4140 chrome molybdenum steel can be oil hardened to a relatively high level of hardness The desirable properties of the AISI 4140 include superior toughness good

Vanadium Wikipedia

Vanadium is a chemical element with the symbol V and atomic number 23 It is a hard silvery grey malleable transition metal The elemental metal is rarely found in nature but once isolated artificially the formation of an oxide layer passivation somewhat stabilizes the free metal against further oxidation Andrés Manuel del Río discovered compounds of vanadium in 1801 in Mexico by
