If you need premium alloy steel, we have you covered. Discover our 4140 steel stock below.
The versatile 4140 is a chromium-molybdenum grade steel used in a multitude of industries and applications due to its good ductility and shock resistance. Greater carbon content gives it higher strength and better hardenability than 4130, although it is more difficult to weld.
