1. 4340 Steel Introduction
AISI 4340 steel is a medium carbon, low alloy steel known for its toughness and
strength in relatively large sections. AISI 4340 is also one kind
of nickel chromium molybdenum steels. 4340 alloy steel is generally
supplied hardened and tempered in the tensile range of 930 - 1080
Mpa. Pre hardened and tempered 4340 steels can be further surface
hardened by flame or induction hardening and by nitriding. The 4340
steel has good shock and impact resistance as well as wear and
abrasion resistance in the hardened condition. AISI 4340 steel
properties offer good ductility in the annealed condition, allowing
it to be bent or formed. Fusion and resistance welding is also
possible with our 4340 alloy steel. AISI 4340 material is often
utilized where other alloy steels do not have the hardenability to
give the strength required. For highly stressed parts it is
excellent choice. AISI 4340 alloy steel can also be machined by all
customary methods.
