AISI Alloy 4340 Steel Supply  Good Toughness AISI Alloy 4340 Steel Supply 

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. ASTM 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.songshunmoldsteel41404340
