4340 Forged Bar Characteristics

AISI 4340 steel is one kind of nickel chromium molybdenum, low alloy steel known for its toughness and strength in relatively large sections.  4340 alloy steel is generally supplied hardened and tempered in the tensile range of 135KSI – 160KSI. Pre hardened and tempered AISI 4340 steel can be surface hardened by flame or induction hardening and by nitriding. AISI 4340 steel has good shock and impact resistance as well as wear and abrasion resistance in the hardened condition.   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. Our AISI 4340 alloy steel bars can also be machined by all customary methods.
