AISI 4340 alloy steel is a medium carbon nickel-chromium molybdenum alloy steel that creates an excellent combination of ductility, toughness, and strength after heat treating. It has good shock and impact resistance as well as wear and abrasion resistance in the hardened condition.
NOTE 5. Where minimum and maximum sulphur content is shown it is indicative of resulphurized steel. NOTE 6. The chemical ranges and limits shown above are produced to check analysis tolerances shown in the AISI manual. NOTE 7. Standard alloy steels can be produced with a lead range of 0.15/0.35 percent.
AISI 1045 is a medium carbon steel containing approximately 0.45% carbon that can be hardened by heat treatment to a maximum surface hardness of approximately Rockwell C 54-60 after flame or induction hardening.
About 4130 (E4130) Alloy Steel. Aircraft quality 4130 alloy steel is a medium carbon, low alloy steel containing 0.15/0.25% molybdenum and 0.80/1.10% chromium as strengthening agents. This type of steel is also commonly referred to as a chromoly steel, or chrome moly steel. Due to its relatively low carbon content of 0.28/0.33%.
