Alloy 1045 TGP
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.
Alloy 4340 HT
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.
Alloy 4140
4140 alloy steel is a medium carbon, chromium-molybdenum, through-hardening alloy steel that has a good hardenability with high strength and toughness as well as good fatigue and impact resistance after heat treating.
Alloy 9310 Aircraft Quality
9310 alloy steel is a low carbon nickel-chromium-molybdenum case-hardening steel, with good strength and toughness properties. It shows high hardenability, high core hardness and high fatigue strength.
