AISI E3310 is a chromium-nickel carburizing steel having exceptionally high hardenability. It is suited for heavy duty parts which must have high surface hardness combined with a strong and tough core. This datasheet provides information on composition, physical properties, hardness, and tensile properties as well as fracture toughness. It also includes information on forming, heat treating, machining, and joining. Filing Code: SA-35. Producer or source: Alloy steel mills and foundries.
