Material

Stainless Steel (C465)

Stainless Steel C465 is an age-hardenable chromium-nickel based steel alloy that offers excellent strength, fracture toughness, and corrosion resistance. This material is an ideal choice for the aerospace, maritime, and medical industries, as well as other industrial applications where high strength and hardness are required, such as injection molds, drilling machines, and other tools.

Actual values may vary with build conditions.

Strong tensions due to part geometry may distort parts, potentially leading to greater deviation in values. Values for surface roughness depend on the orientation of the surface; downward-facing surfaces and surfaces with support will be rougher.

These values show the material characteristics with additional stress relief heat treatment. Extra heat treatment steps, cryogenic treatment, or aging for even higher mechanical properties may be possible, e.g. for serial-produced parts.
