Overview
CA15 is a "400 series" material that is a hardenable stainless alloy with enough chromium present to make it resistant to rusting and mildly corrosive environments. A wide range of hardness is obtainable through various tempering treatments. It’s readily machinable and weldable but should be annealed or stress relieved since this alloy is air-hardenable. This metal alloy is also known as MTEK 410.
Typical Uses
Bearings, bushings, chemical and food processing equipment, conveyor rollers, cutlery, impellers, medical devices, pump and valve components, turbine engine parts, shaft sleeves, liners, and aircraft parts.
