Your choice of a method when micromachining stainless steel will be determined by the following five categories:
- Ferritic steels are chromium-based alloys with less than 0.10% carbon.
- Austenitic steels contain a blend of nitrogen, nickel, and manganese for added toughness, besides a mix of chromium and molybdenum for corrosion resistance.
- Duplex steels have properties that are partly (50%) austenitic and partly (50%) ferritic, giving them a higher tensile strength than the two varieties.
- Martensitic steels have ferritic properties, with increased carbon levels of up to 1% for extra strength.
- Precipitation hardened steels are combined with other metals like copper and aluminum, making them the toughest variety.
