Stainless steel is one of the most wide spread alloys used in practically every industry. It contains mostly iron and no less than 10.5% of chromium which makes this material corrosion resistant. Thanks to it's prominent properties, stainless steel is used everywhere, from cooking utensils to giant constructions. It is used as the material for metal 3D printing as well.

Stainless steel alloy usually contains iron, chromium, manganese, silicon, carbon, and sometimes nickel and molybdenum. This material is used in almost every industry and technologies (like CNC machining and milling) as it's both strong and has good corrosion resistance. However, after sustained contact with water, it can eventually corrode. Stainless steel has lots of different types (grades) that each have various properties depending on the additives they contain, though minimum 10.5% of chromium is a must. The main grades of stainless steel are:
316L is one of the most popular stainless steel grades used in 3D printing. This material has better mechanical properties thanks to the high temperature gradient and fast rate of solidification.
