Stainless steels are iron alloys with a minimum of ~10.5% chromium, which forms a protective oxide film for corrosion resistance. They are categorized by their metallurgical microstructure into five main families: austenitic, ferritic, martensitic, duplex, and precipitation-hardened (PH) stainless steels. Each family has distinct compositions, properties, and applications. Below is a comprehensive overview of these categories, including key characteristics and popular grades (such as 304, 316, 430, 410, 2205, and 17-4PH), with their standard designations, chemical compositions, mechanical properties, and typical uses.

The Importance of Material Selection in CNC Machining
Selecting the right material is as crucial as any design or engineering decision. Materials are not just the substance of the final product but a cornerstone upon which the success of the machining process rests. From predominant metals such as aluminum, brass, copper, and steel to exotic materials like Inconel and Monel, along with versatile plastics and composites, each material brings its unique properties and challenges to the table. In this introduction to materials, you’ll discover a vast world where entire disciplines, like Material Science, are dedicated to exploring the significance of material selection in CNC machining and how it affects the final product’s quality, functionality, and suitability for its intended application.
