303 Stainless Steel: Contains approximately 18% chromium and 8% nickel. Additional elements like sulfur and selenium are included to enhance machinability.
304 Stainless Steel: Comprises around 18% chromium and 8% nickel, with common additions of carbon, manganese, and silicon.
316 Stainless Steel: Features about 16% chromium, 10% nickel, and 2% molybdenum. It has slightly higher nickel and molybdenum for improved corrosion resistance compared to 304.
1018 Steel: Main components include iron, carbon (0.15-0.20%), manganese (0.60-0.90%), and trace elements. Its low carbon content contributes to favorable machinability.
1045 Steel: Consists of iron, carbon (0.43-0.50%), manganese (0.60-0.90%), and other minor elements. Classified as a medium-carbon steel, it provides increased strength and hardness.
These compositions serve as a general guide, and precise specifications may vary depending on the manufacturer and industry standards. For detailed information on the composition of a specific steel alloy used in CNC machining, referring to material data sheets or industry standards is crucial.
