Stainless Steel 416 Flat Bars are a martensitic stainless steel grade that has been enhanced with sulfur to boost machinability. Typically, their composition features 12–14% chromium, 0.15% carbon, 0.15% sulfur, along with trace amounts of manganese and silicon. These flat bars offer moderate corrosion resistance while facilitating efficient machining and fabrication. In terms of mechanical properties, they showcase a tensile strength of 700–850 MPa, a yield strength of around 450–500 MPa, and a hardness that ranges from 200–300 HB. With heat treatment, their hardness and wear resistance can be further improved, making Stainless Steel 416 Flat Bars perfect for components that demand toughness, durability, and precision machining.
