303 free-cutting steel bars

303 stainless steel is a chromium-nickel stainless steel known for its excellent corrosion resistance and outstanding machinability. Its main components include 18% to 20% chromium, 8% to 10% nickel, and 0.15% to 0.35% sulfur, which allow it to perform well in mildly corrosive environments, making it suitable for various industrial applications.

In the machining field, 303 stainless steel is commonly used for manufacturing precision components such as screws and nuts. Its higher sulfur content enhances cutting performance, improving production efficiency. With a tensile strength typically ranging from 500 to 700 MPa, it can withstand significant loads.

303 stainless steel is also widely used in the food processing industry due to its corrosion resistance and hygienic properties. Additionally, it has important applications in the aerospace sector. Its excellent performance makes it an indispensable material across multiple industries.
