They pride themselves on precision, durability, and ensuring customer satisfaction, delivering products that align with international standards. By blending cutting-edge manufacturing techniques with strict quality control, Semih Metals guarantees consistent performance and reliability. Catering to a wide array of industries, they have built a solid reputation for excellence, providing customized solutions tailored to meet the unique needs of their clients. Their Stainless Steel 304L Square Bars and Rods are perfect for applications that require both corrosion resistance and structural integrity.
These Stainless Steel 304L Square Bars and Rods are primarily made up of iron, with 18–20% chromium and 8–10% nickel, featuring a low carbon content of less than 0.03% to improve weldability. This type of austenitic stainless steel showcases remarkable corrosion resistance, especially in acidic and chlorinated environments. On the mechanical side, 304L bars and rods boast a tensile strength of about 485 MPa and a yield strength of around 170 MPa, along with impressive elongation properties close to 40%. Their low carbon content helps minimize carbide precipitation during welding, which prevents intergranular corrosion while maintaining high toughness and formability for various engineering applications.
