Anucha Metals, based in Bangkok, Thailand, stands out as a top manufacturer and supplier of high-quality stainless steel products, including Stainless Steel 303 Hex Bars and Rods. Known for their precision engineering and commitment to customer service, Anucha Metals crafts stainless steel solutions specifically designed for machining-heavy and industrial uses. Their 303 hex bars and rods are produced with cutting-edge technology and rigorous quality standards, ensuring an exceptional surface finish, precise dimensions, and reliable mechanical performance. Catering to sectors like automotive, electronics, and machinery manufacturing, Anucha Metals supplies dependable, corrosion-resistant stainless steel materials for challenging operating conditions across Thailand and beyond.
Stainless Steel 303 Hex Bars and Rods are mainly made up of 17–19% Chromium and 8–10% Nickel, with a touch of Sulfur to enhance machinability. You’ll also find small amounts of Manganese, Silicon, Phosphorus, and Carbon in the mix. The addition of Sulfur boosts the free-machining properties, making 303 the go-to choice for easily machinable austenitic stainless steel. It boasts a tensile strength of about 500–750 MPa, a yield strength of around 190 MPa, and impressive elongation characteristics. While its corrosion resistance isn’t quite as high as that of 304, its remarkable workability and surface finish make it perfect for crafting precision components.
