Chuck Metals is a well-known manufacturer of many high quality SS 446 Hollow Bars. These hollow rods are highly demanded in the engineering industry due to their unique properties. SS 446 is a high chromium ferritic grade, known for its excellent resistance to heat and corrosion in harsh environments. Available in a variety of sizes, shapes, lengths and thicknesses, we also offer customized SS 446 Hollow Bars to meet the specific needs of our esteemed customers. With excellent tensile strength and durability at elevated temperatures, SS 446 hollow bars are ideal for complex industrial applications.
SS 446 Hollow Bar is composed primarily of iron, with high chromium content (22-26%) and small amounts of nickel, manganese, and silicon. This composition provides excellent resistance to oxidation, corrosion, and high-temperature environments. The mechanical properties of SS 446 include a tensile strength of 500-700 MPa and a yield strength of 220-380 MPa. It has a high hardness range of 200-250 HB and maintains its strength even at elevated temperatures. This makes SS 446 Hollow Bar ideal for applications requiring durability, strength, and resistance in extreme conditions.
