George Metals, a Houston, USA-based company, is a trusted producer and provider of **Stainless Steel 446 Hollow Bars**, providing top-notch solutions for industries that run under extreme temperature and corrosive conditions. Stainless Steel 446 is a heat-resistant ferritic alloy with excellent resistance to oxidation, scaling, and thermal fatigue. George Metals produces hollow bars with accuracy and consistency and provides outstanding machinability and structural integrity. These empty bars are most suitable for uses that demand inner passageways, lower weight, and thermal resistance, so they are most useful in industries such as furnace making, petrochemicals, power generation, and high-temperature gas handling systems.
**Stainless Steel 446 Empty Bars** have 23–27% chromium content, extremely low carbon (≤0.20%), and traces of molybdenum, silicon, manganese, and sulfur. The high chromium content provides the alloy with outstanding corrosion and oxidation resistance, particularly at elevated temperatures. Its mechanical properties are tensile strength of 485–620 MPa, yield strength of approximately 275 MPa, and elongation of 20–25%. The product, **Stainless Steel 446 Hollow Bar**, is heat-treatment non-hardenable but has satisfactory dimensional stability, thermal conductivity, and resistance to carburizing and sulfidizing atmospheres—suitable for applications at high heats with corrosive exposure.
