SS 446 Flanges
The grade 446 stainless steel alloy, a high chromium ferritic stainless steel renowned for its increased temperature strength and corrosion resistance, is used to make the components that make up stainless steel 446 flanges. These flanges are appropriate for uses where resistance to extreme heat and particular corrosive conditions is needed.
Stainless Steel 446 offers excellent high-temperature strength and oxidation resistance at elevated temperatures up to 1100°C (2012°F). It maintains its mechanical properties even in prolonged high-temperature exposure.
Stainless Steel 446 flanges offer excellent high-temperature strength and oxidation resistance, making them suitable for applications in industries where exposure to extreme heat and specific corrosive conditions is common. Their stability at elevated temperatures makes them valuable in environments where other stainless steel grades might not perform as effectively. Proper selection and installation following industry standards are essential for ensuring the optimal performance of these flanges in high-temperature applications.
