Einsatzbeispiele

For use in applications where welding is necessary, subsequent annealing and quenching is impracticable, and exposure to most severely corrosive media is involved.
These products have been used typically for parts requiring good corrosion resistance and which will be subjected to elevated temperatures during fabrication or in service and for parts requiring oxidation resistance up to 816°C (1500°F), but usage is not limited to such applications.
This tubing has been used typically for parts requiring both corrosion and heat resistance, especially when subjected to welding, brazing, or other exposure to temperatures over 427°C (800°F) during fabrication, and also for parts requiring oxidation resistance up to 816°C (1500°F) but useful at that temperature only when stresses are low. Usage is not limited to such applications.
This tubing has been used typically in high-pressure hydraulic or pneumatic systems assembled with brazed joints, but usage is not limited to such applications.
This wire has been used typically for screening and stitching applications requiring good corrosion resistance and has satisfactory oxidation resistance up to 816 °C (1500 °F) but is useful at that temperature only when stresses are low.
