General Corrosion
For hot working 2507, maintain temperatures between 1875°F and 2250°F, followed by a solution anneal at a minimum of 1925°F and rapid air or water quenching for optimal results.
Cold working 2507 is compatible with most standard stainless steel forming processes. However, due to its higher yield strength and lower ductility compared to austenitic steels, fabricators may require more force, larger bending radii, and greater allowance for springback. Techniques like deep drawing and stretch forming are more challenging but achievable with proper planning. For cold deformation exceeding 10%, a solution anneal and quench is recommended.
2507 stainless steel should undergo solution annealing and quenching after both hot and cold forming. Perform solution annealing at temperatures of at least 1925°F, followed by a rapid air or water quench. Post-heat treatment, pickle and rinse the products to achieve optimal corrosion resistance.
Our 2507 stainless steel exhibits excellent weldability, allowing it to be joined to itself or other materials using various methods including shielded metal arc welding (SMAW), gas tungsten arc welding (GTAW), plasma arc welding (PAW), flux cored wire (FCW), or submerged arc welding (SAW). For the best duplex weld structure, use 2507/P100 filler metal when welding.
2507 is not required, except to prevent condensation on cold metal. The Interpass
Our stainless steel sheets are available in a range of exquisite finishes, including brushed, 2B smooth, and 8K mirror finishes, catering to diverse aesthetic and functional needs.
Each stainless steel sheet's finished side is protected with an easily removable film, safeguarding the material from wear and marks during fabrication or installation. The backside remains unfinished.
2205 Grade Stainless Steel Sheet is a popular choice due to its ease of welding and forming, coupled with excellent corrosion resistance.
