2507 is a duplex stainless steel with a microstructure consisting of austenite and ferrite phases in approximately equal amounts. The chemical composition and microstructure impart a good combination of strength, corrosion resistance and toughness with an annealed yield strength twice that of typical austenitic stainless steels possessing comparable impact strength. 2507 exhibits good resistance to general corrosion in many acid environments with exceptional resistance to chloride stress corrosion cracking, pitting and crevice corrosion.
