2507 is a duplex stainless steel with a microstructure consisting of austenite and ferrite in nearly equal proportions. Its chemical composition and microstructure give it good strength, corrosion resistance and toughness, and its annealed yield strength is twice that of typical austenitic stainless steels, with comparable impact strength. 2507 exhibits good corrosion resistance in many acidic environments and has excellent resistance to chloride stress corrosion cracking, pitting, and crevice corrosion.

2507 duplex stainless steel exhibits superior performance through its rich chemical composition. Its duplex construction gives it a good balance in terms of strength and corrosion resistance. The material is widely used in the chemical, marine, energy and other fields that require high strength and corrosion resistance. Not only does 2507 perform well in generally corrosive environments, but it also maintains excellent stability in challenging chloride environments, ensuring reliable engineering materials under harsh conditions.
