2507 stainless steel strip is a super duplex stainless steel strip composed of 25% chromium, 4% molybdenum and 7% nickel alloy.
Super duplex 2507 stainless steel strip is a ferritic-austenitic stainless steel strip, which combines the most beneficial properties of many ferritic stainless steel strip(430 stainless steel strip) and austenitic stainless steel strip(such as 304L stainless steel strip, 310S stainless steel strip, 321 stainless steel strip, 347 stainless steel strip).
Because the 2507 stainless steel strip contains high contents of chromium and molybdenum, so it has extremely good resistance to pitting, crevice corrosion and uniform corrosion.
The dual-phase microstructure ensures that the 2507 stainless steel strip has a high resistance to stress corrosion cracking, and the mechanical strength of it is also high.
