UNS S32750 Super Duplex 2507 Stainless Steel
Introduction
Overview of UNS S32750 Super Duplex 2507 Stainless Steel
UNS S32750 super duplex stainless steel, also known as 2507 duplex stainless steel.
UNS S32750 is the standard grade of super-duplex stainless steel based on 25% chromium, 7% nickel and significant additions of molybdenum, manganese and nitrogen.
As with many of the duplex grades, UNS S32750 also offers high strength and excellent resistance to chloride stress corrosion cracking, while the molybdenum and nitrogen levels enhance the pitting, crevice and general corrosion resistance.
It is widely used in oil and gas, hydropower, pressure vessels, pulp and paper, structural components and chemical tankers.

The History Of Duplex 2205 And 2507 Stainless Steel
Duplex 2205 and 2507 stainless steel is an alloy which combines many of the most beneficial properties of ferritic steel and austenitic steel. Due to the high content of chromium and molybdenum, the steel has excellent resistance to pitting corrosion, crevice corrosion and uniform corrosion.
What’s The Difference Between 2205 And 2507 Stainless Steel Strip?
2205 and 2507 stainless steel strips are stainless steels containing molybdenum. The molybdenum content in 2507 stainless steel strip is slightly higher than 2205 stainless steel strip. Due to the molybdenum and high chromium contents in the stainless steel, the overall performance of 2205 and 2507 stainless steel strip is better than 317L stainless steel strip.
