What is 2507 stainless steel

What is 2507 stainless steel

Alloy 2507 is a super duplex stainless steel containing 25% chromium, 4% molybdenum and 7% nickel, designed for demanding applications that require exceptional strength and corrosion resistance, such as chemical processing, petrochemical and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and low coefficient of thermal expansion. High chromium, molybdenum and nitrogen content provides excellent resistance to pitting, crevasses and overall corrosion.

The impact strength is also very high. Alloy 2507 is not recommended for use in applications requiring prolonged exposure to temperatures above 570°F due to the risk of reduced toughness.

Mechanical property
Mechanical and physical properties

The 2507 combines high tensile and impact strength with a low coefficient of thermal expansion and high thermal conductivity. These characteristics apply to many structural and mechanical components. The low temperature, ambient temperature and high temperature mechanical properties of 2507 sheet are shown below. All test data shown are for samples in the annealed and quenched state.

2507 is not recommended for applications that require prolonged exposure to temperatures exceeding 570°F due to the increased risk of reduced toughness. The data listed here are typical for forged products and should not be considered as maximum or minimum values unless specifically stated.
