ASME SA789 Super Duplex 2507 UNS S32750 Seamless Duplex Tube For Heat Exchanger
ASTM A789/ ASME SA789 Super Duplex 2507, also known as S32750, is a
type of stainless steel that exhibits a unique combination of
austenitic and ferritic properties (consist of approximately 50%
austenite and 50% ferrite). This composition provides excellent
mechanical strength and corrosion resistance.
The comparative advantages including: Higher Chromium and
Molybdenum Content: 1. Compared to standard austenitic stainless
steels, S32750 offers superior corrosion resistance, especially
against chlorides and reducing environments. 2. Resistance to
Localized Corrosion: Its resistance to pitting and crevice
corrosion is significantly higher than that of conventional
stainless steels.
