Duplex 2507 (UNS S32750) is a super duplex stainless steel with 25%
chromium, 4% molybdenum, and 7% nickel designed for demanding
applications which require exceptional strength and corrosion
resistance, such as chemical process, petrochemical, and seawater
equipment. The steel has excellent resistance to chloride stress
corrosion cracking, high thermal conductivity, and a low
coefficient of thermal expansion. The high chromium, molybdenum,
and nickel levels provide excellent resistance to pitting, crevice,
and general corrosion.

2. Corrosion
General Corrosion
1). high chromium and molybdenum content of 2507 makes it
extremely resistant to uniform corrosion by organic acids like
formic and acetic acid.
2). provides excellent resistance to inorganic acids,
especially those containing chlorides.
3). can be used in dilute hydrochloric acid.
4). Pitting need not be a risk in the zone below the
borderline in this figure, but crevices must be avoided.
Intergranural Corrosion
1). Low carbon content greatly lowers the risk of carbide
precipitation at the grain boundaries during heat treatment.
2). Is highly resistant to carbide-related intergranular
corrosion.
Stress Corrosion Cracking
1). Duplex structure of 2507 provides excellent resistance to
chloride stress corrosion cracking (SCC).
2). Superior to 2205 in corrosion resistance and strength.
3). 2507 is especially useful in offshore oil and gas
applications and in wells with either naturally high brine levels
or where brine has been injected to enhance recovery.
Pitting Corrosion
1). Different testing methods can be used to establish the
pitting resistance of steels in chloride-containing solutions.
Crevice Corrosion
1). Highly resistant to crevice corrosion.
