1. Products Details
WUXI XINFUTIAN METAL PRODUCTS CO., LTD inventory now includes
Duplex 2507, which is a super duplex stainless steel with 25%
chromium, 4% molybdenum, and 7% nickel. This alloy is designed for
applications which require exceptional strength and corrosion
resistance; examples include applications in chemical processing,
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
