2507 Duplex Stainless Steel Strip
Type 2507 is a super-duplex (austenitic/ferritic) stainless steel designed for applications that require exceptional strength and corrosion resistance surpassing that of 304 and 316 stainless steels.
2507 Duplex Stainless Steel Strip has excellent resistance to stress corrosion cracking as well as pitting, crevice, and erosion corrosion. Alloy 2507 also has high thermal conductivity, a low coefficient of thermal expansion, and good weldability.
The material is supplied in a solution-annealed state, with a thickness ranging from 0.015 mm to 3.5 mm and a maximum width of 300 mm. It is available in 2B, BA, and surface treatments to meet various processing requirements such as stamping, deep drawing, and welding.

Processing available
Slitting/Cutting, Leveling/Length Cutting
Cold-rolled strip surface treatment: 2B, BA, No.1, and other surface finishes
Welding consumables: ER2594 (welding wire) or E2594 (welding electrode) are recommended for welding, and interpass temperature control is necessary.
Advanced manufacturing processes
01
Edge crack control
Utilizing an optimized hot rolling process, edge crack depth is controlled to within 5mm, resulting in a high yield.
02
σ phase suppression
Precise solution annealing followed by water quenching effectively suppresses σ-phase precipitation and ensures equilibrium of the biphase microstructure.
03
Purity control
Ultra-low inclusion control ensures corrosion resistance, making it suitable for harsh working conditions, such as those found in seawater and chemical industries.
04
Supporting services
We provide slitting, leveling, and length processing services, as well as the selection of matching welding materials.
