2507 Super Duplex Stainless Steel Elbow

Grade: 2507/S32750 /S32760

Elbow types:

90° Long Radius, 90° Short Radius, 45° Elbow, 180° Return, 3D / 5D Elbow

Standards:

ASME B16.9, EN 10253-4:2025, JIS B2312/2313 etc.

2507 is a super duplex stainless steel designed for highly demanding corrosive services. Its high chromium, molybdenum and nitrogen contents provide excellent resistance to pitting, crevice corrosion and chloride stress-corrosion cracking, while the duplex structure provides high mechanical strength. 2507 fittings are widely specified for seawater, offshore oil and gas, desalination and aggressive chemical-process piping.
