Duplex Steel S32205 / S31803 Pipe Fittings

These fittings are nitrogen enhanced duplex pipe fittings to oppose normal corrosion issues. This grade is completely austenitic and little ferrite. It is the most common grade from the family of stainless steel. One of the best benefits of duplex pipe fittings is that it consolidates the great properties of ferritic grade. The use of duplex pipe fittings should be limited below 600 deg F. However above this temperature range it turns in to embrittled.

These Duplex S32205/S31803 Pipe Fittings pipe fittings are a great solution for many applications where other stainless steel pipe fittings are helpless to chloride stress corrosion cracking. When pipe fittings are subjected to tensile stress while exposed in solution chlorides the stress corrosion cracking is encountered. Elevating temperatures create a weakness to stress corrosion cracking. The composition of nitrogen, chromium and molybdenum display very good resistance to crevice and pit corrosion. These pipe fittings are ideal for use in marine applications, brackish water, and chemical processing industries. Duplex pipe fittings are coated to prevent contamination when exposed to mild environments. Moreover, the chemical chemistry of these pipe fittings offers great corrosion resistance.

Characteristics of Duplex S32205/S31803 Pipe Fittings:
• Excellent resistance to chloride stress corrosion cracking
• Highly resistive to crevice and pitting corrosion
• Local and general corrosion resistance
• Sufficient sulfide stress corrosion resistance
• Elevated strength
• Prominent workability and weldability

Packaging of Duplex S32205/S31803 Pipe Fittings is done in wooden cases, wooden pallets, cases and woven bags. This pipe fittings packing is rolled with a thin film of plastic to prevent contamination while exporting the products.
