Duplex Stainless Steel - SS 329 / S32900 / 1.4460 Maching Performance
SS 329 Stainless steels are high-alloy steels which have high corrosion resistance than other steels owing to the presence of large amounts of chromium in the range of 4 to 30%. Duplex Stainless steel 329 can be used for heat exchangers, chemical tanks, refineries, shafts (marine, etc) pressure vessel parts, flanges, fittings & pipes for the oil and gas industries and offshore technology, paper industry, compressor parts.

Principal Design Features of Duplex Stainless Steel - SS 329
One of the most widely used precipitation hardening grades in the business. While soft and ductile in the solution annealed condition, S32900 is capable of high properties with a single precipitation or aging treatment. Characterized by good corrosion resistance, high harness, toughness and strength.
SS 329 Machinability
Long, gummy chips characterize this alloys machinability. It can be machined in the annealed condition, however condition
S32900 Welding
Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding.
1.4460 Forging
Soak for 1 hour at 2150 F (1177 C) prior to forging. Do not work below 1850 F (1010 C). Post-work solution treatment is required prior to final hardening.
