ASTM A790 Duplex Stainless Steel Pipe S32900 Use Of Paper Industry

Product Discription:

Dual phase SS 329 is the first dual phase steel to be reflected in its higher allowable carbon content. AISI 329 stainless steel is designed for medium temperature strength and excellent corrosion resistance. It can be used for marine applications with hydraulic cylinders or where good corrosion resistance is required. It has excellent corrosion resistance, especially in chloride storage environments. And it has additional resistance to stress corrosion, pore corrosion, and fatigue corrosion. Its characteristics are hardness, plasticity, and strength. When welding, it is necessary to input as little heat as possible. UNS S32900 stainless steel has slightly lower alloy content than UNS S32205. It exhibits brittleness at high temperatures of 300-900 ° C. It can be welded through welding consumables.

The feature of Duplex 32900:

1. One of the most widely used precipitation hardening grades in the enterprise.

2. Although soft and ductile under solution annealing conditions, it can obtain high performance through a single precipitation or aging treatment.

3. Good corrosion resistance, high hardness, toughness and strength.

4. The coefficient of thermal expansion (TEC) at 20 ° C to 815 ° C (68 ° F to 1500 ° F) is 14.4µm/mC (8µin/inF).

5. Compared with grade 2205, the alloy content is slightly lower.

6. Parts must be annealed in solution at around 1020 ° C to 1100 ° C (1870 ° F to 2010 ° F) and then must be quenched in water.

Domain used by S32900:

• Heat exchanger
• Chemical storage tank
• refinery
• Shaft (Marine) pressure vessel parts
• Flanges, fittings and pipes for the oil and gas industry
• Marine technology
• Paper industry
• Compressor parts
• Seawater desalination plant

The components of S32900 are as follows:
