stainless steel pipe

UNS S32304 is a duplex stainless steel that contains a combination of austenitic and ferritic phases. It has a high resistance to corrosion, especially in chloride environments, making it suitable for use in chemical processing, oil and gas, and offshore industries. The duplex structure also provides high strength and toughness, making it ideal for applications that require both corrosion resistance and mechanical properties. UNS S32304 Duplex Stainless Steel Tube is a seamless or welded tube made from this material and is commonly used in heat exchangers, boilers, and pressure vessels.

Duplex S32304 is a two-phase, ferritic, austenitic 23% chromium, 4% nickel, molybdenum-free duplex stainless steel. It has similar corrosion resistance properties to 316L. Furthemore, its mechanical properties are twice those of 304L/316L austenitic grades. This allows the designer to save weight, particularly for properly designed pressure vessel applications. It is partcularly suitable for applications covering the -50 °C/+300 °C temperature range.

Stainless Seamless Pipe Quality Control:

1.Raw materials pipe blank quality classification: high quality, medium, economical

2.Raw materials inspection after receive in factory

3.After pickled, tube will be grinded careful to less defect

4.Multiple cold drawn/rolled process for precision dimension

5.Standard heat-treated of continuous annealed/solution for better property, intergranular corrosion

6.Full Inspection: ET, UT, Hydraulic Test, Penetration Test, Grinded, Sand Blast, Print Making
