Duplex Stainless Steel Pipe

ASTM A790 duplex stainless steel pipe is manufactured in accordance with the American standard for seamless and welded ferritic-austenitic duplex stainless steel pipe. This specification covers pipe intended for general corrosive service, with particular emphasis on applications requiring high strength and excellent resistance to pitting, crevice corrosion, and stress corrosion cracking. Our ASTM A790 duplex pipes are available in standard duplex grades (2205), super duplex

2507 super duplex stainless steel pipe is a high-performance duplex grade with a two-phase microstructure consisting of approximately 50% austenite and 50% ferrite. It belongs to the super duplex family and offers exceptional strength combined with outstanding corrosion resistance. With a Pitting Resistance Equivalent Number (PREN) exceeding 41, 2507 provides superior resistance to pitting, crevice corrosion, and stress corrosion cracking in the harshest environments,

2207 Stainless Steel Plate， Super Duplex Grade for Extreme Environments

Duplex stainless steel sheet is a family of stainless steel grades with a mixed austenitic-ferritic microstructure (approximately 50% austenite / 50% ferrite). This unique structure delivers approximately twice the yield strength of standard austenitic grades like 304 or 316, combined with excellent resistance to chloride stress corrosion cracking (SCC), pitting, and crevice corrosion. Duplex stainless steel sheets are the material of choice for demanding applications in

Duplex 2507 Pipe Super Duplex Stainless Steel for Extreme Corrosive Environments

S32750 Super Duplex Tube ASTM A790

2205 duplex stainless steel pipe is a nitrogen-enhanced duplex grade with a two-phase microstructure consisting of approximately 50% austenite and 50% ferrite. This balanced structure provides approximately twice the yield strength of standard austenitic stainless steels such as 304 and 316, combined with excellent corrosion resistance. 2205 is the most widely used duplex stainless steel grade, offering an exceptional combination of high strength, good weldability, and

Duplex stainless steel pipe is manufactured from a family of stainless steels with a two-phase microstructure consisting of approximately equal parts of austenite and ferrite. This unique structure provides a combination of high strength and excellent corrosion resistance that exceeds standard austenitic grades like 304 and 316.Our duplex stainless steel pipes offer superior resistance to stress corrosion cracking, pitting, and crevice corrosion, making them ideal for

UNS S32101 is a lean duplex stainless steel grade that offers a balanced combination of good strength, excellent corrosion resistance, and cost-effectiveness. It belongs to the lean duplex family (also known as LDX 2101®), containing lower nickel and molybdenum than standard duplex grades like 2205, making it a more economical alternative without significantly compromising performance. Manufactured in accordance with ASTM A789 and ASTM A790, UNS S32101 tubes are available in

ASTM A789 UNS S32750 super duplex stainless steel tube is a premium-grade product designed for the most demanding industrial applications. With a higher chromium, molybdenum, and nitrogen content than standard duplex grades (e.g., 2205/S31803), UNS S32750 offers superior strength and exceptional corrosion resistance, particularly in aggressive chloride-containing environments. This tube is manufactured in accordance with ASTM A789, covering both seamless and welded ferritic

UNS S31803 duplex stainless steel pipe is a widely used duplex grade that offers a balanced mix of good strength, excellent corrosion resistance, and cost-effectiveness. It is the original standard duplex stainless steel, commonly specified in ASTM A790 and ASTM A789 for both seamless and welded pipe applications.With a dual-phase microstructure (austenite + ferrite), UNS S31803 provides approximately twice the yield strength of 304 or 316L austenitic stainless steels, while

2205 duplex stainless steel pipe offers a balanced combination of high strength and excellent corrosion resistance, making it the preferred choice for industries such as oil & gas, chemical processing, marine engineering, and desalination plants. With a duplex microstructure (approximately 50% austenite + 50% ferrite), 2205 provides nearly twice the yield strength of common austenitic stainless steels like 304 or 316L, while maintaining good weldability and fabricability.
