二重ステンレス鋼の管

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 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

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

Seamless duplex stainless steel tube is manufactured without any weld seam, produced by extruding a solid billet of duplex stainless steel into a hollow tube through a piercing and rolling process. The absence of a weld seam provides superior strength, uniform wall thickness, and excellent performance under high pressure, high temperature, and corrosive conditions. Our seamless duplex tubes offer the unique combination of high strength (approximately twice that of austenitic

Corrosion resistant duplex steel pipe is specifically engineered for service in aggressive environments where standard stainless steels such as 304 and 316 are prone to failure. The unique two-phase microstructure (austenite + ferrite) combined with elevated levels of chromium, molybdenum, and nitrogen provides exceptional resistance to a wide range of corrosive attack mechanisms. Our duplex steel pipes offer outstanding protection against pitting, crevice corrosion, stress

Oil and gas duplex stainless steel tubing is specifically engineered for the demanding environments encountered in upstream, midstream, and downstream operations. The unique two-phase microstructure (austenite + ferrite) combined with high chromium, molybdenum, and nitrogen content provides exceptional resistance to the corrosive conditions typical of oil and gas production, including sour service (H₂S), carbon dioxide (CO₂), chlorides, and high pressures. Our duplex tubing

2207 ステンレス鋼プレート、極限環境向けスーパーデュプレックスグレード

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
