UNS S31803 シームレス パイプ ASTM A789 4" スケジュール 40 ステンレス鋼パイプ
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
縫い目なし 溶接 2205 デュプレックスステンレス鋼管 ASTM A790
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.

ASTM A789 UNS S32750 オフショア潜水用デュプレックスステンレス鋼管
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
スーパー二相ステンレス鋼板高強度耐食性
Super duplex stainless steel plate is a high-performance material that combines the advantageous properties of both austenitic and ferritic stainless steel microstructures. With a balanced duplex microstructure (approximately 50% ferrite / 50% austenite), super duplex grades offer approximately twice the yield strength of conventional austenitic stainless steels (e.g., 304, 316) while providing exceptional resistance to pitting, crevice corrosion, and stress corrosion
構造 角形ステンレス鋼管溶接高強度ステンレス鋼 RHS
The Structural Stainless Steel Rectangular Hollow Section (RHS) is a cold-formed or hot-finished welded hollow profile specifically engineered for load-bearing applications in construction, infrastructure, and industrial projects. Manufactured from high-strength austenitic or duplex stainless steel grades, this section offers an exceptional combination of high strength-to-weight ratio, corrosion resistance, fire resistance, and long-term durability. Unlike decorative or
オイル&ガス デュプレックスステンレス鋼管 NACE MR0175 2205 2507 酸性サービス用
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
表 10 溶接式不鋼管 角角 端 焼き 漬け
The Large Diameter Stainless Steel Welded Pipe is manufactured by roll forming high-quality stainless steel plate or coil into a cylindrical shape and welding the longitudinal seam using advanced TIG, plasma, or submerged arc welding (SAW) technology. Designed for applications requiring high flow capacity, structural strength, and corrosion resistance, this pipe is available in diameters exceeding the limits of seamless manufacturing. It offers a cost-effective solution for
