耐食性の高力ステンレス鋼の精密管 ASTM A789
ASTM A789 / A789M covers the requirements for seamless and welded duplex stainless steel tubes for general corrosion-resistant service, with particular emphasis on resistance to stress corrosion cracking. This product combines the excellent toughness of austenitic stainless steel with the high strength of ferritic stainless steel, while offering superior resistance to chloride-induced pitting and crevice corrosion. This product covers common grades including UNS S31803,
熱加工ステンレス鋼丸管 304 304L 310S 321 熱加工した無縫管
Hot processed stainless steel round tube refers to seamless tubing manufactured through hot forming operations, where solid stainless steel billets are heated to approximately 1200°C (2190°F) and then pierced, rolled, and elongated to achieve the desired dimensions. This manufacturing method produces a tube with no longitudinal weld seam, offering uniform mechanical properties, consistent wall thickness, and superior pressure-holding capability. The hot processing method –

ホットロールSSSMLSパイプ ホット完成したシームレス・コンストラクションステンレス・ステール・ラウンド・チューブ
Hot Rolled Stainless Steel SMLS Pipe is manufactured by heating a solid stainless steel billet to approximately 1200°C (2200°F) and then rolling it through a series of mills to form a hollow tube. This high-temperature forming process allows for the production of large diameter, thick wall pipes that cannot be efficiently manufactured through cold drawing methods. Hot rolled seamless pipes are the backbone of heavy industrial piping systems, offering excellent mechanical
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
316 316L ステンレス鋼 無縫管 オステニティックニッケルクロムモリブデン合金鋼
316/316L Seamless Pipe - ASTM A312 TP316L Marine-grade Stainless Steel Pipe 316/316L stainless steel seamless pipe is an austenitic chromium-nickel-molybdenum alloy pipe known for its superior corrosion resistance, especially against chlorides and acidic environments. 316L is the low-carbon version of 316, offering better weldability and resistance to intergranular corrosion after welding. Both grades are widely used in marine, chemical, and pharmaceutical applications. Key
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.
