1.4307 ステンレス鋼シームレス パイプ EN DIN 低炭素オーステナイト グレード
1.4307 seamless stainless pipe is the European (EN/DIN) designation for a low carbon austenitic stainless steel grade, equivalent to UNS S30403 and ASTM A312 TP304L. This grade is specifically designed for applications requiring excellent corrosion resistance combined with superior weldability, particularly where post-weld heat treatment is not practical or desired. The "1.4307" designation follows the EN 10088 and EN 10216-5 standards, which govern seamless stainless steel
酸耐性SS316シームレスパイプ 低炭素 硫黄耐性
Acid-resistant 316 seamless tube is a premium austenitic stainless steel product specifically designed for service in acidic and chemically aggressive environments. The addition of 2-3% molybdenum distinguishes this grade from standard 304, providing significantly enhanced resistance to a wide range of acids, including sulfuric, phosphoric, acetic, and organic acids, as well as chloride-induced pitting and crevice corrosion. The seamless manufacturing process ensures uniform
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
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
TP316L SMLS パイプ 低炭素モリブデンム軸承シームレスパイプ
TP316L SMLS pipe is a low carbon, molybdenum-bearing austenitic seamless stainless steel pipe designed for superior corrosion resistance in aggressive environments. The "TP" designation indicates that the pipe meets the requirements of ASTM A312, the standard specification for seamless, welded, and heavily cold worked austenitic stainless steel pipes. "SMLS" denotes seamless construction, meaning no longitudinal weld seam exists. The low carbon content (0.030% maximum)
スーパーデュプレックス 2507 不同鋼板 ASTM A240 高強度耐腐食性
ASTM A240 Super Duplex 2507 (UNS S32750) is a high-strength, corrosion-resistant stainless steel plate with a ferritic-austenitic microstructure. It offers approximately three times the yield strength of 316L and a PREN value of 40 or higher, providing exceptional resistance to pitting, crevice corrosion, and chloride stress corrosion cracking. Ideal for the most demanding environments, Super Duplex 2507 is widely used in offshore platforms, chemical processing, seawater

S32750 スーパーデュプレックスチューブ ASTM A790
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.
