ASTM A249 ống thép không gỉ austenit hàn cho dịch vụ nồi hơi trao đổi nhiệt
ASTM A249 / A249M is a standard specification issued by ASTM International for welded austenitic stainless steel tubes used in boilers, superheaters, heat exchangers, condensers, and hydraulic systems. These tubes are manufactured using GTAW or ERW processes and are supplied in the solution annealed condition to ensure corrosion resistance and high-temperature strength. This product covers common grades such as TP304, TP304L, and TP304H, making it particularly suitable for
Super Duplex Stainless Steel Plate Độ bền cao chống ăn mòn
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
ASTM A249 ASME SA249 ống thép không gỉ hàn cho máy trao đổi nhiệt
Welded stainless steel tube is manufactured by forming stainless steel strip into a tube shape and longitudinally welding the seam using automatic GTAW (Tungsten Inert Gas) or laser welding processes. After welding, the tube undergoes solution annealing and NDT testing to ensure weld integrity and consistent corrosion resistance. Welded tubes offer a cost-effective alternative to seamless tubes for applications not requiring the extreme pressure ratings or critical service
Phần rỗng hình chữ nhật bằng thép không gỉ lớp 316 được hàn theo tiêu chuẩn ASTM A554
Marine grade rectangular hollow section (RHS) refers to 316 stainless steel rectangular tubing specifically designed for applications in coastal, offshore, and marine environments where standard 304 stainless steel would be susceptible to pitting and corrosion from chloride exposure. The addition of 2-3% molybdenum to the 316 grade provides significantly enhanced resistance to pitting, crevice corrosion, and stress corrosion cracking in seawater, salt spray, and chloride-rich
316 Thép không gỉ ống hình chữ nhật ASTM A554 hình chữ nhật phần rỗng
316 stainless steel rectangular tubing is the premium choice for applications requiring superior corrosion resistance, especially in chloride-rich environments such as coastal areas, marine settings, and chemical processing facilities. The addition of molybdenum (2-3%) gives 316 significantly better resistance to pitting, crevice corrosion, and stress corrosion cracking compared to 304 stainless steel. This rectangular hollow section (RHS) is manufactured to ASTM A554

Tấm thép không gỉ 2207, Lớp siêu song công cho môi trường khắc nghiệt
Ống thép không gỉ song công áp suất cao 550 MPa Độ bền năng suất Chống ăn mòn
High pressure duplex stainless steel pipe is specifically designed and manufactured to withstand extreme internal pressures while maintaining structural integrity and corrosion resistance. The unique two-phase microstructure (austenite + ferrite) provides approximately twice the yield strength of standard austenitic stainless steels such as 304 and 316, allowing for significantly thinner wall sections at equivalent pressure ratings. Our high pressure duplex pipes are produced
Super Duplex 2507 Bảng thép không gỉ ASTM A240 Kháng ăn mòn cường độ cao
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
