654SMO(EN 1.4652/UNSS32654) is a special stainless steel containing a high percentage of Nickel and Chromium containing 7% Molybdenum,which is the highest corrision restistance in the world.
It has a fairly high electrical conductivity among wrought superaustenitic stainless steels. In addition, it has the lowest thermal conductivity and very high tensile strength.
654SMo (S32654, 1.4652) super austenitic stainless steel features very good local corrosion resistance, good pitting resistance and good stress corrosion resistance under seawater, aeration, gap and low speed scouring conditions. It can be used as a good substitute to nickel-based alloys and titanium alloys. When it comes to high-temperature resistance or corrosion resistance, it is also superior to 904L and 254SMo.
654SMO seamless super stainless steel tube is a high-performance, super austenitic stainless steel product known for its exceptional corrosion resistance and high strength. It is an advanced alloy often used in extremely demanding corrosive environments.① STANDARD: ASTM A213 A249,A267,A270,EN10216-5...② OD RANGE : 6-257MM③ THICKNESS RANGE: 1-35MM
TP347H Seamless Stainless Steel Pipe are high-performance austenitic stainless steel tubes stabilised with niobium, specifically designed for elevated temperature applications and enhanced creep resistance. ① STANDARD: ASTM A312/ ASTM A249/ ASTM A269/ EN10216-5/GOST 9940 /GOST 9941...② OD RANGE : 6-1016 MM③ THICKNESS RANGE: 1-65 MM
Seamless Stainless Steel U-tube is a specific type of heat exchanger tube that is bent into a"U"shape after the manufacturing process. It is crafted from a single, solid billet of stainless steel and, like other seamless tubes, has no weld joint. This seamless construction is crucial for maintaining structural integrity and reliability, especially in high-stress and corrosive environments. The unique U-shape allows for thermal expansion and contraction, making it ideal for shell and tube heat exchangers. It enables a single-pass fluid flow on the shell side and a multi-pass flow on the tube side, maximizing heat exchange efficiency and reducing the overall footprint of the heat exchanger.① STANDARD: ASTM A213② OD RANGE : 6-50.8MM③ THICKNESS RANGE: 0.5-9MM④ U-BEND & STRAIGHT
TP316Ti /1.4571/UNSS31635 Seamless Stainless Steel Tube is a high-performance tubing solutions known for their excellent resistance to corrosion, heat, and mechanical stress. These tubes are specially alloyed with titanium to enhance strength and stability at elevated temperatures, making them suitable for demanding environments. ① STANDARD: ASTM A213/ EN10216-5/ ASTM A249/ ASTM A269/ GOST 9940 /GOST 9941...② OD RANGE : 6-257MM③ THICKNESS RANGE: 1-35 MM
