ASTM A335 P9 +ASME SA335 P9
ASTM A335 Pipe is a seamless ferritic alloy-steel Pipe for high temperature service.
ASTM A333 Gr.6 + ASME SA333 Gr.6
The main components of A333 seamless steel pipe include iron, carbon, chromium, nickel, manganese and other elements.
ASTM A335 P11+ASME SA335 P11
ASTM A335 Pipe is a seamless ferritic alloy-steel Pipe for high temperature service. Pipe of this specification are suitable for bending, flanging, and similar forming operations, and for fusion welding.
ASTM A335 P22+ ASME SA335 P22
12Cr1MoVG seamless steel pipe
Seamless steel pipe is made by perforating a whole round steel. It has no welds on the surface and a hollow cross-section structure. It is widely used in fluid transportation, machinery manufacturing and other fields.
15CrMoG Seamless Steel Pipe
2507 Duplex Stainless Steel Pipe
2507(UNS S32750) is an ultra-duplex stainless steel containing 25% chromium, 4% molybdenum and 7% nickel. It is designed for demanding applications that require excellent strength and corrosion resistance, such as chemical processes, petrochemicals and seawater equipment. The steel has excellent resistance to chloride stress corrosion cracking, high thermal conductivity and low coefficient of thermal expansion. High chromium, molybdenum and nickel levels provide excellent resistance to pitting, crevice corrosion and general corrosion.
904L Stainless Steel Pipe
Grade 904L is an unstable low carbon high alloy austenitic stainless steel. The addition of copper to this grade greatly increases its resistance to strong reducing acids, especially sulfuric acid. It is also highly resistant to chloride attack, including pitting/crevice corrosion and stress corrosion cracking.
444 Stainless Steel Pipe
444 stainless steel is a ferritic stainless steel, the national standard grade is 00 Cr18Mo2, its elements of ultra-low carbon nitrogen, chromium content of 18% and 2% molybdenum content, strong corrosion resistance. This type of stainless steel is usually stabilized by niobium or titanium, which can prevent intergranular corrosion after welding.
439 Stainless Steel Pipe
439 steel is in the ordinary ferrite material (430) on the basis of reducing the content of C, while adding Ti and other stabilizing elements, so that the steel intergranular corrosion resistance, formability and weldability are improved. Compared with the 304 steel, although the elongation is low (about 30%), but the strength, corrosion resistance, and corrosion resistance is better than 200 series materials.
430 Stainless Steel Pipe
430 grade is a ferritic, straight chromium, non-hardenable grade that combines good corrosion resistance and formability characteristics with useful mechanical properties. Its resistance to nitric acid attack allows it to be used in specific chemical applications, but automotive trim and electrical components represent its largest areas of application.
