ASTM A312 / A213 / A268 TP 446 Pipes,WNR 1.4762 super ferrtic stainless steel tubes for heat exchanger
SPEZILLA is one of leading manufacturers of high quality Stainless Steel 446 Pipes and Tubes which find application across diverse sectors. We offer qualitative SS 446 Pipes and Tubes in different sizes and shapes that are being designed as per the national and international standard quality of raw materials. Also known as UNS S44600, these pipes and tubes are non-hardenable and high chromium stainless steel by means of having remarkable corrosion resistance. Alloy 446 having an excellent resistance to: Corrosion scaling, Abrasion, Sulfidizing atmospheres, Corrosion and oxidation. Relatively referred as WNR 1.4762 / 3, our 446 Stainless Steel are being offered at market leading prices to our valuable customers. Our Stainless Steel 446 Seamless Pipes can also be offered in customized length sizes and shapes to our esteemed clients. These SS 446 Welded Tubes can also be fabricated and machined to meet up the piping needs of our clients.
APPLICATIONS:
Grade 446 has excellent oxidation resistance in high temperatures, and composed by extra-low carbon Ferritic structure, so it has excellent in workability compared with conventional similar grades. Due to this properties, the typical applications for Grade 446 include:
Automotive exhaust systems (manifolds, exhaust pipes, converters, front and tail pipes, converters, mufflers and other components)
Heat exchangers
Catalytic converter systems
Culverts
Home heating systems
Automotive thermostats
Fuel filters
Farm equipment components
Electrical transformer cases
