Stainless steel AISI 347 / EN 1.4550 / 08Х18Н12Б
AISI 347 steel is a corrosion-resistant stabilized chromium-nickel austenitic stainless steel.
Delivery form:
– Steel sheets and strips.
– Shaped and long products.
– Pipes and elements of their connection.
– Circles and blanks.
Features of AISI 347
Taking into account the purpose, aggressiveness of working environments and operating conditions, hardening, step processing, annealing to relieve stress or stabilization can be applied to products.
Fields of application
The price of stainless steel is fully consistent with its properties, which are taken into account in the manufacture of products for various purposes. These can be:
– Separate parts and whole structures welded using spot welding.
– Elements of significant viscosity, for refrigeration units, machines and aircraft operating at temperatures up to -253 degrees.
– Parts operating in aggressive environments with temperatures from -196 to +600 degrees.
– Welding equipment for work in a particularly aggressive environment of acids, alkalis and salts.
Pipes, rolled products, stainless steel sheet aisi347 are also used for the manufacture of parts, equipment, joints and welded structures operating in a radioactive environment.
