Steel grade 1.4462 ( also called UNS S31803 / S32205, F51 and SS2377 ) is a stainless acid resistant duplex steel with high strength and extremely good corrosion properties. Thanks to the duplex structure of steel ( austenitic-ferritic ) and high chromium and molybdenum content, it has a very high resistance to pitting corrosion, crevice corrosion, uniform corrosion, corrosion fatigue and stress corrosion cracking. It also has high energy absorption power and low thermal expansion.
Two-phase duplex steel with ferritic-austenitic structure resistant to high temperatures , working in NaCl , CaCl2, LiCl2, high chromium - Cr, Molybdenum - Mo and Nitrogen - N content, resistant to high temperatures .
Weldability
1.4462 has good weldability and can be welded by most common welding methods eg . Shielded metal arc welding, Gas tungsten arc welding, Plasma arc welding and Submerged arc welding. You will be using Avesta Welding 2205 when welding or doing something similar to filler metal . Steel can be formed both cold and hot. Processing is done with high speed tools .
