AISI 445 , EN 1.4621 , DIN X2CrNbCu21 ferritic stainless steel sheet and plate
Grade 445 is low carbon ferritic stainless steels conforming to UNS S44500.
This grade offers outstanding resistance to corrosion and is well suited for a wide range of applications,
typically used for hot water tanks and tubing, heat exchangers, solar collector panels, food processing
and handling equipment, sinks and architectural panels.
Grade 445 is stabilized with niobium to prevent sensitization and intergranular corrosion when welded.
This grade is not susceptible to chloride stress corrosion cracking.
The alloy cannot be strengthened by heat treatment as work hardening of ferrite is much less than for austenite.
