Stainless martensitic • precipitation hardening steel • stainless ferritic — Our answer to your needs
Ferritic stainless 439, 441, 445
A series of grades which compete with 304 or 304L in corrosion resistance. The absence of nickel produces a lower cost alternative. The ferritic structure gives excellent deep drawability and stress corrosion cracking resistance but disadvantages in welding of thick sections and stretch forming.
Equivalent EN and UNS grade designations: 1.4510, 1.4509, 1.4621, 1.4622, 1.4611, S43035, S43940, S44500
These grades combine the following characteristics:
Applications which illustrate these features include:
Exhaust systems, washing machine tubs, cladding, wall panels, roofing, handrails, catering equipment, water tubing,
sugar processing, fuel cells, portable pizza ovens, lifts.
Hot and cold rolled stainless steel strip, coil, sheet and plate
