For maximum oxidation resistance, Grade 446 Hydraulic Fittings should be welded with matching composition of alloy GTAW wire. The weld fillers developed for Type 446 Hydraulic Fittings can also provide a weld which is stronger and more oxidation resistant than the alloy base metal. 446 Stainless Steel Hydraulic Fittings is more difficult to machine than SS 304, where its machinability rating is 15 % – 21 % relative to steel. The nickel, chromium, molybdenum and copper levels of 446 Stainless Steel Forged Hydraulic Fittings provide excellent general corrosion resistance.
Restricted carbon plus columbium stabilization of 446 Stainless Steel Hydraulic Type Fittings permits welded fabrications to be used in corrosive environments, normally without post – weld heat treatment. At 33 % nickel, SS 446 Hydraulic Type Fittings has practical immunity to chloride stress corrosion cracking. SS 446 Forged Hydraulic Fittings is often chosen to solve SCC problems, which may occur with 316L stainless.
