Low - Although 1.4104, contains 17 % chromium, the corrosion resistance of this steel is severely compromised by the addition of sulphur. This is particularly true when exposed to environments that promote pitting and crevice corrosion. PRE = 16.16 – 19.48
Very Good -The machinability of this grade of stainless steel is superior to other 12 and 17 % chromium steels as a result of the sulphur addition.
Soft annealing: 750-850°C (Cooling in furnace, air) - Hardening: 950-1050°C in polymer, oil, air - Tempering: 550-650°C air
It is formable at 800-1100°C
Quenched and tempered QT 650
Poor - In general, 1.4104 is not welded, other than occasionally being friction or resistance welded.
