Description

The machinability of 1.4104 (X14CrMoS17) is far superior to that of the ferritic 17% chromium steel, 1.4016 as a result of the controlled sulphur addition to this grade of steel. The addition of sulphur however reduces the resistance to corrosion, and as such 1.4016 is significantly more resistant to corrosion than 1.4104, despite their similar chromium contents. It should be noted that as a result of the sulphur addition, neither minimum impact properties, nor elevated temperature properties are specified.

Corrosion properties

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

General machinability

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.

Heat Treatment

Soft annealing: 750-850°C (Cooling in furnace, air) - Hardening: 950-1050°C in polymer, oil, air - Tempering: 550-650°C air

Hot forming

It is formable at 800-1100°C

Processing history

Quenched and tempered QT 650

Welding

Poor - In general, 1.4104 is not welded, other than occasionally being friction or resistance welded.
