These additions make the steel free machining for ease of manufacture but can reduce the iso 3506-1 resistance under certain conditions such as marine environments chloride pitting attack risk Grade A2 does not specify molybdenum additions but allows these Normally the deliberate addition of molybdenum makes the grade A4.


Notes The mechanical property limits are minima. A1 Designed for machining Has higher sulphur content iso 3506-1 therefore lower corrosion resistance.

F1 can, if need be, replace steels of grade A2 and A3 and be used in an environment with a higher chloride content.
