S ： ≤0.030
P ： ≤0.035
●It heats up very quickly when polished.
●440C annealing temperature is very low, hardness can usually reach hrc45-54
●If the cryogenic treatment, the hardness can reach hrc56-58.
●It is mainly used to manufacture bearing parts which work in corrosive environment and without lubrication and strong oxidizing atmosphere.
●Can be used to make high-quality knives, such as medical scalpel, scissors, nozzles, bearings, etc.
