Corrosion Resistance
17-4 PH alloy corrosion resistance is superior to any other standard hardenable stainless steel. In most cases, its corrosion resistance is as much as 304. If there exists the risk of stress corrosion cracking, high curing temperature must be higher than 550℃.( The best temperature is 590℃. As for Chloride medium, the best tempering temperature is from 550 ℃ to 1022℃. As for H2S medium the best tempering temperature is from 590 ℃to 1094 ℃. The alloy in the static salty water easily suffers from polluting corrosion orcracking corrosion.
Machinability
We can treating the 17-4 PH alloy under hardening state by way of solution treatment or quenching water on mechanical processing. The material hardness changes according to the processing condition.
