Castle Metals stocks a wide range of Stainless 17Cr-4Ni in bar and angle, distributed globally from our distribution centers in the U.S., Canada, Mexico, U.K, Singapore, and Shanghai. Customers calling for 17Cr-4Ni a lot of times are upset about dealing with fluctuations in their build schedules. Sometimes, we find that custom stocking programs help our customers react faster to changes.
Stainless Steel 17Cr-4Ni is a Martensitic stainless with high strength, corrosion resistance and hardness obtained by low temperature heat treatment. It contains slightly higher chromium content than other Martensitic grades. Distortion and scaling are minimized. Buying this product in the age-hardened condition also saves the time and additional expense of sending parts out for heat treatment.
