17-4 PH is a martensitic, precipitation hardening, stainless steel that is widely accepted in a wide range of industries. Through a very useful combination of high strength and hardness, excellent corrosion resistance and ease of heat treatment, this alloy becomes important to designers and engineers. Manufacture of 17-4 PH Stainless steel follows many methods established for the common grades of stainless steel. The material provides excellent welding properties, can be forged or cast and processes well. The normal process of hardening requires only a temperature of 482 – 624 °C (900 – 1150 °F) and is finished with air cooling, which virtually eliminates scale and deformation. Additional properties include high resistance to cracking, good mechanical properties in the radial direction and proven resistance to stress corrosion cracking in marine environments. Through a simple and cheap manufacturing process, it can sometimes be profitable to replace low-alloy materials with 17-4 PH stainless steel.
17-4PH can be provided with different heat treatments. Below table shows the conditions with respective strength values.
In the beginning of 2022, Livallco started a collaboration with AK Steel International, which is a world-leading stockist of 17-4Ph. Livallco is from then on an exclusive dealer of AK Steels International’s products in Sweden.
