LORK is a special stainless steel manufacturer with 20 years of manufacturing experience.
17-4PH is one of the most popular and most commonly used stainless chromium-nickel alloy steels with copper additive, precipitation hardened with martensitic structure. It is characterized by high corrosion resistance while maintaining high strength properties, including hardness.
Steel can operate in the temperature range from -29 ºC to 343 ºC, while retaining relatively good parameters. In addition, the materials in this grade are characterized by relatively good ductility and their corrosion resistance is comparable to 1.4301 / X5CrNi18-10.
Bearing in mind that it is a precipitation hardened steel, it should be applied after supersaturation and aging. In the delivery condition +A, the products show no martensitic structure, resulting in significantly less corrosion resistance
