1.4568 / 17-7 PH – DIN X7CrNiAl17-7

1.4568 is an age hardened stainless steel with the highest Chromium and Nickel content compared to 15-5 and 17-4 PHs. It has excellent strength property, high hardness and elasticity, good corrosion resistance and resistance to high temperatures and deformation.

In terms of chemical composition, corrosion resistance is equal to AISI 301 / 1.4310 steel. It is a much better choice for parts and components subject to fatigue in terms of mechanical properties. 1.4568 has an austenitic structure in the annealed state, transforms into martensite after aging, increasing its strength properties with the achievement of magnetic properties.

1.4568 is used on valve parts, tanks, springs, spring washers, food knives, diaphragms, low and high temperature parts, heat exchangers, special fittings and fittings, machine constructions and components. It is designed in the form of strips, wires, sheets and rods for the steel, aerospace, petroleum, chemical and petrochemical industries, energy, food and cryogenic industries.
