Product Description

Manufacture Hot Rolled Forged Alloy Steel Round Bar 1.4542 


1: 17-4PH steel introduction
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.
