sus630 stainless steel
SUS630 stainless steel (17-4PH / 1.4542) is one of the most popular and most commonly used stainless chromium-nickel alloy steels, copper added, precipitation hardened, with a martensitic structure. It is characterized by high corrosion resistance while maintaining high strength properties, including hardness. Steel can operate in a temperature range of -29°C to 343°C while retaining relatively good parameters.
17-4PH, sus630 and X5CrNiCuNb16-4 / 1.4542 are available as round bar, plate, flat bar and cold rolled strip. The material is widely used in heavy machine components, bushings, turbine blades, couplings, screws, drive shafts, nuts, measuring devices in the aerospace, marine, paper, energy, offshore and food industries.
