Use of a chromium steel with martensitic structure and carbide inclusions

摘要

Use of a martensitic, in particular chromium steel cobalt-free with carbide insert of a particle size of not more than 15 μm from 0,50 to 0,78% carbon, 0,20 to 1,30% silicon, 0,15 to 0,80% nickel, 0,30 to 1,00% manganese, 0,01 to 0,035% sulfur, 16 to 18% chromium, 1,25 to 1,50% molybdenum, 0,001 to 0,8% tungsten, 0,04 to 0,08% nitrogen, 0,15 to 0,20% vanadium, 0,001 to 0,04% titanium, 0,001 to 0,04% niobium, 0,001 to 0,03% aluminum, 0,02 to 0,5% copper, 0,001 to 0,04% of boron, and the balance being iron and impurities as a "pitting" - and friction wear resistant material for the life - and and luxury products industry as well as for surgical instruments.
