Use of a chromium steel with a martensitic structure and inclusions of carbides

摘要

Use of a martensitic chromium steel containing 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 to 0.8% 0.001 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 0.05% copper 0.001 to 0.04% boron balance iron including impurities by melting, as material resistant to contamination or sea water or as a low material wear to the food and beverage industry for surgical instruments such as scalpels and blades, as material for making knives filleting for the preparation of fish and food and beverage industries as well as to make industrial needles.
