Stainless steel for the knife

Alloying

Knife blades are made. of high-strength steel, usually. alloyed with the following elements. Carbon gives the composition hardness, but reduces ductility. Chromium gives wear resistance, corrosion resistance, and improves the aesthetic appearance of the blade. Blades containing more than 13% of chromium are classified as stainless. Manganese can be used to achieve a fine grain structure of the alloy, which contributes to the hardening of the material. Molybdenum reduces brittleness and brittleness. Tungsten, which is used for tool steels, gives the blade red resistance, i .e. the ability not to lose its qualities when heated and subsequently cooled. .

Marking

The first number in the grade represents the carbon content in hundredths of a percent. For example, 10 means 0.10%. When there are no numbers at the beginning of the grade, the carbon fraction is more than 1%. Next comes the letter abbreviation. If there is no number after the letter, the element is less than 1%. The letter "A" means the minimum content of harmful sulfur, phosphorus.

Categories

Alloyed steel alloys according to GOST 4543-71 are divided into 3 categories: quality, high quality and the highest quality. The first category is indicated by the letter "A", the highest quality - by the letter "Sh" through the dash. For example, 12KhNZA - high quality, Z0GS-Sh - the highest quality. High-quality steel alloy has an allowable percentage of sulfur up to 0.025%, high-quality - up to 0.015%.
