Steel is an iron-carbon alloy containing between 0.04% and 2.3% carbon. We usually refer to it as iron and steel, with a melting point of 1515 degrees. In order to ensure its toughness and plasticity, the carbon content generally does not exceed 1.7%. In addition to iron and carbon, the main elements of steel include silicon, manganese, sulfur, phosphorus, etc., which refer to iron-carbon alloys containing less than 2% carbon. According to different ingredients, it can be divided into carbon steel and alloy steel. According to performance and use, it can be divided into structural steel, tool steel and special performance steel. There are various methods for classifying steel. The main methods are as follows: 1.
Chromium is the basic element for obtaining corrosion resistance of stainless steel (all stainless steel elements have a common characteristic, that is, the chromium content is above 10.5%). When the chromium content in steel reaches about 12%, chromium and The action of oxygen in the corrosive medium forms a very thin oxide film (self-passivation film) on the steel surface, which prevents further corrosion of the steel matrix. In addition to chromium, commonly used alloying elements are nickel, molybdenum, titanium, niobium, copper, nitrogen, etc., to meet the requirements of stainless steel structure and performance for various purposes. Stainless steel is usually divided into matrix structures: 1. Iron
