According to the composition, it can be divided into Cr-Mn-Ni (200 series), Cr-Ni series (300 series), Cr series (400 series), heat-resistant chromium alloy steel (500 series) and precipitation hardening series (600 series). 200 series: chromium-manganese-nickel 201, 202, etc .: Manganese-nickel substitutes have relatively poor corrosion resistance, and are widely used as cheap substitutes for the

1. What is quenching? The quenching of steel is to heat the steel to a temperature above the critical temperature Ac3 (hypoeutectoid steel) or Ac1 (hypereutectoid steel), hold it for a period to fully or partially austenite, and then cool it at a rate greater than the critical cooling rate The heat treatment process

Stainless steel is the abbreviation of stainless acid-resistant steel. Steels that are resistant to weakly corrosive media such as air, steam, and water, or stainless steel are called stainless steel; and chemical-resistant media (chemical etching such as acid, alkali, salt, etc.) The type of steel is called acid-resistant steel. Ordinary stainless steel is generally not

What is stainless steel? Stainless steel is a type of steel. Steel refers to those containing less than 2% carbon (C), which is called steel, and more than 2% is iron. Adding chromium (Cr), nickel (Ni), manganese (Mn), silicon (Si), titanium (Ti), molybdenum (Mo) and other alloy elements during the smelting process of the
