Classification of stainless steel series

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

Silica Sol casting

The Silica Sol casting technology belongs to investment casting, which is a casting technology with little or no cutting. It is an excellent technique in the casting industry. The quality of the processed products is high and can reach the standard of first-class castings. The biggest advantage is a high dimensional accuracy and surface

The role of various elements of stainless steel

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 the difference between 304, 304L, 316, 316L

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
