Stainless steel (Stainless Steel) is the abbreviation of stainless acid-resistant steel, and the steel that is resistant to weak corrosive media such as air, steam, water or has stainless steel is called stainless steel; Steel that is resistant to chemical corrosion media (acid, alkali, salt and other chemical erosion) is called acid-resistant steel.

Carbon steel is an iron-carbon alloy with a carbon content of 0.0218%~2.11%. Also called carbon steel. It generally contains small amounts of silicon, manganese, sulfur and phosphorus.

2. Different classifications:

Stainless steel: according to the microstructure state, it is divided into: martensitic steel, ferritic steel, austenitic steel, austenitic-ferritic (duplex) stainless steel and precipitation hardening stainless steel. In addition, it can be divided into chromium stainless steel, chromium-nickel stainless steel and chromium-manganese nitrogen stainless steel according to the composition.

Carbon steel: according to the use, carbon steel can be divided into carbon structural steel, carbon tool steel and easy cutting structural steel three categories, carbon structural steel is divided into engineering construction steel and machine manufacturing structural steel two; According to the smelting method, it can be divided into open-hearth furnace steel and converter steel.

3. Different uses:

Stainless steel: widely used in curtain walls, side walls, roofs and other building purposes, among which 316 stainless steel is often used in highly aggressive industrial or marine atmosphere.

Carbon steel: used in the manufacture of various springs, wheel rims, low-speed wheels, to make tools that are not affected by impact. Such as files, scrapers, razors, measuring tools.
