¿Cuál es la diferencia entre acero al carbono y acero inoxidable??
We use a lot of precision parts are stainless steel material. it has a high hardness, strength and corrosion resistance, and shiny very good-looking. In fact, in addition to stainless steel, carbon steel is also very widely used in industry. So do you know the difference?
The difference between the stainless steel and carbon steel
(1) Corrosion and wear resistance
El acero inoxidable es una aleación resistente a la corrosión por medios débilmente corrosivos como el aire., vapor y agua y medios químicamente agresivos como ácidos, álcalis y sales. Y esta función se atribuye principalmente a la adición del elemento inoxidable. – cromo. Cuando el contenido de cromo es mayor que 12%, la superficie del acero inoxidable formará una capa de película oxidada, comúnmente conocida como película de pasivación, con esta capa de película oxidada no será fácil de disolver en ciertos medios, juega un buen papel de aislamiento, tiene una fuerte resistencia a la corrosión.
El acero al carbono se refiere al contenido de carbono de menos de 2.11% de la aleación hierro-carbono, también conocido como acero al carbono, su dureza es mucho mayor que la del acero inoxidable, pero el peso es mayor, la plasticidad es menor, the typical “too rigid and easy to fold”, fácil de oxidar.
(2) different composition
Stainless steel (Stainless Steel) is the abbreviation of stainless acid-resistant steel, air, steam, water and other weak corrosive media. And will be resistant to chemical corrosive media (acids, alkalis, salts and other chemical impregnation) corrosion of the steel is called acid-resistant steel.
Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. Also called carbon steel. It also generally contains small amounts of silicon, manganese, sulfur, and phosphorus.
(3) Cost
Another important consideration is the cost.
Although different steels have different costs, stainless steel is generally more expensive than carbon steel. Largely due to the addition of various alloying elements, such as chromium, nickel, and manganese, to stainless steel.
Compared to carbon steel, stainless steel has a large number of other alloys mixed in and more expensive . On the other hand, carbon steel mainly consists of relatively cheap elements of iron and carbon.
If you are on a tight budget for your project, then carbon steel may be the best option.
