Mild Steel and Stainless Steel

Mild Steel and Stainless Steel Composition for Application


So many steel are used for spare part industry and for car. Each kind of steel should be used for certain purpose. Not only looking of steel become better to use, like stainless steel that is stand to corrode but stainless steel is bad to place on hot area. Stainless steel easily to deform cause of heat and stainless steel more elastic compare to carbon steel.

Stainless Steel actually an alloy steel that contain minimum 11.5 % of chromium, so stainless steel wiil stand to corrode. Stainless steel better use in humid environment because stainless steel will stand to this environment and stay along time without corrosion. Stainless steel have sufficient amount of chromium substance on the surface so that passive film of chromium oxide form on the surface which prevent to further corrosion.


Carbon steel is sometimes referred to as mild steel or plain carbon steel. American iron steel Institute defines that carbon steel have no more than 2% of carbon and no other appreciable alloying element. Carbon steel make up the the largest part of steel production and is used in vast of application.

Usually carbon steel are stiff and strong, this kind of steel suitable as engine material that is not easily to deform cause of engine heat. Carbon steel also exhibit of ferromagnetism, so carbon steel can be used as motors and electrical appliances. But carbon steel have poor resistance to corrode so this steel is not suitable placed on humid environment.
