SS400 ASTMA36 H Beam Steel

Is SS400 mild steel or carbon steel?

SS400 is a type of carbon steel. It is commonly used for structural purposes and has a relatively low carbon content, making it milder in comparison to some other types of carbon steel.

Is SS400 same as A36?

Steel grades ASTM A36 and SS400 under JIS G3101 both are common used carbon structure steels,mild steels.When rolling steel plates ASTM Grade A36,As rolled or Controlled rolled is ok for thickness belows 40mm (1.5inch) normally.If above 40mm (1.5inch),customers can choose Normalized for improve steel property.Stee plates SS400 is also the same.

Carbon steel plate usually been considered as the steel that does not contain much alloy steel elements. Generally elements are C, Mn, P, S, Si, besides these there are no minimum limits for elements of Al, Cr, Ni, Mo, V etc.

Carbon steel plates are available in different grades depending on the carbon content and strength.

There are low, medium, and high carbon steel plates. The more carbon content, the more durable and stronger the plate becomes. There are further sub-categories depending on thickness and usage as well as the formation process. Usually carbon steel plates vary from 0.4 mm to 80 mm in thickness and 1000 mm to 45000 mm width, and they can be of length up to 18 meters. But the length is customizable which helps the customers to put them into various applications. One can also make cold rolled steel coils from them.
