SS400 steel is a structural hot rolled steel in the form of plates, sheets and strips for general structural applications. SS400 carbon steel with proper tensile strength and toughness, good plasticity, welding performance and processing property.
The Chemical Composition of SS400 Steels as under:
Carbon (C) is not identified in the standard.
Manganese (Mn) is not identified in the standard.
Maximum percentage of Phosphorous (P) is 0.050 percent.
Maximum percentage of Sulphur (S) is 0.050 percent.
Remaining is iron (Fe) percentage and with few negligible impurities.
