What Is MS Plate?
Mild steel is an iron-carbon alloy with a carbon content ranging from 0.0218% to 2.11%. It is also called as carbon steel.
According to the carbon content in the material, we generally refer to steel with a carbon content of 0.06% to 0.25% as low-carbon steel; steel with a carbon content of 0.25% to 0.55% as medium-carbon steel; and steel with a carbon content of 0.60% to 1.03% as high-carbon steel.

(1) When the carbon content in steel exceeds 0.23%, the welding performance of the steel deteriorates. Therefore, low-alloy structural steels used for welding generally have a carbon content of no more than 0.20%.
(2) When the carbon content in steel is below 0.8%, as the carbon content increases, the strength and hardness of the steel increase while its plasticity and toughness decrease.
(3) When the carbon content is above 1.0%, as the carbon content increases, the strength of steel decreases instead. With an increase in carbon content, welding performance worsens (the special weldability can significantly decrease with steels having a higher than 0.3% carbon), cold brittleness and aging sensitivity increase, resistance to air rust corrosion decreases, making high-carbon steels susceptible to rusting when exposed to outdoor storage.
Generally, it also contains small amounts of silicon, manganese, sulfur and phosphorus. The higher the carbon content in carbon steel, the greater its hardness and strength but lower its ductility.
Types of MS Plate
(1) According to their uses, carbon steel can be divided into three categories: carbon structural steel, carbon tool steel, and easy-to-cut structural steel. Carbon structural steel is further divided into two types: engineering construction steel and machine manufacturing structural steel;
(2) According to the smelting method, it can be divided into open hearth steel and converter steel;
(3) According to the deoxidation method, it can be divided into boiling steel (F), calm-steel (Z), semi-calm-steel (b), and special calm-steel (TZ);
(4) According to the carbon content, carbon steels can be classified as low-carbon steels (WC ≤ 0.25%), medium-carbon steels (WC 0.25% – 0.6%), and high-carbon steels (WC> 0.6%);
(5) Based on quality of the material, carbon steels are categorized as ordinary carbon steels(high in phosphorus & sulfur content), high-quality carbon steels(low in phosphorus & sulfur content), advanced high-quality steels(even lower in phosphorus & sulfur content than previous category )and special grade high-quality steels.
