How S235JR Steel Plate is Made and Its Unique Characteristics

S235JR steel plate is a popular low-carbon structural steel that is used in a wide variety of industrial and construction applications.

Raw Materials: The raw materials used to make S235JR steel plate include iron ore, limestone, and coke. These materials are melted in a blast furnace at high temperatures to produce molten iron, which is then refined into steel.

Rolling Process: Once the steel has been produced, it is rolled into large flat sheets of steel called plates. The rolling process involves passing the steel through pairs of rollers to reduce its thickness and shape it into the desired size and shape.

Heat Treatment: After the rolling process, S235JR steel plate undergoes heat treatment to improve its mechanical properties. This involves heating the steel to a specific temperature and then cooling it rapidly to harden it. The heat treatment process can also enhance the steel's toughness and resistance to wear and tear.

Chemical Composition: S235JR steel plate has a low carbon composition, which makes it more cost-effective than other types of steel while maintaining similar mechanical properties. It also contains small amounts of other elements such as manganese, phosphorus, sulfur, and silicon, which contribute to its overall strength and durability.

Weldability: S235JR steel plate exhibits good weldability properties, making it easy to fabricate and customize using standard welding techniques like arc welding and gas welding.

Corrosion Resistance: While S235JR steel plate offers moderate corrosion resistance, it is not as corrosion-resistant as other types of steel. Proper surface preparation and coatings may be required to protect the steel from corrosion in certain environments.
