The common technological properties of JIS SM490YB plates

Heat treatment is a very important process to improve the performance of JIS SM490YB plates etc. metal materials. The process of heating, heat preservation and cooling the steel in solid state to obtain the required structure and properties.

SS400 is Japanese steel, equivalent to Q235 steel (also known as A3 steel). JIS SM490YB plates, Structural steels in foreign standards are often classified according to tensile strength, such as SS400 (which is indicated in Japan), where 400 means the minimum value of tensile strength σb is 400MPa. The yield point of Q235 is more than 235 MPa, while that of SS400 is 245 MPa.

In October, the demand for finished products improved significantly, breaking through the high of 4.4 million tons per week, and the price of black products went up overall. Among them, coke performed particularly well under the stimulus of downstream shortages and high molten iron output. It wasn't until early November that coke futures prices fell from a high level due to high disk premiums. After six rounds of increases, the spot price also began to weaken. Downstream steel mills were more resistant to the seventh round of increases.
