What is JIS carbon steel SM490YA CS plate meaning

With the increase of temperature, the yield limit of JIS carbon steel SM490YA CS plate will decrease monotonically, but the tensile strength of JIS carbon steel SM490YA CS plate will rise to a high peak value at a certain temperature, and then decrease. This peak temperature is called the blue brittleness temperature of JIS carbon steel SM490YA CS plate. Near the blue brittleness temperature, the JIS carbon steel SM490YA CS plate strength increases and the plasticity decreases. The elongation and section shrinkage of JIS carbon steel SM490YA CS plate increase with the increase of temperature, but there is a low peak at the blue brittleness temperature. The blue brittleness temperature of low carbon steel ranges from 200 ℃ to 250 ℃. The blue brittleness of low alloy steel is not obvious as that of low carbon steel, and the blue brittleness temperature is higher.

JIS carbon steel SM490YA CS plate, Medium and heavy steel plate is a kind of steel plate with outstanding characteristics. First of all, there are many kinds of thickness of medium and heavy steel plate, which are generally relatively thick. Secondly, the thickness of medium and heavy steel plate is relatively thick, so it can be used for high strength application such as bridges. Thirdly, the corrosion resistance and wear resistance of medium and heavy steel plate are much better than ordinary steel plate.
