Strength and application of JIS carbon steel SM490B CS plate

JIS carbon steel SM490B CS plate, Low alloy steel plate is a general designation, mainly refers to the steel plate with alloy content less than 3.5%. Alloy steel in the market is distinguished by the total amount of alloy elements, mainly including low alloy steel, medium alloy steel and high alloy steel. When the total alloy amount is less than 3.5%, it is called low alloy steel; if the total alloy amount is 5-10%, it is medium alloy steel; and when the total alloy amount is more than 10%, it is high alloy steel.
