Description
Q345D is a low alloy steel. Low alloy steel is an alloy steel with a total alloying element content of less than 5%. Compared with carbon steel, low alloy steel intentionally adds one or more types of steel to the steel in order to improve its properties. alloy element. When the amount of alloy added exceeds the normal content of carbon steel produced by normal production methods, the steel is called alloy steel. When the total alloy content is less than 5%, it is called low alloy steel. Ordinary alloy steel is generally less than 3.5%. When the alloy content is between 5-10%, it is called medium alloy steel. When the alloy content is greater than 10%, it is called high alloy steel. Q represents the yield of this material, and the following 345 refers to the yield value of this material, which is around 345. And as the thickness of the material increases, its yield value decreases.
