Steel Casting Q345 - tambohotel

Introduction and application of Q345 low alloy steel - EB Q345 is a low-alloy steel widely used in Bridges, vehicles, ships, construction, pressure vessels, special equipment, etc. Q means yield strength and 345 means yield strength of this steel is 345MPa.Of the low alloy materials, Q345 is the most common. Q345 used to be called 16Mn. Structural Steels S235, S275, S355, S420 and Their PropertiesThe number in a structural steels name is its yield strength. It indicates the maximum load, in MPa, that does not end in plastic deformation. Stress above that value will deform the metal permanently. In S235 steels case, this value is 235 MPa. Anything below results in elastic deformation, meaning that your detail will regain its former
