What is the difference between bluing clad steel belt Q195 and Q235?

Play the difference between steel belt Q195 and Q235 bluing. Two kinds of materials, concrete is the difference between the carbon content. Also the hardness difference. Due to the gap on the tensile strength and elongation. General bluing of baotou steel belt Q195 average around 650 mpa/MM tensile strength, elongation at 3 - 5%; Q235 bluing dozen steel belt in the average strain of around 800 mpa/was. Also in 3 - elongation 5%, have the same kind of material of tensile strength in the process of production, tension and extension is inversely proportional to. Points from the material. Play with baotou steel, Q195, Q215, Q235, Q345, 20 # manganese steel. In baosteel's large factory, of course, there are other aluminum material 08, 195 l, etc.
