Good quality of Q345B steel

Q345B steel is a Chinese standardized low alloy, medium tensile strength steel made with a hot-rolling process, and Q345B steel is used for a number of manufacturing purposes.

Q345B steel is steel with less than 0.2 percent of its composition made up of carbon, less than 0.55 percent of its composition made of silicon and several impurities (mostly sulfur, chromium and nickel). This particular grade of steel is a 'general purpose' manufacturing steel, used for sheet metal, light structural elements of household goods, and similar uses where it won't be used as a major structural component.

The density of Q345B steel is approximately 7.8 (where water is 1.0), and Q345B steel is commonly available in thicknesses ranging from 2 mm to 12.7 mm (12.7 mm is approximately half-inch thick plates), with sheets typically sold in 1 to 1.35 meter wide splits. By way of comparison, a 2 mm thick sheet that was 1 meter wide by 3 meters long would have a volume of 0.002 *1 * 3 or 0.006 cubic meters, and would have a mass of 0.006 * 7.8 = 0.0468 kilograms.
