09CuPCrNi-A weathering steel plate containing machine parts steel is widely used in the machinery manufacturing industry and a larger amount of steel. Common machine zero car, tractor, machine tools, power station equipment, mining machinery and other machines on the shaft, gears, connecting rods, springs, fasteners, bearings, etc..
Machine parts in the work of tensile, compression, bending, shear, torsion, impact, vibration, friction and other forces, sometimes several forces at the same time.
These forces can produce a variety of stresses on the machine parts, such as tensile stress, compressive stress, shear stress, etc., the size of the stress can be constant or alternating; loading can be gradual or sudden.
Most of the working temperature range of machine parts is between -50 ~ 100 ℃, but also by the atmosphere, water, lubricants and other media corrosion.
Machine parts are often subjected to cold thermoplastic processing such as forging, rolling, extruding, drawing and other cold thermoplastic processing and turning, milling, planing, grinding and other cutting processes in the manufacturing process.
Usually the total mass fraction of alloying elements does not exceed 5%, belonging to low alloy steel; there are a few between 5% and 10%, belonging to the middle alloy steel. Most of the steel used for machine parts is a low SP content of high-quality steel, weathering steel plate manufacturers, the vast majority of good deoxidation of the sedentary steel.
In order to reduce the content of inclusions and gases in the steel, improve the purity and uniformity, rusted steel plate can be used in steel vacuum treatment, vacuum ingot casting, electroslag remelting, ladle refining, vacuum induction, vacuum self-consumption electrode and other melting methods.
