The total heat transfer coefficient of a metal depends on other factors besides the thermal conductivity of the metal. In most cases, the heat dissipation coefficient of the film, the rust skin and the surface condition of the metal. Because stainless steel keeps the surface clean, it conducts hea

1) Small and medium-sized steel bars, wire rods, steel bars, medium-diameter steel pipes, steel wires and wire ropes, etc., can be stored in a well-ventilated material shed, but must be placed on top and under the pad.2) Some small steels, thin steel plates, steel strips, silicon steel sheets, small

1. CleaningUse solvents and emulsions to clean the surface of steel to remove oil, grease, dust, smoothing agent and similar organic matter, but it cannot remove the rust, oxide scale, welding flux, etc. on the surface of the steel, so it is only used as an auxiliary trick in anti-corrosion producti
