Galvanized pipe, high amount of zinc pipe, 560 g galvanized square tube

Hardness is a measure of the hardness of the pipe material the hardness of the metal pointer. Production method for measuring the hardness currently most common method is the indentation hardness, it is certain geometry indenter under a certain load is pressed into the surface of a metallic material to be tested, to determine the hardness value according to the degree of being pushed. Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV) and other methods commonly used method. In front of square tube fatigue strength discussed, ductility, hardness is metal under static load mechanical performance indicators. In fact, many machine parts are working under cyclic loading, part under such conditions will produce fatigue. Toughness square tubes with great speed on the load acting on the parts called impact load capacity of metal to resist destruction under impact loading is called toughness. RHS storage warehouse to keep clean, reinforcing material conservation (1) material before storage to guard against rain or mixed with impurities, which has been exposed to rain or soiled materials to their nature in different ways wipe, such as high hardness available wire brush, low hardness with a cloth, cotton and other things; (2) the storage of materials should always check if rust, corrosion layer should be removed; (3) general steel surface cleared after the net, do not smear oil, but high-quality steel, alloy steel sheet, thin-walled pipe, steel pipe, etc., required after blasting its inner and outer surfaces coated with anti-rust oil before storage; (4) not long after the more serious pipe corrosion, rust custody, should be used as soon as possible. [1000-pipe to introduce you to the star product - hot galvanized square tube] product performance galvanized square tubes has good strength, toughness, ductility and welding process performance and have good ductility, the alloy layer and steel attached to a solid base, so hot galvanized square tube can be cold punching, rolling, drawing, bending and other forming without damaging the coating; for general machining such as drilling, cutting, welding, cold and other technology. Galvanized after surface bright and beautiful, it can be directly used for engineering on demand.
