Detailed Product Description: | Rectangular pipe, rectangular steel pipe, rectangular steel pipe, thick-walled rectangular steel pipe, large diameter seamless rectangular steel, low alloy rectangular steel pipe, 500 * 300 * 16 rectangular steel, shipbuilding rectangular tube construction automobile frames with rectangular tubes, machinery manufacturing with low alloy rectangular steel pipe, rectangular steel, galvanized rectangular pipe, Q345B 20 # seamless rectangular steel rectangular tube, as the name implies, it is a kind of rectangular tube, the substance of a variety of materials can be formed tube of moments, it is medium in what for, with where most of the rectangular tube steel pipe for the majority, mostly rectangular tube structure, decorative rectangular tube construction rectangular tube rectangular pipe, rectangular pipe call the strip through the Process volume from the system. Generally strip After unpacking, flat, curled, welded to form a tube, rectangular tube by tube rolling and then cut to required lengths. Generally 50 per package. Seamless and weld rectangular tubes, seamless rectangular tube is extruded seamless tube made. 1. The rectangular tube performance index analysis of and - plastic plasticity refers to the metallic material under load, resulting in plastic deformation (permanent deformation) without disrupting the ability of. 2. The rectangular tube performance index analysis - Hardness Hardness is a measure of the hardness of the metal material pointer. Currently measured production the hardness method most commonly used is the indentation hardness method, it is pressed into the surface of a metallic material to be tested under a certain load with a certain geometry of the pressure head in, according to the extent of being pressed into the measured hardness values. Commonly used method Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and the Vickers hardness (HV). 3. The rectangular tube performance index analysis - strength, ductility, hardness are metal fatigue discussed earlier mechanical properties under static loading pointer. In fact, many of the machine parts are working in under cyclic loading, the part under such conditions will produce fatigue. 4. The rectangular tube performance index analysis - impact toughness at great speed action called impact load in the load on the mechanical, metal resistance to impact loads destruction called impact toughness. 5. The performance index of the rectangular tube analysis - strength strength refers to resist destruction (excess plastic deformation or fracture) the performance of the metal under the action of materials in the payload. Because the form of tension, compression, bending and shearing action of the load, so the strength is also divided into the tensile strength, compressive strength, bending strength, shear strength and the like. The various strength frequent contact, generally use more strength tensile strength as the most basic pointers. 1. In executable GB6728-2008 standard cold-formed hollow sections. 2. Executable JISG3466-88 Japanese general construction Rectangular pipe to adapt to a range of standards. |
