Stainless Steel Bar Steel cold profile
1, stainless steel bar Product Description
Stainless steel bar is a hollow square section of light-weight thin-walled steel pipe, also known as steel cold-formed profiles. It is Q235 hot-rolled or cold-rolled strip or coil as the base metal by the cold twist processing and then made by high-frequency welding of the square cross-sectional shape of the shape of the steel. Hot-rolled thick-walled stainless steel square pipe in addition to wall thickness thickening of the situation, the corner of the scale and edge flatness to reach even more than the resistance of cold-formed stainless steel square tube level. Comprehensive mechanical function, welding, cold, hot processing and corrosion resistance are good, with outstanding low temperature resistance.
2, stainless steel bar useful
Stainless steel rods are used to build, machinery manufacturing, steel and other projects, shipbuilding, solar power generation scaffolds, steel works, power engineering, power plants, agricultural and chemical machinery, glass curtain wall, car chassis, airport, boiler, Housing construction, pressure vessels, oil storage tanks, bridges, power station equipment, lifting transport machinery and other high load welding structures and so on.
Stainless steel square tube function
Plasticity refers to the metal material in the load effect, the occurrence of plastic deformation (permanent deformation) without damage to the ability.
Hardness is a measure of the degree of hard and soft metal materials. The most commonly used method of measuring hardness in production is the press hardness method, which is used to press the surface of the metal material to be tested under a constant load with a constant number of indentations. The hardness value is measured according to the degree of penetration.
Commonly used methods are Brinell hardness (HB), Rockwell hardness (HRA, HRB, HRC) and Vickers hardness (HV) and other methods.
The strength, plasticity, and hardness discussed above are the mechanical functions of the metal under static load. In fact, many machine parts are operating under cyclic loading, under which the parts will be exhausted.
The load on the machine with great speed is called the impact load, and the metal can resist the damage under the impact load.
Strength refers to the metal material in the static load under the effect of damage (excessive plastic deformation or cracking) function. As the effect of the load method of stretching, compression, twists and turns, cutting, etc., so the strength is also divided into tensile strength, compressive strength, bending strength, shear strength. There is often a certain degree of strength between the contact, the general use of more tensile strength as the most basic strength indicators. Stainless steel bar shopping malls prices steadily up. According to Lange stainless steel bar cloud business channel monitoring data show: the country is the key cities 108 * 4.5mm seamless average price of 2955 yuan, compared with yesterday's price rose 2 yuan. The rest of the vast number of shopping malls are still selected to look around the main operation, mainly due to the upstream price hike too fast, and the current domestic demand is poor, high temperature and rain on the mall shipping more severe, , So that the atmosphere of shopping malls look dense, stainless steel bar market again followed by the market is likely to follow the market. It is estimated that the domestic short-term domestic stainless steel bar shopping malls prices will continue to run steadily. Costs, Tangshan, Changli Pu carbon billet down 90 yuan, today afternoon to reproduce the rebound traces, a slight increase of 10 yuan; tube factory continued to adhere to the rhythm, the weekend Linyi tube factory price of 50 yuan, is 108 * 4.5 mm factory price of 2650 yuan, Yantai Yuan Hua raised the price of 30 yuan, is 219 * 6mm vehicle price of 2680 yuan. Shopping malls, the domestic seamless steel mall not yet show a large area with the phenomenon, only part of the regional shopping prices rose slightly, Beijing, Shanghai, Linyi, Tai'an, Yantai, Cangzhou, Changsha, Lecong and other places shopping prices rose 20-50 yuan Ranging from
