Cold rolled steel sheet mechanical properties of aluminum

Dec 28, 2015 · Full-sized ingots containing 0.004–0.019% nitrogen were made jrom a 0.025% aluminum-killed steel heat and processed to cold-rolled sheet under produc This paper compares the mechanical properties obtained from the controlled nitrogen additions with those obtained for aluminum-killed steels that absorbed nitrogen during box annealing.

But the oxidation layer also makes hot-rolled steel has a rough surface and large size volatile, so the steel require a bright clean surface, precise size and good mechanical properties need to be produced into semi-finished by hot rolling or finished products as raw materials to produce by cold rolling. Alibaba.com offers 1,512 hot rolled steel material properties products. About 70% of these are steel pipes, 13% are steel sheets, and 1% are other metals & metal products. A wide variety of hot rolled steel material properties options are available to you, such as iso, api, and bsi.

Cold Rolled Steel is steel which has been rolled at room temperature, below its recrystallization temperature. This increases its strength and hardness and decreases its ductility. In addition to improvement of mechanical properties, cold rolling results in more control over the shape and dimensions of the finished product.

Cold rolled steel is produced by further processing hot rolled steel through cold reduction mills (at room temperature) followed by annealing and/or temper rolling to produce steel with closer dimensional tolerances and a wider range of surface finishes.

Flat-rolled steel products consist of two kinds, namely, hot rolled sheets and cold rolled sheets. They are manufactured differently, each having its particular application. Hot Rolled Steel. Hot rolled steel is turned into a coil of steel while the temperature is above 1700 degrees Fahrenheit. This process makes the material more malleable ... Nov 13, 2019 · Cold rolling is the most common method of work hardening. This involves the metal being passed through pairs of rollers to reduce its thickness or to make the thickness uniform. As it moves through the rollers and is compressed, the metal grains are deformed. Examples of cold-rolled products include steel sheets, strips, bars, and rods. It is suitable for measuring soft metals such as nonferrous metals, annealing, and normalizing steel. HRC: The hardness was obtained by applying 588N pressure at the diamond cone with 120° vertex angle for testing samples. It is suitable for measuring hard metal such as tempered steel and hardened steel. Aluminized steel is steel that has been hot-dip coated both sides with aluminum–silicon alloy (5%-11%). This process assures a tight metallurgical bond between the steel sheet and its aluminum coating, producing a material with a unique combination of properties possessed neither by steel nor by aluminum alone. Aluminized steel shows a better behavior against corrosion and keeps the properties of the base material steel for temperature lower than 800 °C(1,472 F). From plate to sheet and aluminum foil. The production of sheet or foil usually starts out the same way as plate but the slab is further rolled through a continuous mill to reduce thickness and wound into a coil at the end of the line. These coils are subsequently cold rolled, from one to several passes at cold rolling mills.
