eFunda: Glossary: Materials: Alloys: Alloy Steel: ASTM a202 gr a steel manufacture Rolling
ASTM A202 Grade B is categorized as Alloy Steel. It is composed of (in weight percentage) 0.25% Carbon (C), 1.05-1.40% Manganese (Mn), 0.035% Phosphorus (P), 0.04% Sulfur (S), 0.60-0.90% Silicon (Si), 0.35-0.60% Chromium (Cr), and the base metal Iron (Fe). Another common designation of ASTM A202 Grade B alloy steel is UNS K12542.What is the temperature at which steel is rolled?The process always starts with hot rolling. Hot rolling refers to the process of rolling steel at a temperature typically above 900° C, greater than its recrystallisation temperature. This allows steel sheets to be made in larger, thicker sizes, ideal for the manufacture of railway rails, large beams, or girders.See all results for this questionWhat happens to the thickness of steel during Rolling?The steel material gets squeezed between the pair of rolls, as a result of which the thickness gets reduced and the length gets increased. Rolling is classified according to the temperature of the steel rolled. If the temperature of the steel is above its recrystallization temperature, then the process is termed as hot rolling.See all results for this question
What are the two types of rolling process?
There are two main types of rolling process: Flat rolling the finished product is a sheet Profile rolling the finished product is a bar or rod. The process always starts with hot rolling. Hot rolling refers to the process of rolling steel at a temperature typically above 900° C, greater than its recrystallisation temperature.See all results for this questionTop US Steel Companies and Steel Manufacturers in WorldWelcome to the Thomas guide to the top US steel companies and global steel manufacturers. Steel is a versatile metal that is used in construction and as a core material for the manufacturing of a large range of products for commercial or consumer use.

Sheet Metal is a metal being formed by a manufacturing process into thin, flat pieces. The sheet metal rolling process consists of passing metal stock through one or more pairs of rolls to reduce the thickness and to make the a202 gr a steel manufacture Rolling
Scale formation and its removal in Hot Rolling process
During hot rolling of steel, its surface is exposed to air which leads to oxidation, resulting in scale formation. The scale formation is affected by the temperature, steel grade, surrounding atmosphere and the exposure time. There are two kinds of scales relevant in rolling mills sticky and dry scales.Normalizing rolling - voestalpineEffects of normalizing rolling. The grain size is minimized through low forming temperatures because grain growth is greatly reduced during recrystallization. The material grain is refined, and the microstructure is homogenized. The material is subsequently cooled. The steel properties are similar to those of normalized-annealed plates.Nickel plates - voestalpineThe revision of API Standard 620 in 2018 has made it possible to use ASTM steel grades A 645 Gr A and Gr B for the construction of ethylene, LPG or LNG tanks. Our state-of-the-art production facilities make it possible for us to manufacture both steel grades A 645 Gr A and Gr B as well as conventional 5% and 9% nickel steels. Learn more

See allSee all imagesHow does metal rolling change the grain structure?Rolling a metal above its recrystallization temperature breaks apart the old grain structure and reforms a new one. Grain boundaries are destroyed and new tougher ones are formed, along with a more uniform grain structure. Metal rolling pushes material, closing up vacancies and cavities within the metal.See all results for this questionDevelopment of a new three-stage cold rolling a202 gr a steel manufacture RollingThe static recrystallization kinetics and the recrystallized grain size of 3% Si steel after hot rolling at temperatures of 900 to 1100 degrees C to equivalent strains of 0.25 to 1.24 applied in a a202 gr a steel manufacture Rolling
