What is alloy steel
Alloy steel is a kind of iron carbon alloy with one or more alloying elements added on the basis of ordinary carbon steel. Can obtain high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistance, non-magnetic and other special properties, widely used in Bridges, boilers, ships, armor, cars, roofing, springs and so on. Due to the high content of Cr, C and other alloying elements in alloy plate, the hardening tendency of steel is obvious and the weldability is poor. The steel plate is flat, rectangular and can be rolled directly or cut from a wide strip of steel.
Alloy plate classification
classification | Alloy plate |
| thickness | thin steel plate < 4mm, width 500 ~ 1500mm. thick steel plate 4 ~ 60mm, width 600 ~ 3000mm . extra thick steel plate 60 ~ 115mm |
| rolling | hot rolled and cold rolled |
| application | bridge steel plate, boiler steel plate, shipbuilding steel plate, armored steel plate, automobile steel plate, roof steel plate, structural steel plate, electrical steel plate, spring steel plate and others |
structural (its brand can be expressed by yield point or carbon content or alloy elements) | steel plate r for pressure vessel, steel plate HP for welded gas cylinder, steel plate g for boiler, steel plate Q for bridge and steel plate l for automobile girder |
| alloy steel | According to the content of alloying elements, it is divided into low alloy steel (less than 5%), medium alloy steel (5% - 10%) and high alloy steel (more than 10%). |
| According to the main alloy elements contained, it is divided into chromium steel (Cr-Fe-C), chromium nickel steel (cr-ni-fe-c), manganese steel (Mn-Fe-C) and silicon manganese steel (si-mn-fe-c) | |
| According to the normalized or as cast structure of small samples, they are divided into pearlitic steel, martensitic steel, ferritic steel, austenitic steel and ledeburite steel, | |
| It is classified into alloy structural steel, alloy tool steel and special performance steel |
Product introduction
Product | introduction |
| ASTM1015 alloy plate | It has high thermal strength and oxidation resistance at high temperature, and has a certain hydrogen corrosion resistance. |
| ASTM1035 alloy plate | It has high wear resistance and good impact performance. It can cut, bend and weld. It is time-saving and convenient in the process of maintenance. It is widely used in metallurgy, coal, cement, electric power, glass, mining, building materials, brick and tile and other industries Compared with other materials, it has high cost performance. |
| ASTM5140 alloy plate | After quenching and tempering, it is used to manufacture mechanical parts with medium load and medium speed, or parts with high load and different impact speed after quenching and medium temperature tempering, as well as various transmission parts with carbonitriding treatment. |
| ASTMA182F92alloy steel plate | After nitriding, the quality inspection of nitriding layer includes nitriding layer depth, surface hardness, nitriding layer structure, brittleness and deformation, which has an important impact on the service conditions and service life of alloy steel plate. |
| ASTM A6 alloy steel plate | increase tempering brittleness. Like carbon steel, alloy steel also produces tempering brittleness, which is more obvious. |
| ASTM4140 alloy steel plate | High strength and hardenability, good toughness, small deformation during quenching, high creep strength and lasting strength at high temperature. It is used to manufacture forgings with higher strength and larger quenched and tempered section than 35CrMo steel, or molds for drill pipe joints, fishing tools and bending machines in oil deep wells below 2000m. |

Steel plate material description
Not all steel plate materials are the same, the material is not the same, the place where the steel plate is used is not the same.
Alloy plate weight calculation formula: length × width × thickness ×0.00785=kg/m
