1. What is carbon steel plate?
It mainly refers to the steel whose carbon content is less than 2.11% and does not contain alloy elements intentionally added. Sometimes called plain carbon steel or carbon steel. Carbon steel is also called carbon steel, which refers to iron carbon alloy with carbon content Wc less than 2.11%. Carbon steel generally contains a small amount of silicon, manganese, sulfur and phosphorus in addition to carbon
2. What is the classification of carbon steel?
(1) According to the use, it can be divided into three categories: structure, tool and free cutting structural steel.
(2) According to the way of smelting, it can be divided into open hearth steel, converter steel and electric furnace steel.
(3) According to the deoxidation route, it can be divided into rimmed steel, killed steel, semi killed steel and special killed steel.
(4)According to the carbon content, it can be divided into low carbon, medium carbon and high carbon.
3. What are the specifications of carbon steel plate?
The specification of carbon steel plate is mainly determined by its shape. There are many specifications of flat steel, medium and thick plates and open and flat coils. Here are some common specifications of carbon steel plate. Generally speaking, in the area with a thickness of 3-200m, carbon steel plate mainly includes 20 # steel plate, 10 # steel plate, and 35 # steel plate. Most of these steel plates use heat rail technology. However, the hot medium thick carbon steel plates mainly include Q235A, B, C, D, etc. The thickness is not low. The carbon steel plate products of cold emulsion technology are mainly round steel, generally including Q195 round steel, A3 round steel, Q235 round steel, K40 round steel, T8 round steel, T10 round steel, Q345A round steel, Q345B round steel, etc.
4. Common steel use classification symbol?
Carbon structural steel for boiler: Q245R
Carbon steel for welding gas cylinders: HP235, HP265, HP295
Carbon structural steel for bridge: Q235q
Steel for boiler and pressure vessel: 20R, 20g, 20HR (nuclear grade)
Carbon steel for pipeline: L245, L175, L290
Steel for rail: U71, U71Mn
Steel for automobile manufacturing: 370L, 420L
5. What are the advantages and disadvantages of carbon steel plate?
Its advantages are:
(1) After heat treatment, the hardness and wear resistance can be improved.
(2) The hardness is appropriate and the machinability is good during annealing.
(3) Its raw materials are very common, so it is easy to find, so the production cost is not high.
Its disadvantages are:
(1) Its thermal hardness is not good. When it is used as a tool material, its hardness and wear resistance will deteriorate when the temperature exceeds 200 degrees.
(2) His diameter is usually 15 to 18 mm when the water is poor in consistency and permeability, while the diameter and thickness are usually 6 mm at different times, so it is easy to have deformation or cracking problems
6.Which is better, ordinary steel plate or carbon steel plate?
Carbon steel plate is better than steel plate. Carbon steel is usually referred to as carbon steel. The impurities in its materials are less than those in iron, and it is more widely used. The steel is made from molten iron. During smelting, the harmful elements in molten iron are removed, the components are more pure, and alloy elements are added, so its comprehensive performance is good. However, the brittleness of iron is relatively large and its application scope is less. The advantages of carbon steel plate are: 1. After heat treatment, the hardness and wear resistance can be improved. 2. The hardness is appropriate and the machinability is good during annealing. 3. Its raw materials are very common, so it is easy to find, so the production cost is not high.
7.Use of carbon steel:
Q195 is used to manufacture parts, iron wires, iron rings, sizing blocks, cotter pins, pull rods, stamping parts and welding parts with small load.
Q215A is used to manufacture pull rod, ferrule, washer, carburized ring, carburized parts and weldments.
Grade Q235AA and B are used to manufacture metal structural parts, carburized parts or carbonitrided parts with low requirements for central strength, pull rods, connecting rods, hooks, couplers, bolts, nuts, sleeves, shafts and connectors; C. Class D is used to manufacture important welded structural members.
Q255A is used to manufacture parts with low strength requirements, such as rotating shafts, mandrels, hooks, pull rods, rocker bars, wedges, etc. This negative weldability is acceptable.
Q275 is used to manufacture shafts, sprockets, gears, hooks and other parts with high strength requirements.
