Processing Performance of Thick-walled Carbon Steel Pipe

Date:2018-04-04    keywords:thick-walled carbon steel pipe
Thick-walled carbon steel pipe processing performance is as follows:
1: Thick-walled carbon steel pipe castability (castability): Refers to the ability of a metal material to obtain acceptable castings by casting. Castability mainly includes fluidity, shrinkage and segregation. Liquidity refers to the ability of liquid metal to fill molds. Shrinkage refers to the degree of volume shrinkage when a casting solidifies. Segregation refers to the inhomogeneity of chemical composition and organization within a metal due to successive differences in the crystal during cooling and solidification. .

2: Thick-walled carbon steel pipe forgeability: Refers to the ability of a metal material to change shape without cracking during pressure processing. It includes hammer forging, rolling, drawing, extrusion, etc. in hot or cold state. The malleability is mainly related to the chemical composition of the metal material.

3: Thick-walled carbon steel pipe Machinability (machinability, machinability): Refers to the degree of difficulty for a metal material to be a qualified part after being cut by a tool. Machinability is usually measured by the surface roughness of the workpiece after machining, the allowable cutting speed and the degree of wear of the tool. It is related to many factors such as chemical composition, mechanical properties, thermal conductivity, and work hardening degree of metal materials. It is generally judged by hardness and toughness as a measure of the machinability. In general, the higher the hardness of metal materials, the harder it is to cut. Although the hardness is not high, the toughness is large and the cutting is difficult. 

4: Weldability (weldability): Refers to the adaptability of metal materials to welding processes. Mainly refers to the degree of difficulty in obtaining high quality welded joints under certain welding conditions. It includes two aspects: First, the combination of properties, that is, in a certain welding process conditions, a certain metal to form the sensitivity of welding defects, the second is the use of performance, that is, in a certain welding process conditions, a certain degree of metal welding Applicability of joints to use requirements.
