The company is committed to becoming a steel service provider that provides customers with a full range of steel demand solutions! Now we will introduce you about the eight process properties of steel materials.

1. Castability

The ability of a metal material to obtain a qualified casting by a casting method is called castability. Castability includes fluidity, shrinkage and segregation tendency. Flowability refers to the ability of liquid metal to fill the mold. The better the fluidity, the easier it is to cast thin and delicate castings. Shrinkage refers to the degree of volume shrinkage when the casting solidifies. The smaller the shrinkage, the smaller the deformation when the casting solidifies. Segregation refers to the uneven chemical composition, the more severe the segregation, the more uneven the performance of various parts of the casting, and the lower the reliability of the casting.

2. Machinability

The machinability of a metal material refers to the ability of the metal to undergo cutting, and it also refers to the ease with which the metal can be processed into a desired workpiece. Roughness, cutting speed, and tool wear of the work surface after cutting can usually be used to evaluate the machinability of the metal.

3. Weldability

Weldability refers to the performance of welded joints where the metal can obtain the expected quality requirements through common welding methods under specific structural and process conditions. Weldability is generally judged by the sensitivity of cracks generated during welding and changes in the mechanical properties of the weld zone.

4. Forgeability

Forgeability is the ability of the material to change its shape without cracking when subjected to processing techniques such as hammer forging, rolling, drawing, and extrusion. It is actually a manifestation of metal plasticity. The higher the plasticity of a metal material, the smaller the resistance to deformation, and the better the forgeability. Forgeability is mainly determined by the chemical composition, microstructure, deformation temperature, deformation speed and stress state of the metal.

5. Stamping

Stampability refers to the performance of metal without deformation such as cracks after stamping. Many metal products are manufactured through stamping processes, such as car shells, enamel products, and daily necessities such as pots, basins, pots, and pots. In order to ensure the quality of the product and the smooth progress of the process, the metal plates and belts used for stamping must have qualified stamping properties.

6. Forging

Upset property refers to the ability of a metal material to withstand upset deformation such as riveting and hoeing. The upset property of metal is measured by upset test.

7. Cold bendability

The ability of metal materials to withstand bending without breaking at room temperature is called cold bending. The greater the degree of bending that can be sustained before cracks occur, the better the cold bending performance of the material.

8. Heat treatment processability

Heat treatment refers to a process operation in which the metal or alloy is in the solid state range through certain heating, heat preservation and cooling methods to change the internal structure of the metal or alloy to obtain the required properties. Heat treatment process refers to the ability of a metal to change its structure and properties after heat treatment, including hardenability, temper brittleness, and so on.
