The material process performance of Shenyang American Standard Seamless Coil is common for forgeability, castability, weldability and machinability. These properties are very important in the processing and application of materials, which will closely affect the quality of the finished products. So understanding of these capabilities needs to be in place.
First of all, look at the forgeability, which refers to a property in which the stainless steel coil material can change shape without forming cracks during press working. It can be processed by hammer forging, rolling, drawing, extrusion, etc. in hot or cold state. Among them, the forgeability depends mainly on the chemical composition of the stainless steel coil material.
Followed by castability, this means that the stainless steel coil material can be cast to obtain the performance of a qualified casting. Castability mainly includes fluidity, shrinkage and segregation. Fluidity refers to the performance of liquid metal filling the mold; shrinkage refers to the degree of volume shrinkage when the casting solidifies; segregation refers to the chemical composition of the stainless steel coil during the cooling and solidification process due to the difference in crystallization. And organizational heterogeneity.

The weldability is also called weldability, and refers specifically to the adaptability of the stainless steel coil material to the welding process. Mainly refers to the difficulty of obtaining high-quality welded joints of stainless steel coils under certain welding process conditions. It includes two aspects: one is
The theoretical weight of Shenyang American Standard Seamless Pipe is based on the nominal size and density (also called specific gravity) of stainless steel. The calculated weight can be referred to as the theoretical weight. This has a direct relationship with the length, cross-sectional area and dimensional tolerance of stainless steel. Because of the allowable deviation of the stainless steel sheet during the manufacturing process, the theoretical weight calculated using the formula has a certain discrepancy with the actual weight, so it can only be used as a reference for estimation.
The actual weight of the stainless steel sheet refers to the weight of the stainless steel sheet obtained by actual weighing (overweight), so it is called the actual weight. The actual weight is more accurate than the theoretical weight.
There are mainly the following methods for calculating the weight of Shenyang American Standard Seamless Pipe .
One is the gross weight, which is the symmetry of the net weight and the total weight of the stainless steel itself and the packaging material. Transportation companies usually calculate gross freight by gross weight. However, stainless steel plates are usually calculated on the basis of net weight in the purchase and sale.
The second is net weight, which is the symmetry of gross weight. The weight of the stainless steel sheet minus the weight of the packaging material, which is the actual weight, can be called the net weight. In the purchase and sale of stainless steel plates, it is usually calculated according to the net weight.
The third is the tare weight, which is the weight of the packaging material of stainless steel, which can be called tare weight.
Regarding the weight tons, it is the weight unit used to calculate the freight rate based on the gross weight of the stainless steel sheet. Its legal unit of measurement is tons (1000kg), as well as long tons (inch weight unit 1016.16kg), short tons (US system weight unit 907.18kg).
The fifth is the billable weight, also known as billing tons or freight tons, which is usually the weight of the stainless steel sheet referenced by the transportation department when collecting freight. Different modes of transportation have different calculation standards and methods. For example, railway full-vehicle transportation is usually based on the truck marked load used as the billable weight.
The bonding performance, that is, the sensitivity of the welding defects under certain welding process conditions; the second is the use performance, that is, the suitability of the welded joint to the use requirements under certain welding process conditions.
The latter part of Shenyang stainless steel plate is machinability, or is called machinability and machinability. It refers to the ease with which a stainless steel coil material is cut into a qualified workpiece. The 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 degree of work hardening of stainless steel coil materials. It is usually a rough judgment of the hardness and toughness of the machinability. Generally speaking, the higher the hardness of the stainless steel coil material, the more difficult it is to cut, and if the hardness is not high, but the toughness is large, it is also difficult to cut.
