When stainless steel Angle steel is produced, the material is a general low carbon steel billet, and then made into stainless steel Angle steel, the hot rolling molding technology is used.
3. Stainless steel Angle steel has relatively high corrosion resistance, and has good corrosion resistance in the production process of pulp and paper making. And stainless steel is also resistant to the erosion of the ocean and aggressive industrial atmosphere.
4. Stainless steel Angle steel can be used for pulp and paper equipment heat exchangers, dyeing equipment, film washing equipment, pipelines, coastal area building external materials.
5. Precipitation-hardened stainless steel Angle steel is a steel that precipitates carbide in steel by heat treatment means, so as to achieve the purpose of improving strength.
6.Martensitic stainless steel Angle steel is a kind of steel that can adjust its properties by means of heat treatment, and its strength and hardness are high, which is of great use in process and mechanics. - What is the main use of hot rolled stainless steel channelWhat is the main use of hot rolled stainless steel channel?
(1) Hot-rolled stainless steel ordinary channel steel (GB707-88) is mainly used in building structures, vehicle manufacturing and other industrial structures, often used with I-steel.
(2) Hot rolled stainless steel light channel steel (YB164-63) Hot rolled light channel steel is a kind of steel with wide legs and thin walls, which has better economic effects than ordinary hot rolled channel steel. Its specifications range from 5-40#. In 1966, the metallurgical standard specified a specification range of 10-40#. Main applications: construction and steel frame structure.
The commonly used stainless steel channel materials in stainless steel production are :201, 202, 301, 304, 321, 316, 316l, and special materials can be customized. Stainless steel channel - Basic content Stainless steel channel is a kind of strip steel with a cross section of a groove. Stainless steel channel steel and I-steel, is divided into ordinary channel steel and light channel steel two. The model specification is also expressed in millimeters of waist height (h)× leg width (b)× waist thickness (d). For example, 120×53×5 channel steel waist height 120mm, round steel, add A, B, C on the right side of the model to distinguish. Generally, the model of stainless steel channel is expressed by the centimeter of the waist height, and the channel above is called 12# channel steel. Channel steel specifications range from 5 to 40#. Inclusion and marking requirements shall be implemented in accordance with GB2101-80.
Classification of stainless steel channels
1. Hot-rolled stainless steel ordinary channel steel (GB707-88) is mainly used in building structures, vehicle manufacturing and other industrial structures, often used with I-steel.
2. Hot rolled stainless steel light channel steel (YB164-63) Hot rolled light channel steel is a kind of steel with wide legs and thin walls, which has better economic effects than ordinary hot rolled chan - Types and specifications of stainless steel Angle steelStainless steel Angle steel is a bar shaped stainless steel plate with vertical angles on both sides. There are equal side stainless steel Angle and unequal side stainless steel Angle. The two sides of equilateral stainless steel Angle steel are the same width. The specification is indicated in millimeters of side width × side width × side thickness. Such as "∠25×25×3", it indicates that the side width is 30mm, the side thickness is 3mm equal side stainless steel Angle. It can also be indicated by the model number, which is the number of centimeters of the width of the side, such as ∠3#. The model does not indicate the specifications of different side thicknesses in the same model, so fill in the specifications of the side width and side thickness of the stainless steel Angle steel on the contract and other bills to prevent independent model indication. Reza equilateral stainless steel Angle steel specifications for 2#-20#.
Stainless steel Angle steel can be constructed according to the different structure must constitute a variety of different bearing prefabricated components, can also be used as a connection of the butt fastener.

- What is the general length of the weld for Angle steel and iron plate welding?The length of the welding seam of Angle steel and iron plate depends on the specific welding process, welding requirements, the thickness of the material and many other factors. In general, the weld length should be sufficient to ensure welding strength and quality without excessive waste of material and time. Under normal circumstances, the design of the weld length should meet the relevant welding standards and specifications, and need to be evaluated and designed according to the specific welding project.
- What are the precautions for using channel steel1, for the use of such products, it is necessary to check in advance whether there are defects in the product, such as cracks, bubbles and scarring, etc., which are very easy to lead to the phenomenon of fracture in the later use of the product, the risk is very high, and for the use of steel plates, there can be no stratification, otherwise it will seriously affect the smooth use of the product.
2, in use, it will be found that there are some thin layers of iron oxide and rust on the surface of the steel, as long as it does not affect the defects of the product, the existence of part is not relevant, mainly within a reasonable range. In addition, for the use of steel must pay attention to see whether it meets the relevant quality standards, because no matter what kind of occasion it is used in, if the quality is not up to standard, it will threaten human health.
3, in normal use, it will be found that there are some small defects on the surface of many steel, in fact, some small defects are allowed to exist, and these defects can be cleaned by grinding, but we must ensure the thickness of the steel, to smooth the surrounding treatment, no edges and corners, so as to ensure the normal use of the product. In addition, if the steel needs to be welded, it is also necessary to pay attention to the operation in accordance with relevant regulations. - Cause of difficulty in stainless steel cuttingStainless steel is the abbreviation of stainless steel, resistant to air, steam, water and other weak corrosive media or stainless steel; The steel that is resistant to chemical corrosive media is called acid-resistant steel. It has a good production process, but it is in production
Stainless steel is the abbreviation of stainless steel, resistant to air, steam, water and other weak corrosive media or stainless steel; The steel that is resistant to chemical corrosive media is called acid-resistant steel. It has a good production process, but in the process of production there will be cutting difficulties, the following is to introduce the reasons for cutting difficulties:
1, if the strength of the material itself is relatively large, then it will increase the two-way resistance in the cutting process, and it can also increase the cutting degree.
2, when we are in the process of processing and cutting, because of the large plastic deformation of the elongation of the product, it also brings a certain difficulty to the processing and production.
3, stainless steel is easy to expand, so it will produce a lot of heat in the cutting process, resulting in a bad reaction, resulting in expansion, but also increase the difficulty of cutting processing.
4, high cutting temperature will affect the product in the cutting process will produce high heat, but the material is relatively poor thermal conductivity, so the heat is all concentrated in the cutting area and the blade, it is not easy to heat.
5, the product is hard material cutting difficult, good plasticity, toughness, but when we are processing, cutting is not so easy to break, but it is easy to stick, resulting in cutting extrusion stainless steel surface, tool excessive wear.
Stainless steel processing in the production of the time will inevitably because of mistakes or other reasons leading to bad cutting technology, so in order to ensure the quality of its workpiece, so the staff before cutting to understand the pr
