Stainless steel plate refers to the steel plate resistant to weak medium corrosion such as atmosphere, steam and water, while acid resistant steel plate refers to the steel plate resistant to chemical etching medium corrosion such as acid, alkali and salt. Stainless steel plate has a history of more than one century since it came out in the early 20th century. It is a kind of alloy steel that is not easy to rust, but not absolutely rust free. Stainless steel plate is used in both construction and decoration. Its plasticity and toughness are much stronger than different steels, especially its corrosion resistance and oxidation resistance. Stainless steel has a wide range of uses. It is not only widely used in chemical, food, medicine, atomic energy and other industrial production, but also can be used in the manufacture of various equipment and machine parts, and can also be used as home decoration plate. In short, it can be seen everywhere. The charging method of stainless steel plate is calculated according to the weight. The unit price of different specifications of plate is different. The price of lower specification can be tens of yuan per kilogram, while the price of higher specification may be hundreds of yuan per kilogram. Therefore, the price of stainless steel pipe is mainly determined by rules. Do you want to know more about stainless steel plate? The following Xianji network small series to introduce stainless steel plate standard, stainless steel plate classification, stainless steel plate grade, stainless steel plate processing difficulties? The main points of stainless steel plate bending and its springback, stainless steel plate surface quality inspection, how to maintain stainless steel plate? Let's have a look!
Standard for stainless steel plate 1. Standard for hot rolled stainless steel plate: GB / t4237-2009 hot rolled stainless steel plate and strip, GB / t4238-2009 heat resistant steel plate and strip, JIS g4304-2005 hot rolled stainless steel plate, sheet and strip. 2. Executive standard for cold rolled stainless steel plate: GB / t3280-2009 cold rolled stainless steel plate and strip and GB / t4238-2009 heat resistant steel plate and strip.
Stainless steel plate classification according to different standards have different classification: 1, stainless steel plate according to thickness classification: can be divided into: thin plate (0.2mm-4mm), medium plate (4mm-20mm), thick plate (20mm-60mm), ultra thick plate (60-115mm). 2. According to the classification of production mode, stainless steel plate can be divided into: hot rolled steel plate (steel plate formed by heating furnace) and cold rolled steel plate (steel plate produced by cold rolling process). 3. Stainless steel can be divided into bridge steel plate, boiler steel plate, shipbuilding steel plate, armor steel plate, automobile steel plate, roof steel plate, structural steel plate, electrical steel plate (silicon steel sheet), spring steel plate and solar special plate (hailui special steel). 4. According to the classification of steel structure, stainless steel plate can be divided into: austenite type (200 series, 300 series stainless steel), austenite ferrite type (with the characteristics of austenite and ferrite stainless steel), ferrite type (409, 430, 434 series stainless steel), martensite type (403, 410, 414, 416,). 5. According to the classification of surface characteristics, stainless steel plate can be divided into: silver white matte (no need for surface gloss), bright as mirror (building materials, kitchen appliances), rough grinding / intermediate grinding / fine grinding / very fine grinding (building materials, kitchen appliances), hairline grinding (building, building materials), close to mirror grinding (art, decoration), mirror grinding Grinding (mirror, decorative).
Grade of stainless steel plate
First, let's start with the big ones. Do you know what kind of stainless steel is used in vehicles, trains and aviation products? It's the stainless steel product represented by the humble name 301. Its characteristic is that the tensile strength increases during cold working, and there is no magnetism, but after processing, there is magnetism.
Second, and we are closely related to tableware, cabinets, bathtubs and other products of 304 steel, the name is very familiar with it, generally we go to the building materials into the purchase of decoration products, the shopping guide will say that we are 304 stainless steel. This steel has stable properties, excellent heat resistance and low temperature resistance. It can handle from - 196 to 800 . But it's too stable for bending.
Third, 304cu is used for kettle, door handle and vegetable washing basin. This kind of steel has excellent wire drawing resistance and crack resistance, meeting the weakness that 304 steel can't bend greatly. Fourth, 436l steel is used for washing machines, automobile exhaust pipes and stainless steel pots. This type of steel has good heat resistance, excellent processing and welding performance, so it is suitable for these products.
What are the difficulties in stainless steel plate processing? Stainless steel plate has smooth surface, high plasticity, toughness and mechanical strength. We often see the shadow of stainless steel in our life and work. However, the following difficulties are encountered in the processing, which affect the processing quality of stainless steel plate 1. High cutting force and high cutting temperature: stainless steel plate has high strength, large tangential stress and large plastic deformation during cutting, resulting in high cutting force and poor thermal conductivity, resulting in high cutting temperature, and the high temperature is often concentrated in the narrow area near the cutting edge, thus speeding up the tool wear; 2. Easy to stick: there are characteristics of strong and tough chips and high cutting temperature during machining. When the strong and tough chips flow through the rake face, there will be adhesion, fusion welding and other phenomena, which will affect the surface roughness of machined parts; 3. Accelerated tool wear: generally containing high melting point elements, high plasticity and high cutting temperature, the tool wear is accelerated, and tool grinding and changing are frequent, which affects the production efficiency and improves the tool cost.
The main points of stainless steel plate bending and its springback are as follows: 1. Due to the high yield point, high hardness and significant cold work hardening effect of stainless steel plate, the characteristics of stainless steel plate bending are as follows: 1; 2. Compared with carbon steel, stainless steel sheet has a strong rebound tendency during bending; 3. Due to the low elongation, the bending angle R of stainless steel sheet is larger than that of carbon steel, otherwise cracks may appear;
