2019-08-28Stainless steel maintenance method
With the development of economy, the use of stainless steel has become more widespread. People are closely related to stainless steel in daily life. However, many people don't know much about the performance of stainless steel, and even a few know about the maintenance of stainless steel. Many people think that stainless steel will never rust. In fact, stainless steel has good corrosion resistance because of the formation of a pure film on the surface. In nature, it exists in the form of a more stable oxide. In other words, although the degree of oxidation of stainless steel is different depending on the conditions of use, it is eventually oxidized. This phenomenon is usually called corrosion. Electrochemical reactions occur on all metal surfaces exposed to corrosive environments
2019-08-27What to do if the surface of stainless steel is damaged?
What to do if the surface of stainless steel is damaged? For most people, this should be a big problem! So today, the editor will lead you to solve this headache. You will not be afraid of stainless steel damage in the future! First of all, let’s take a look at what causes damage to the surface of stainless steel; there are many reasons for damage to the surface of stainless steel, including dust, floating iron powder or embedded iron, scratches, rust spots, rough grinding and machining, welding arc marks, Welding spatter, flux, welding defects, oil and grease, residual adhesive paint, chalk and marking pen prints, etc. The solution to each cause is different! powder
2019-08-25What are the precautions for installing stainless steel anti-theft windows
What are the precautions for installing stainless steel anti-theft windows 1. The processing table of stainless steel anti-theft windows should be covered with rubber sheets and other soft cushions to avoid damage to the stainless steel surface. Whether it is stainless steel window raw materials or processed parts during transportation, loading and unloading, special hoisting should be used For transportation tools, avoid contact between stainless steel and other sharp carbon steels, causing bumps and scratches on the surface. 2. When stainless steel parts are blanked, the plates should be cut or plasma cut; pipes and other profiles should be cut by plasma or sawing. Lay rubber cushions when cutting to avoid damaging the surface; after plasma cutting, clean the cutting slag in time; when sawing
2019-08-24What is the difference between steel and stainless steel?
For the difference between ordinary steel and stainless steel. Ordinary steel is carbon steel, that is, iron-carbon alloy. According to the level of carbon content, it is divided into low carbon steel (wrought iron), medium carbon steel and cast iron. Generally, those with a carbon content of less than 0.2% are called low-carbon steel, commonly known as wrought iron or pure iron; those with a content of 0.2-1.7% are called steel; those with a content of more than 1.7% are called pig iron. The steel containing more than 12.5% of chromium in the steel and having high resistance to corrosion by external media (acid, alkali salt) is called stainless steel. According to the structure of the steel, stainless steel can be divided into martensite, ferrite, austenite, ferrite-austenite, precipitation hardening type
2019-08-22Stainless steel experience | easy way to identify 304 and 201 stainless steel
304 stainless steel is one of the most widely used mainstream steel grades at present, because of its obvious corrosion resistance, and 201 stainless steel because of its relatively poor corrosion resistance, resulting in different widely used areas and different prices. The price of 201 is lower than that of 304. In reality, some unscrupulous manufacturers often pretend to be 304 to promote and sell externally to obtain high profits. In order to prevent you from being deceived by unscrupulous manufacturers, the editor summarizes three simple and easy-to-understand methods to identify 304 and 201 stainless steel based on the experience of professionals: 1. Look with the naked eye and touch with your hands. 2
2019-08-21What are the surface treatment processes of stainless steel?
The stainless steel surface treatment processes that we commonly see in the market include wire drawing, mirror surface, sandblasting, titanium plating, etching, anti-fingerprints, etc. The surface treatment process of stainless steel screens is created by different colors and styles. What do you want to achieve? Use different colors for the effect

Six steps to the maintenance of stainless steel stairs: 1. The first part should always check the connecting parts of the stainless steel stairs to prevent loosening or being eaten by insects. Because when stainless steel stairs are installed, even if they are closely connected by the stair engineer, with the continuous changes of temperature and humidity, all components are undergoing subtle physical changes. 2 Part 2 If the wooden treads of the stainless steel stairs are accidentally soaked in water, they should be wiped dry as soon as possible after being found, and allowed to dry naturally. It is strictly forbidden to use an electric heater to dry. 3Part Three Exposure to strong sunlight for a long time or the temperature in the room
2019-08-17Dongheng Honggang|Do you have 7 cleaning tips for color stainless steel doors?
Color stainless steel door cleaning method! The first case: If only the surface of the door has dirt attached, then wipe it with detergent. But it should be noted that the material of the stainless steel door is mirror or brushed. If the mirror is mirrored, special attention should be paid to the cleaning tools. The rag must be clean and dust-free. In addition, there are special cleaning agents for stainless steel cleaning, called stainless steel cleaning agents or stainless steel brighteners, and special care agents, including stainless steel oil, can remove stains and restore the brightness of stainless steel. The second case: If you want to remove the trademark or film tape traces on the door, you can wipe it with warm water and then use alcohol
2019-08-14Correctly understand no fingerprints! What is no fingerprint? Why there are fingerprints on no fingerprints!
Features: The domestic first non-fingerprint stainless steel matte plate technology processing technology, the process of non-fingerprint stainless steel plate, completely change the cold and dull stainless steel flaws, has the advantages of novelty, environmental protection, durability, strong three-dimensionality, hygienic and beautiful, effectively becoming The visual effect loved by consumers. The advantages of no fingerprints are visual aesthetics, high quality, easy to clean, maintenance-free, anti-strike, anti-pressure, anti-scratch, and no fingerprints.

The main purpose is to prevent people from touching these boards.
2019-08-12Introduction to common stainless steel types and their characteristics
The types of stainless steel used in the project are mainly austenitic stainless steel, martensitic stainless steel and ferritic stainless steel. These three kinds of steel have their own characteristics. The following editor will summarize and introduce as follows: Austenitic stainless steel includes iron-chromium-manganese Types, iron-chromium-manganese-nickel alloys, and special-purpose ones include nitrogen, copper, silicon and other elements. Austenitic stainless steel is the most commonly used type. It belongs to the 200 and 300 series in the old AISI system. It is usually not magnetic. Cold working can make it significantly hardened, with excellent formability and weldability. Compared with carbon steel, it has low thermal conductivity and large thermal expansion coefficient. The main grades are S3040
