A brief description of the development of stainless steel factory
Stainless steel factory is the floorboard of stainless steel plate and acid resistant steel. Stainless steel plate is refers to the resistance of air, steam and water and the weak Stainless steel factory medium of stainless steel factory, and acid resistant steel is resistant to acid, alkali, salt and other chemical etching medium corrosion of steel plate. Stainless steel factory since the beginning of this century came, now has more than 90 years of. Stainless steel factory's invention was a great achievement in the history of metallurgy in the world, the development of stainless steel plate and laid an important material and technological foundation for the development of modern industry and the progress of science and technology. Stainless steel plate for many, the performance of different, it is in the development process, gradually formed a few categories. According to the organizational structure is divided into martensitic stainless steel plate (including precipitation hardening stainless steel plate), ferritic stainless steel sheet metal steel plate, stainless steel factory and ferrite and ferrite dual phase stainless steel factory four class? According to some characteristic elements of main chemical components or steel plate in the classification, divided into chromium stainless steel plate, chromium nickel stainless steel plate, nickel chromium molybdenum stainless steel plate and low carbon steel plate, stainless steel plate, high molybdenum high purity stainless steel plate etc.. According to the characteristics and application of classification of stainless steel 409 , divided into nitric acid resistant stainless steel plate, stainless steel plate, resistance to acid corrosion of stainless steel plate, the stress corrosion of stainless steel plate, stainless steel plate. According to the classification features of steel plate, stainless steel plate, divided into low temperature non magnetic stainless steel plate, stainless steel plate, superplastic free cutting stainless steel plate etc.. Now commonly used classification methods are classified according to the characteristic of chemical composition structural characteristics and the steel plate and a combination of both. Generally divided into martensitic stainless steel, ferritic stainless steel, austenitic stainless steel, duplex stainless steel plate and precipitation hardening stainless steel plate or stainless steel plate and divided into chromium nickel stainless steel plate two categories. Typical use: uses a wide range of pulp and papermaking equipment, heat exchanger, mechanical equipment, dyeing equipment, film processing equipment, pipeline, the coastal areas of the exterior of the building materials etc..
Two hot rolled and cold rolled stainless steel plate according to the method of Wuxi branch, including the plate thickness of 0.5.10-885 mm 72938 thin cold plate and 4.5-100 mm.

Stainless steel bathroom cabinet rust skills
About sanitary water leakage phenomenon , already accustomed to seeing strange , a lot of friends often trouble for these events.
Here stainless steel bathroom cabinet moisture problems , give us mention some recommendations.
Cabinet panel representing a large space in the bathroom furniture , would like to choose a good stainless steel bathroom cabinet , will certainly be familiar with its manufacturing materials . Choose waterproof box board must not only meet the national environmental protection standard E1 material is the most important .
stainless steel factory cabinet in the screening process, consumers will definitely want to look at the details on the front . After taking two- decorating backplane can complete veneer MDF substrate exposed to prevent the water from the cabinet no longer have the opportunity to enter the back plate is a good helper waterproof moisture . In real life, can not always do a very thorough elimination after bathing in the water droplets and vapor everywhere . Back veneer is not only waterproof , but also extends the life of furniture cover god.
Screening bathroom furniture will certainly pay attention to the small local animal design, this is the crux of the success factors buy furniture . Meticulous screening certainly can not put small parts, whether professional furniture manufacturing through intimate knowledge of the details of the inspection can be done . After individual bathroom furniture using for some time , the floor began to sink cabinet above the deformation , the cause is hidden in the cupboard in the pipe condensation droplets soaked furniture left in the bottom of the tank . Not easy to be a central focus to the protection and attention due to neglect and significant effect.
Often need to punch in the box when the device board cut stainless steel bathroom cabinet , multi-functional sealing tape can wrap a sheet cutting edge , play better waterproof effect. Choose the right bathroom furniture is just the first step. Drops of water and water vapor is pervasive , the choice would want to completely waterproof professional brand , be waterproof from all aspects .

Stainless steel rusting occurs
Stainless steel , by definition refers to the resistance of air , steam, water and other corrosive medium and weak acid, alkali , salt and other chemical etching medium corrosion of steel , also known as acid-resistant stainless steel. But in the practical application of them , and some stainless steel but the accident rusty . Stainless steel rusting occurs , there may be several reasons:
First, between the natural corrosion.
This material does not contain titanium and niobium have a tendency to intergranular corrosion. Adding titanium and niobium, together with the stabilization process can reduce intergranular corrosion. Corrosive chemicals in the air or in a high- alloy steel resistant to corrosion , stainless steel is a beautiful surface and good corrosion resistance , without going through the plated surface treatment, and play inherent in surface properties of stainless steel , for use in multi- an aspect of steel , stainless steel is often called . Representative of the performance of 13 chrome steel , 18-8 chrome -nickel steel alloy . From the perspective of metallographic analysis , because the stainless steel contains chromium chromium film formed on the surface leaving a thin , the membrane separating the oxygen from corrosion-resistant steel intrusive role . To maintain the inherent corrosion resistance of stainless steel , the steel must contain more than 12 % chromium. The need for welding applications. Lower carbon content makes it close to the weld heat affected zone to minimize carbide precipitation , and carbide precipitation may lead to intergranular corrosion of stainless steel welded erosion in some environments .
Second , without solution treatment.
No alloying elements dissolved in the matrix , resulting in tissue matrix alloy content is low, poor corrosion resistance.
Thirdly, the presence of chloride ions in the environment .
Widespread presence of chloride ions , such as salt / sweat / sea / sea / soil , and so on . Stainless steel in the presence of chloride ions in the environment, the corrosion rapidly , even more than the ordinary low carbon steel. Therefore, the use of stainless steel environment requirements, and require frequent cleaning to remove dust, keep it clean and dry.
