Which SS grade is best for railing Fittings?
Stainless Steel grade 304 may be the best choice for interior and exterior railing system designs-especially if the application is away from large amounts of saltwater and is not exposed to extreme conditions. Although 304 stainless steel is usually used for indoor applications, it is also suitable for protected outdoor applications.
Grade 304 stainless steel can be utilized in indoor as well as outdoor applications performs where conditions are not overly harsh or extreme, or where the railing system is protected from the environment.
For swimming pool fencing or railing system near coastal areas, grade 316 or duplex 2205 stainless steel can give better resistance in these harsh environments.
Whether you 304 stainless steel or 316 stainless steel for your railing system, consider your application and the total budge when deciding which material to use. Grade 316 stainless steel is more expensive than 304 stainless steel. Grade 316 stainless steel contains more nickel which makes it corrosion resistant to rust.

Stainless Steel Handrail Fittings Maintenance
Stainless steel handrail fitting is not maintenance free but is maintenance friendly.
Outdoor stainless steel railings need to be cleaned periodically, especially in coastal areas or swimming pools.
Washing stainless steel railing fittings with a mild detergent will help with reducing tea staining.
Please note that handrail fittings with deep gap or narrow crevice designs require more regular maintenance.
In coastal location or swimming pools, stainless steel handrail fittings with highly polished surface are recommended. The smoother the surface finish, the better.
Satin finished handrail fittings should be far away from high salt environments. Rough surface f

Research on Factors Affecting Surface Roughness of Investment Castings
During the process of casting and metal liquid solidification, the surface of the casting will oxidize due to the high temperature, and the oxide layer will be uneven. The metal oxide on the surface of the casting may interact with the oxide in the shell to promote the uneven surface of the casting, which is remarkable. Increase the roughness of the surface of the casting.
Cooling of the casting under a protective atmosphere is an important part of obtaining a high quality surface. After the casting is cast, it is cooled under an inert gas or a reducing protective atmosphere to prevent oxidation and prevent surface decarburization, and to protect the surface of the casting from the oxidation temperature. The surface of the casting with good surface protection is silver grey, silver white or colored oxidized color after shelling. Cleaning has a great influence on the surface roughness of investment castings. The as-cast surface roughness of investment castings is originally low, and blast cleaning or water sand cleaning should be used to clean the surface. The blasting method is better than the surface roughness of the shot peening casting by 2 or more. Peeling often destroys the as-cast surface.
For stainless steel investment castings with high hardness, shot peening can also be used to improve efficiency, but the diameter of shot peening should be less than 0.3mm.
In short, the surface quality of castings is an important quality index for investment castings. The surface quality includes two related and not identical concepts of surface roughness and surface defects. Surface roughness refers to the uniform microscopic unevenness of the surface of the casting. Castings with low surface roughness can be produced only by preventing serious defects on the surface of the casting, and the surface roughness of the casting is low to achieve high dimensional accuracy.
There are many factors affecting the surface roughness of investment castings.

Prevention and Correction of Deformation of Investment Castings
Investment casting is determined by its process, the production cycle is long, and there are many factors affecting the deformation, which is easy to cause deformation of the precision casting. The deformation of the precision casting not only adds a lot of work to the cleaning and finishing process, but also causes more waste if it is improperly controlled and handled. Therefore, in actual production, it is necessary to control various processes, strictly enforce process discipline, and reduce the deformation of precision castings by taking effective measures. The so-called deformation means that the shape and size of the cast part after casting and cleaning do not match the pattern. The main performance is as follows: the circular parts become elliptical; the vertical wall of the box can not meet the requirements of the model; all kinds of opening gears increase or decrease; the plate and strips are twisted and warped, and the flatness is unqualified. The concentricity and relative position of the porous casting are unqualified. The causes and processes of the deformation are roughly classified into the following categories: deformation caused by the shape of the shell; deformation due to improper placement of the casting and heat treatment.
According to the above analysis and combined with the actual production control situation, it is very important to prevent the deformation and deformation correction of the precision casting.
1. The deformation of the casting mold causes deformation of the precision casting
In the investment precision casting, the paste molding is used. Therefore, in the production process of the wax mold, the solidification process of the paste molding material, that is, the cooling process, causes the wax mold to cause certain deformation. If it is not prevented and effectively controlled, the precision casting will be deformed. , affecting the quality of the product, the dimensional accuracy of the wax mold directly det

The total output of castings in China is affected by the decline in the output of steel castings
Castings can be divided into cast steel parts, cast iron parts, ductile iron parts, aluminum alloy castings, etc. according to the material. It is reported that from January to February in 2013, the total output of steel castings in China experienced a year-on-year decline. This has affected the total output of castings in China in 2013 to some extent.
According to relevant inspection data, the total output of steel castings in China in January-February 2013 was 1.5937 million tons, a year-on-year decrease of 3.89% year-on-year. In terms of steel output from various provinces and cities, from January to February 2013, Henan Province The output of steel castings was 369,500 tons, a year-on-year decrease of 12.43%, accounting for 23.19% of the country's total output; Ningxia yield of steel castings was 6,241.84 tons, a year-on-year decrease of 27.1%; Anhui's steel castings were 113,911.77 tons, a year-on-year decrease of 1.99. %; The output of steel castings in Sichuan was 102,207.59 tons, a decrease of 1.58% from the same period of 2012.
This time, the production of steel castings in most parts of the country has been accompanied by a declining phenomenon, mainly due to the macroeconomic recession at home and abroad. According to the current status quo, relevant experts believe that the probability of rapid recovery of the foundry industry in the coming period of time Very small, in the short term, it is still unable to get rid of the weak status. Obviously, the increase in the output of steel castings will not be large, which will affect the total output of castings in China more or less.
