Column in front of a large ancient palaces, tombs and other decorative building, material selection and more generally a huge stone as raw material, which is a traditional Chinese architectural forms. Chinese table base generally consists of squatting beast, Beaulieu column, Cheng Lu disk and its composition. Multi-pillar carved dragon and phoenix patterns, stuck in the upper part of the cross carved in stone. Chinese table is a landmark building, has become one of the symbols of China. Chinese table is used in palaces, tombs outside the roads, also known as Shinto columns, stone looking columns. Pillars of ancient Greek architecture have Victoria style, O'Neill style, Corinthian and so on. In our modern society, according to the material points uprights common are: cement columns, steel, wood columns, galvanized steel columns and pillars. One stainless steel column - stainless steel column 304 is our most common in life, is the most commonly used. 304 stainless steel is a versatile stainless steel material, anti-rust performance than the 200 series stainless steel stronger. Also relatively good high temperature, the general temperature limit is less than 650 ℃. 304 stainless steel with excellent corrosion resistance and good energy between resistance to intergranular corrosion. For oxidizing acid, in the experiment: the concentration of ≤65% below the boiling temperature of the nitric acid, 304 stainless steel with a strong anti-corrosive, alkaline solutions and most organic and inorganic acids also have good corrosion resistance ability, so use material made of stainless steel 304 - 304 stainless steel column is very correct choice column in front of a large ancient palaces, tombs and other decorative building, material selection and more generally a huge stone as raw material, which is China a kinds of traditional architectural forms.

Stainless steel column 304 Mechanical properties are as follows: mechanical properties at room temperature and annealed 304L austenitic stainless steel plate 304, ASTM standard A240, ASME standard SA-240, required minimum mechanical properties as follows: Performance ASTM A240 and ASME SA Minimum requirements of the mechanical properties of -240 304 304L 304H 0.2% offset yield strength psMPa30,20525,30,000 205 ultimate tensile strength, psiMPa75,000 515 70,000 485 75,000 515 extending dividing ratio (2 inches or 51mm) 40.0 40.0 40.0 Hardness, maximum.

Stainless steel column 304 welded: austenitic stainless steel is considered to be the most weldable alloy steel, can all fusion welding, or resistance welding. 304,304L is a typical austenitic stainless steel. To consider the production of austenitic stainless steel welded joint of two factors: 1) maintain their corrosion resistance, 2) to avoid cracking. Material is the formation of the welding process temperature ladder, from the pool to the melting temperature of the welding point a little far away from the ambient temperature. The higher the carbon content is welding material, the welding thermal cycle is easier to cause precipitation of chromium carbides, affect the corrosion resistance of the material. In order to maintain the corrosion resistance of materials at the best level, so in the welded state job, you should choose a low-carbon materials (304L). Another approach is the use of fully annealed dissolved chromium carbide, so that the carbon content of the material recovery standard high level of corrosion resistance. Metal welding fully austenitic structure during the welding operation more susceptible to cracking. Thus, 304 and 304L alloy with a small amount of ferrite, to minimize cracking susceptibility, to achieve re-curing effect. When the 18-8 austenitic alloy welded to the steel, usually 309 alloy (23% -13.5% nickel chrome) or nickel-based solder. Heat-treated stainless steel column: austenitic stainless steel by heat treatment can clear cold forming chromium carbide precipitation and dissolution of the side effects produced. The best way to achieve these two requirements heat treatment is carried out in a solution annealing 1850 ° F to 2050 ° F (1010 ° C to 1121 ° C) temperature range. Cooling down from the annealing temperature 1500-800 ° F (816 ° C - 427 ° C), should be sufficient to avoid chromium carbide precipitation. These materials can not be hardened by heat treatment. Clean stainless steel column 304: No matter how kind corrosive, stainless steel processing and use, must maintain its surface clean. When using inert gas welding process, the welding process and the formation of rust skin through a stainless steel brush to remove slag. Plain carbon steel brush will leave the surface of stainless steel particles, these particles will eventually lead to surface rust. In demanding circumstances, weld region subjected to rust solution treatment (e.g., a mixed solution of nitric acid and hydrofluoric acid), formed during the welding process can be washed off the rust scale and slag. Inland, light industry materials, less maintenance required, only the mask area is sometimes necessary to use pressurized water. Heavy recommend regular cleaning to remove accumulated dust, the dust may eventually cause corrosion and damage the surface appearance of stainless steel. Stubborn stains and sediment can be abrasive cleaners and fiber brush, sponge, steel wool scrubbing. Stainless steel wool can leave permanent scratches in a smooth stainless steel surface. Many stainless steel should be regularly cleaned and disinfected. With a special equipment is usually caustic soda, organic solvent, acidic solution (a phosphate or sulfate) cleaning. Strong reducing acids (such as hydrofluoric acid or hydrochloric acid) may cause damage to the stainless steel. After the cleaning solution, rinse thoroughly with water stainless steel. Appropriate design helps to clean. With rounded corners, fillets, seamless equipment, help clean and polish the surface. 304 stainless steel column applies more for decoration, such as villas, hotels, exhibition halls, hotels and so on. Can also be used for balcony guardrail, fence and other hospital corridor. 304 stainless steel column and diverse styles novel, colorful, durable, strong, gorgeous atmosphere.
