Comparison of common plates for stainless steel tanks

Hot dip galvanized steel water tank
Currently on the market the most common of several stainless steel tanks, the stainless steel plate generally have: 304,316,444,201 and so on. In general, stainless steel tanks often use SUS304 sheet, 316 sheets are mostly used in the case of poor water quality, 444 sheet in the coastal area to use more. As for the 201 plate, should not be used, but because of its cheap, often by some cheap, figure small profits of profiteers secretly use. Several material properties are as follows:
     one. SUS304 has good corrosion resistance, heat resistance, anti-rust ability. Non-magnetic, excellent processing performance and welding performance, the oxidation of acid has a strong corrosion resistance, the lye and most of the organic acids and inorganic acids also have a certain degree of corrosion resistance, is the most conventional water tank manufacturing the most widely selected The (If it is life drinking water tank, must use food grade 2B board).

     two. SUS316 has good welding performance, pitting resistance, especially excellent high temperature strength, excellent resistance to intergranular corrosion; also has good resistance to chloride erosion performance, in the sea and other various media, corrosion resistance than 304 good. So it is usually used in marine and chemical industry environment and other harsh conditions. But its market price is higher, only according to the actual needs of selective use.
     three. SUS444 is a high corrosion resistant ferritic stainless steel with high yield strength and strong magnetic properties. Compared with other stainless steel, the biggest advantage is the resistance to chloride stress corrosion cracking ability, and its resistance to chloride ion point corrosion is better than SUS304, and SUS316L rather, more suitable for coastal areas of urban water supply tank. But its corrosion resistance is not strong (easy to rust), less than 304 plate, but the price relative to the 304 plate cheaper, according to the actual needs of choice.

     four. SUS201 is a low-nickel stainless steel, short life, poor corrosion resistance, easy to rust, especially acidic, it is easy to corrosion, use it to do the quality of the tank is not guaranteed, infinite trouble. Coupled with its high manganese content, as a drinking water tank is particularly harmful to health. But because of the cheap 201 prices are often some cheap, figure small profits of profiteers secretly use. We recommend no choice.
Excellent selection of durable: the use of excellent performance of austenitic, ultra-low carbon, ferritic stainless steel plate made of. Earthquake resistance, good crack resistance, year-round corrosion. Reasonable installation of simple structure: high-strength stamping plate and the distribution of uniform stainless steel box to increase the box six times the strength of the box, and the force evenly. The tank is made of unit rectangular sheet and concavo-convex plate. The installation is simple and easy to transport. No large-scale lifting equipment and different volume can be assembled on-site.

Stainless steel tank water tank integrated welding, this place is the key to the quality of the round tank quality, some small manufacturers due to the imperfect equipment, in this part of the manual welding is used, hand stack welding prone to The problem is missing welding and welding is not complete, welding situation is common, and the use of stainless steel tank 2 years after the quality is difficult to guarantee, and the large water supply equipment used in the whole computer pulse high-frequency protection straight seam welding, Strong, strong tensile strength, secondary treatment and greatly enhance the anti-corrosion effect, the welding process is perfect, remove the water vapor into the foam layer to reduce the effect of insulation concerns.
