First, referring to FIGS. 1 to 9, the anti-bacterial mirror tank having a double partition structure according to an exemplary embodiment of the present invention is used for a village water supply drain, a water purification plant, and a home storage tank. The inner wall 100 and the outer wall 200 It is composed of a double partition wall, the inner wall 100 and the outer wall 200 is made of a stainless material.

For reference, stainless steel [SUS] is excellent in workability, weldability, mechanical properties, etc., but alloy elements such as chromium are added to improve the defects of steel that is rustable in air or in aqueous solution. It is also called the river, the river.

In general, compared with ordinary carbon steel, the corrosion resistance is excellent, but it does not mean that it will never rust, so when it is in some environment, it causes local corrosion, for example, formal, crack corrosion, intergranular corrosion, stress corrosion cracking.

The excellent corrosion resistance of stainless steel is due to an oxide film which is a passivation film formed on the surface thereof. If a passivation film is formed on the surface, it protects the underlying iron and prevents further rust. More than 12% (weight) of chromium is required for steel to achieve sufficient corrosion resistance in the natural environment. When nickel and molybdenum are alloyed together with chromium, corrosion resistance is further improved, so that they can be used in special environments such as chemicals and chemicals.

Stainless steels are classified into mardenite series, ferrite series, austenite series, austenite-ferritic two-phase series and the like according to the main metal structure composition.

① Martensitic stainless steel: It contains 12-18% chromium and 0.10-1.20% carbon and is quenched and tempered to use as a structure of martensite or martensite chromium carbonide. Among these types of stainless steels, precipitation hardening stainless steels are strong stainless steels which have increased strength by precipitation hardening such as NiTi and NiAl. As it is very hard and strong, it is used for members requiring corrosion resistance and hardness and wear resistance, for example, cutlery, surgical instruments and tools.

(2) Ferritic stainless steel: Cr containing 0.20% or more of 12 to 27% chromium. In general, there are 13 chrome steel, 18 chrome steel, and 25 chromium steel. Recently, due to the development of steelmaking technology, it is difficult to cause stress corrosion cracking, and it is made of high-purity ferritic stainless steel which reduces carbon amount and adds about 2% of molybdenum. Since hardenability is hardly hardened, corrosion resistance is comparatively good, and nickel is hardly contained, it is cheaper than an austenite system. It is used for household goods such as tableware, building materials, and equipment for chemical industry.

③ Austenitic stainless steel: 13 to 30% of chromium, 6 to 20% of nickel, and 0.10% or less of carbon. Typical are 18 to 8 stainless steels with low carbon containing 18% chromium and 8% nickel. In order to further improve the corrosion resistance, the strength of 1 to 3% of molybdenum is often used. Most of the demand for stainless steel is stainless steel of this type, and since it is excellent in corrosion resistance and oxidation resistance at high temperature, there are applications for chemical industry, petroleum industry, nuclear reactor, etc. in addition to household goods and building materials.

④ Austenitic-ferritic two-phase stainless steel: 18 to 30% of chromium, 6 to 12% of nickel, 0.10% or less of carbon, and finely adjusted crystal grains by roughly half of austenite and ferrite by heat treatment. · Stainless steel with good workability and high strength. It is used in petroleum industry, chemical industry, seawater receiving equipment, etc.

STS 304 is a stainless steel that is used for the widest use. Since Ni contains Ni, it has better corrosion resistance, heat resistance, low temperature strength and good mechanical properties than Cr series. Processability is large and harden by heat treatment, and it is not magnetic.
