Hsn70-1 tin brass is a single-phase brass with trace arsenic in copper and zinc, and the Chinese national standard (gb5232-85) is classified as arsenic and brass.
2. Characteristics and scope of application.
Trace arsenic can inhibit zinc corrosion and further improve the corrosion resistance of the alloy. Hsn70-1 has good mechanical properties. It is used to make heat exchangers and pipes with corrosive liquid. It is widely used in the production of high-strength and corrosion-resistant heat exchangers in inland thermal power plants. In recent years, it has been proved that adding trace boron and nickel to hsn70-1 can better improve the corrosion resistance of the alloy. Hsn70-1 has a tendency of stress corrosion cracking, which must be used to eliminate stress low temperature annealing. Hsn70-1 is easy to crack during hot pressing, and the content of impurities should be strictly controlled.

ORP, also known as oxidation-reduction potential, represents the oxidation-reduction ability of water, and the unit is mV. When the ORP sensor reads a negative number, this means that the substance being measured is a reducing agent, and when the reading is positive, it means that it is measuring an oxidizing agent. The reading of ORP will reflect the degree of pollution or disinfection of water, and it is an important indicator of water quality. Although it cannot independently reflect the quality of water, it can reflect the ecological environment of water bodies in combination with other water quality indicators.
If the ORP value is low, it indicates that the content of reducing substances or organic pollutants in the wastewater treatment system is high, the concentration of dissolved oxygen is low, and the reducing environment is dominant.
If the ORP value is high, it indicates that the concentration of organic pollutants in the wastewater is low, the concentration of dissolved oxygen or oxidizing substances is high, and the oxidation environment is dominant.
Daruifuno online analog ORP sensor has two types of flat platinum and circular platinum, and the measurement range is also different. Customers can choose according to their needs. The simulated ORP electrode is a double-salt bridge design, Ag/Cl reference electrode, and we also have glass material and plastic case packaging models.
