Sanitary pipe fittings have good corrosion resistance, heat resistance, low temperature strength and mechanical properties. It is resistant to corrosion in the atmosphere. If it is an industrial atmosphere or a heavily polluted area, it needs to be cleaned in time to avoid corrosion. It is suitable for food processing, storage and transportation. Has good processing properties and weldability. The physical performance characteristics of sanitary stainless steel pipe fittings at low temperature: 1. Low temperature processing --- The martensitic stainless steel is quenched from austenitizing temperature and then cooled to a very low temperature to promote the quenching method to produce martensite. Suitable for easy production of retained austenite stainless steel. Regarding the low-temperature brittleness of ferritic stainless steel pipes like carbon steel, under low temperature conditions, austenitic steel does not exist. Therefore, ferritic or martensitic stainless steel pipe fittings produce low-temperature embrittlement, while austenitic stainless steel or nickel-based alloy does not show low-temperature embrittlement. Ferritic stainless steel pipe fittings such as SUS410 (13Cr) and SUS430 (18Cr) show a sharp drop in impact value at low temperatures. Therefore, it is necessary to pay special attention when using it at low temperature. As a method to improve the impact toughness of ferritic stainless steels, a high-purification process can be considered. By controlling the C and N grade levels and improving the embrittlement temperature in the range of -50°C to -100°C, it is possible to use it in freezing-related engineering. In recent years, SUS430LX (18Cr-Ti, Nb-LC) and SUS436L (18Cr-Mo-Ti, Nb-LC) have been applied to the shells of refrigeration appliances. 2. Low temperature embrittlement --- In a low temperature environment, the deformation energy is small. In a low temperature environment, the phenomenon that elongation and reduction of area decrease is called low temperature embrittlement. Mostly produced on the body-centered cubic structure of the ferrite series. The above mentioned is about the physical performance characteristics of sanitary stainless steel pipe fittings at low temperature. I hope it will be helpful to you.
