The stainless steel pipe factory introduced the materials and grades that meet GB/T3280 material suitable for stainless steel food containers. The stainless steel food containers used stainless steel materials related issues when pointed out: In accordance with the "national standards for food safety stainless steel products" (GB 9684-2011) , should use materials that meet the relevant national standards, that is, in line with GB/T3280 materials and brands. In China's newly issued stainless steel cold-rolled steel sheet and strip standard (GB/T3280-2007), a total of 71 brands, suitable for stainless steel cooking utensils, the manganese content of not more than 2%.

Only 3 of the 71 brands have manganese content greater than 2%:
1,015Cr24Ni22M08Mn3CuN (manganese content 2-4%)
2, 022Cr24Ni17M05Mn6NbN (manganese content of 5 to 7%)
3, 022Cr23Ni4M0CuN (manganese content ≤ 2.5%)
The first two grades are super austenitic stainless steels used in harsh environments such as ocean engineering, seawater desalination, pulp production and flue gas desulfurization plants. The cost is high and processing is extremely difficult. It is impossible to produce food containers. . The third grade is duplex stainless steel, which is characterized by high yield strength, high deformation resistance, low elongation, and is generally not suitable for applications requiring higher cold forming (such as deep drawing). So far, we have not seen an example of using this brand to make stainless steel food utensils. Because it combines the excellent toughness and weldability of austenitic stainless steels with the higher strength and chloride stress corrosion resistance of ferritic stainless steels, in the chemical industry, the oil refining industry, the transportation of oil and natural gas, and seawater The environment, environmental protection industry, light industrial food machinery, and high-strength structural parts have a wide range of uses.

2. The general spray gun comes with a pressurization module, often used as a flushing toilet, but also can facilitate flushing the corner of the toilet, cleaning the basin, cleaning the broom and other functions, after installation, you will find that the function is simply too humane. 3. When installing, you only need to use a three-way angle valve at the toilet access. One way the water goes into the toilet and the other way into the spray gun. There are multiple options for spray gun water pipes, among which explosion-proof bellows and telephone line hoses are the most commonly used, especially telephone line hoses are the most widely used because they do not take up space and are highly stretchable.
