Vintage, medicine and food industry

1. Vintage industry
In the process of beer production, in order to keep the cleanness of the microorganism, the using frequency of acid/ alkali detergent and antiseptic are quite high, and the production equipments should be resistant to the corrosion of the technique environment; besides, the beer is not allowed to contain Fe++, adding the consideration for cleanness, stainless steel is the best choice for the beer production equipments, and the main brand is 0Cr18Ni9. The beer enterprise that has an annual production of 0.2 billion liters will require 2,500 tons of 0Cr18Ni9 steel, shown in the see the following table for detail:

2. Dairy products industry
(1) Milk collecting and storage
After the milk is squeezed out, use cooler to cool it, the cooler is the stainless steel storage tank with cooling mantle layer, the steel brand is 0Cr18Ni9, and the mike tank of the milk tank cart, as well as the matching pipes should all be made of 0Cr18Ni9.

(2) High temperature disinfection and sterilization
The high temperature disinfection and sterilization equipments for milk are made of 0Cr18Ni9; in recent years, the number of the equipments made of 0Cr17Ni12Mo2 is gradually increasing.

(3) Dairy production

3. Medical industry
With the development of modern medical industry, stainless steel has been used in the production equipments in substitution of porcelain enamel plate, copper and zincification plate. Apart from improving the corrosion resistance of the equipments, the main purpose is to improve the cleaning condition to comply with the regulation and requirements of medicine production. In the medical industry, 0Cr18Ni9 is commonly used to make containers, matching pipes, reacting kettle, operation panel, transporting belt, spoon, cover, marble bench and so on.

Under the conditions that often produce stress corrosion and corrosion pitting, use according equipments made of 00Cr17Ni14Mo2, shown in the following table:
