201 and 202 grade stainless steels, which are included in the austenitic group, contain less nickel than 304 grade steel. Therefore, it does not have a magnetization effect like 304 grade steel.
When we examine their chemical solubility, it is seen that 304 grade steel contains 8% nickel and 18% chromium. 201 quality stainless steel contains 1% nickel and 10% cream. For this reason, the difference between 201 and 202 quality stainless steels cannot be easily understood with a magnet.
When examined in terms of appearance, there is not much difference in 304 and 201 stainless steels. In salt and acid tests, 304 stainless steel lasted 250 hours while 201 stainless steel lasted 190 hours. In other words; chromium and nickel and chromium, manganese and nickel grades do not have magnetic properties, but with the developing technology, we see that chromium, nickel and manganese triple austenitic quality products are expanding. In terms of production costs, in stainless steels processed in terms of production costs, while the basic components cause corrosion and form the chromium oxide layer, the basic chromium costs are not much in preventing corrosion. However, the production cost of molybdenum, a component that increases the corrosion resistance factor, and nickel, which makes production even easier, is very high. Due to these costs, it requires a high cost to produce products in the austenitic group with 304 and 316 numbers.
If we examine it in terms of usage areas, it is easily used in areas such as cooking equipment, kitchen products, low surface quality features, industrial kitchen utensils.
It is available in the market in rolls, sheets, pipes, profiles and strips.
