Foil of stainless steel is used as a reliable insulation material during heat treatment details. The most popular today, the thin foil because it is very convenient for practical application. Such a foil can be cut with scissors. In the kiln it protects parts from oxidation and corrosive environment. Distinguish foil disposable and reusable, which comes in rolls, envelopes or bags.
Thanks to optimally balanced composition, stainless steel foil alloyed with chromium, Nickel, molybdenum, exhibits high technological and operating characteristics: heat resistance, resistance to corrosion damage, good resistance to scale formation, which allows her to work effectively in the toughest industrial conditions. The high temperatures in the working area up to 750 °C does not reduce the operating characteristics of the foil. The high content of chromium and Nickel contributes to the formation on the surface of the foil durable oxide coating that protects the material from corrosion and aggressive influence of the hot gas environment.
Use the following steel grades: 08X17H5M3, 09H15N8YU, 12H13, 12X21H5T, 12KH18N9T, 20Х23Н13, 20KH13N4G9, 20X13, 20H23N18. Each of the sheets passes several stages of processing, which is aimed at improving the plasticity, strength properties. Foil stamps 20Х23Н13 can be operated at temperatures up to 1000 °C.
Percentage composition GOST 5632−72.
To increase the strength of steel parts, their technology is subjected to decarburization in the furnace. The material is not oxidized, it is wrapped with foil. With increasing temperature, oxygen reacts only with the foil and does not oxidize the item. Because the foil is very thin, it does not prevent the heat treatment. When the item is hardening, the foil is removed. Today without the use of stainless foil. not do automotive, aircraft, electrical industry, instrument making, food industry.
