The Use of Stainless Steel in Microwave Ovens
The so-called stainless steel microwave oven refers to a microwave oven whose cavity is made of stainless steel.
The so-called stainless steel is alloy steel with a certain proportion of special elements such as nickel and chromium and smelted by a special process, which has high corrosion resistance.
There are many types of stainless steel because of its different compositions and melting processes. Among them, the austenitic stainless steel is not easy to be magnetized due to the particularity of the internal molecular structure. The microwave oven cavity made of stainless steel is characterized by high surface strength, higher temperature resistance, and resistance to rust.
In the surface coating process of the ordinary steel plate furnace chamber, if accidentally bumped, the surface coating layer will fall off or crack and lose its anti-rust effect on the ordinary steel plate. Compared with the ordinary steel plate furnace cavity with surface coating treatment, the stainless steel furnace cavity guarantees that it is not easy to rust from the steel plate material. Even if a large pit is bumped, it will not lose its “stainless” characteristic.
It has become a consensus that stainless steel is not easy to rust. For stainless steel microwave ovens under general household environment and usage conditions, it can also be considered that the stainless steel oven cavity will never rust. On the other hand, the ordinary steel plate furnace cavity with surface coating treatment may also rust after long-term use, especially in the corners of the furnace cavity.
Of course, this is not to say that the ordinary steel plate oven cavity that has been surface coated is easy to rust. Judging from the current materials, process level, manufacturing cost, and market acceptance, ordinary steel plate microwave ovens are not in Disadvantages, not to mention the trend of being eliminated because of the introduction of stainless steel microwave ovens.
As for the evaluation of stainless steel microwave ovens with higher heating effects and more energy-saving and time-saving in some media, it is inevitably a bit too one-sided. The surface resistance of stainless steel material is lower than that of ordinary steel plate material treated by surface coating. Under the action of microwave, its surface eddy current is also smaller, which shows that this material has low microwave loss and high reflectivity. However, under general household conditions, this difference is not easy to see.
At present, among domestic microwave oven brands, Galanz stainless steel microwave ovens have a relatively complete variety.
Compared with imported microwave ovens, the price difference is about 1200-1600 yuan, and the performance and quality are comparable to imported products. It is an ideal brand for ordinary families. As for the specific items that we should pay attention to when purchasing a stainless steel microwave oven, it is the same as that of ordinary microwave ovens.
