What is the difference between 403 and 304 stainless steel

Taboos for using stainless steel products

Do not use strong alkaline detergents for cleaning. When cleaning stainless steel kitchenware or tableware, we need to be careful not to use strong alkaline cleaning agents such as baking soda, bleach, etc. The metal elements in them may undergo electrochemical reactions and produce some harmful elements.

The advantages of stainless steel kitchenware in kitchen engineering

Durable: Stainless steel cookware is more durable than tin pots. Tin scratches, chips, and dents are easy, but stainless steel does not. In addition, tin products sometimes deform at high temperatures, while stainless steel kitchen products can withstand the heat and maintain their shape and form; For example: stainless steel frying pans, stainless steel soup pots, stainless steel props, etc.

What are the reasons for stainless steel rusting

1. Stainless steel also has other metallic substances on its surface, which can easily cause electrochemical corrosion and rust. 2. Stainless steel also has stains, such as fruit juice, which can be said to cause organic acids under the action of water and oxygen. After too long, rust will also appear. 3. Stainless steel may also have some acid, salt, and other stains on its surface, which can cause localized corrosion and lead to stainless steel rusting. Summary: This concludes the introduction of several models of stainless steel. The commonly used models include 301, 304, 306, 309S, 310S, etc. You can choose according to your own needs.

Why can some stainless steel tableware be placed in the microwave

Whether stainless steel tableware can be placed in a microwave depends on whether its material composition and structural design will conflict with the heating principle of the microwave. To understand this, it is necessary to first clarify the heating logic of the microwave oven, and then analyze the key characteristics of "safe stainless steel tableware".

Is plastic or stainless steel better for the freshness box

The selection of fresh-keeping boxes mainly depends on usage needs, with food grade PP plastic and stainless steel each having their own suitable scenarios. The bottom of the PP material fresh-keeping box is marked with the number 5, which is lightweight and has excellent sealing performance for the lid. The soup is not easy to leak when inverted, and the biggest highlight is that it can be directly placed in the microwave for heating. It is very convenient for daily office workers to heat meals and thaw ingredients. However, long-term storage of acidic foods and repeated high-temperature heating can lead to aging and yellowing, and surface scratches can easily leave oil stains and breed bacteria, making it unsuitable for long-term pickling of kimchi and soaking of sour and spicy side dishes. Stainless steel fresh-keeping boxes have stronger material stability and are resistant to acid and alkali corrosion. They are more secure for storing pickled foods and leftovers in refrigeration. They can be placed in steamers and disinfection cabinets for high-temperature sterilization, are resistant to falling, durable, and not easily damaged, and will not absorb food odors. The disadvantage is that it cannot be microwave heated, the box body conducts heat quickly, and the feeling of holding hot food is relatively hot. Frequent microwave reheating and portable bento boxes are preferred for daily use, and compliant PP fresh-keeping boxes are preferred; For long-term refrigerated storage, pickling of food, pursuit of health and durability, and for children's use, stainless steel freshness boxes are preferred. When purchasing, avoid low-priced and low-quality products without material labels.
