How does external polishing affect the performance of SUS304 stainless steel non-stick frying pans?

In modern kitchens, SUS304 stainless steel non-stick frying pans have become a powerful assistant for many cooking enthusiasts due to their excellent durability and non-stick properties. People often focus on the key role of its internal coating in achieving the non-stick effect, but easily overlook the impact of the external polishing process on the non-stick performance of the frying pan. So, how does external polishing affect the performance of SUS304 stainless steel non-stick frying pans?

SUS304 stainless steel itself has good corrosion resistance and certain strength, and is a high-quality material for making cooking utensils. In the process of making frying pans, external polishing is an extremely important process. After careful polishing, the surface roughness of the outer surface of the pan body is significantly reduced, and it can achieve a nearly mirror-like flatness. This change seems to be only about appearance, but it actually has a profound impact on the performance of the frying pan.

From the perspective of heat transfer, this smooth surface has a positive optimization effect on heat transfer. When the frying pan is placed on the stove to heat, the heat needs to be evenly transferred to the entire bottom of the pan to ensure that the food is evenly heated during the cooking process. The nearly mirror-like surface after external polishing reduces the obstacles in the heat transfer process. Compared with the unpolished or poorly polished pot body, the heat can be spread more quickly and evenly to all parts of the bottom of the pot. This is because the smooth surface reduces the unevenness at the microscopic level and reduces the thermal resistance. The reduction in thermal resistance means that heat can be conducted more efficiently, avoiding the occurrence of local overheating.

Local overheating is one of the important reasons for food sticking to the pot. When the temperature of a certain area of ​​the bottom of the pot is too high and the temperature of other areas is relatively low, the food will quickly dehydrate and carbonize in the high-temperature area, thus adhering tightly to the surface of the pot. After the SUS304 stainless steel non-stick frying pan is polished on the outside, the heat can be evenly distributed, and the food is heated uniformly at all positions in the pot. For example, when frying eggs, the whole egg can be heated at the same time, the egg white is evenly coagulated, and the yolk can reach the ideal degree of doneness, without the situation of one side being burnt and the other side being undercooked, which greatly reduces the risk of food sticking to the pot due to excessive local temperature.

In addition to its role in heat transfer and preventing local overheating, external polishing also plays a role in keeping the pot clean, which is indirectly related to non-stick properties. The smooth exterior of the pot is not easily contaminated with oil and food residues. During cooking, splashed grease and food particles are not easy to adhere to the smooth surface after contacting it. Even if there is a small amount of contamination, it can be removed by simply wiping or rinsing during cleaning. Keeping the exterior of the pot clean helps maintain the overall heat transfer efficiency of the pot. If a large amount of oil and residue accumulates on the outside of the pot, these substances will form an insulating layer, affecting the transfer of heat from the stove to the bottom of the pot, which may lead to uneven heat distribution and increase the possibility of food sticking to the pot.

In addition, the SUS304 stainless steel frying pan after external polishing has also greatly improved in appearance. The smooth mirror-like surface of the pot not only gives people a delicate and high-end visual experience, but also enhances the user's pleasure during the cooking process. This combination of aesthetics and practicality further highlights the importance of external polishing technology in improving the overall quality of the frying pan.

The external polishing process has a significant impact on the non-stick performance and overall quality of the SUS304 stainless steel non-stick frying pan by optimizing heat transfer, preventing local overheating, keeping the pan clean, and improving aesthetics. It works together with the internal coating to provide users with an excellent cooking experience. When choosing a SUS304 stainless steel non-stick frying pan, paying attention to the quality of the external polishing process can help consumers choose a product with better performance and add more convenience and fun to kitchen cooking.
