304 stainless steel is beautiful. It occupies most of the daily necessities in our daily life, such as stainless steel water cups, stainless steel kitchen utensils, stainless steel household appliances, stainless steel sheet for decoration etc.
The brushed stainless steel and polished stainless steel are the most common products. Its application probability is diversified, because of its preservatives, high-strength and durable compressive strength are stronger than ordinary steel, easy to clean and its beauty attracts people's attention. So 304 grade stainless steel is very popular in many fields!
So, what exactly is SUS304 stainless steel? To talk about 304 stainless, it is necessary to understand stainless steel.
Stainless steel does not refer to a certain material, but a large category. At present, hundreds of stainless steel materials have been used in different industries on the market. For stainless steel, chromium is a material that prevents products from rust, while nickel is a corrosion-resistant material.
Stainless steel can maintain luster and rust in the air, mainly because stainless steel contains a certain amount of chromium alloy elements (not less than 10.5%), which can form a layer of oxidized film that is insoluble in some media on the steel surface. After adding nickel, the performance of stainless steel is further improved. In many aqueous solutions of acids, alkali and salts, it has good chemical stability, and can still maintain its corrosion resistance even in high-temperature or low-temperature environments.
SS304 is a chromium-nickel stainless steel. 304 is a brand of stainless steel produced according to the American ASTM standard. It is considered food-grade stainless steel. The most important elements of 304 stainless steel are Cr and Ni, but they are not limited to these two elements. The common judgment in the industry is that as long as the Cr content is greater than 18% and the Ni content is greater than 8%, it can be regarded as AISI 304. That's why this kind of stainless steel is called 18/8 stainless steel in the industry.
First of all, 304 stainless steel has stronger corrosion resistance, because the chromium-nickel ratio is 18:8, forming a dense oxide film on the surface of stainless steel, which can isolate the contact between internal iron and oxygen and prevent stainless steel from rusting due to oxidation.
Secondly, 304 stainless steel products are better in safety than products of other materials. The main reason is that the performance of stainless steel products such as 201 and 202 is unstable, and they may rust easily after a period of use. Manganese is commonly found in rust. If the human body consumes too much manganese, it will affect the nervous system. They all cause damage, leading to memory loss or mental depression, but the more stable performance of 304 stainless steel ensures the safety of its use.
In addition, 304 stainless steel products are not only safer, but also more healthy. Nutritionists have pointed out that if trace elements such as chromium and nickel are lacking in the diet for a long time, it will increase the risk of diabetes and cardiovascular and cerebrovascular diseases, while 304 stainless steel contains a certain amount of chromium and nickel, so using for a long time of 304 Stainless steel kitchenware will bring great benefits to the elderly, especially those with such diseases, as well as to teenagers.
