What are the differences between industrial and civil stainless steel?

In an article I shared some time ago, I mentioned that some bad manufacturers use industrial steel as the production material of stainless steel water cups. So some friends left a message to question that the cost of industrial stainless steel is higher than the cost of civil food-grade stainless steel used in the production of stainless steel water cups, and manufacturers will not use this material. http://www.umbottle.com/ProductsDetail-VB-10438.htmlToday, I will use my shallow knowledge of materials to share with you what are the differences between industrial and civil stainless steel? After the analysis, I don’t need to answer some questions anymore. I believe some friends have also understood.

What is industrial grade stainless steel?

Industrial grade stainless steel, as the name implies, is stainless steel mainly used in the field of industrial production. Since stainless steel is an alloy material, the main components include metal elements such as iron, chromium, and nickel. http://www.umbottle.com/ProductsDetail-VB-10438.htmlAt the same time, due to different industrial production types, different environments, and different functions of stainless steel, there are many types and models of industrial grade stainless steel. These different types of industrial grade stainless steel have different corrosion resistance, hardness, wear resistance and other properties. Different models and different performances are suitable for various harsh industrial environments, such as chemical equipment, marine engineering, energy equipment and other fields.

What is civil grade stainless steel?

Civilian-grade stainless steel, as the name implies, is stainless steel that is mainly used in daily life, not limited to stainless steel used in kitchenware. http://www.umbottle.com/ProductsDetail-VB-10438.htmlFor example, stainless steel used in construction is civil-grade stainless steel, and stainless steel used in medical applications is also civil-grade stainless steel, although it is medical grade. Stainless steel used in home, bathroom, toys, kitchenware, etc. are all civil-grade stainless steel.

Civilian-grade stainless steel also has a variety of models, and also has corrosion resistance, hardness, and wear resistance. However, since the environment in which civil-grade stainless steel is used is relatively less harsh and harsh than that in which industrial-grade stainless steel is used, the performance indicators of most materials are not as good as those of industrial-grade stainless steel. http://www.umbottle.com/ProductsDetail-VB-10438.htmlHowever, food-grade stainless steel in civil-grade stainless steel has special requirements for materials, so both the material composition and the material process are very high. Therefore, in many stainless steel comparisons (civilian and industrial), the cost of food-grade stainless steel is relatively high.

The difference between industrial grade and civil grade stainless steel

Different composition: Industrial-grade stainless steel usually contains a higher proportion of alloying elements such as chromium and nickel to enhance its corrosion resistance and mechanical properties, http://www.umbottle.com/ProductsDetail-VB-10438.htmlwhile the alloy composition of civilian stainless steel is relatively low.

Different performance requirements for different use environments: Since the use environment of industrial-grade stainless steel is relatively harsh, the performance requirements for the material will be higher. http://www.umbottle.com/ProductsDetail-VB-10438.htmlThis includes corrosion resistance, high temperature resistance without deformation, wear resistance, etc. Civilian-grade requirements are relatively low, except for food-grade stainless steel used in kitchens.

Different surface treatment processes: Industrial stainless steel often needs to undergo surface treatment, such as polishing, pickling, etc., to ensure its surface smoothness and corrosion resistance; http://www.umbottle.com/ProductsDetail-VB-10438.htmlwhile civilian stainless steel, especially food-grade stainless steel used in kitchens, has a more delicate and responsible surface treatment process.
