Carbon steel can be used for food contact, but it is necessary to pay attention to the nature and use of food.

First, carbon steel introduction

Carbon steel is a kind of steel with high carbon content, because its internal structure contains a lot of carbon elements, with high hardness and strength, is widely used in machinery manufacturing and construction engineering and other fields.

Second, carbon steel characteristics

Carbon steel has a high hardness and strength, but also relatively easy to be machined and welded. However, carbon steel has poor corrosion resistance and is easy to be corroded and oxidized, so it is necessary to pay attention to its use environment and maintenance.

Third, carbon steel and food contact

In the food processing and manufacturing process, carbon steel is often used to make contact materials, such as POTS, POTS, bowls, etc., but it is necessary to pay attention to the nature and use of food. Some acidic foods and alkaline foods have strong corrosion to carbon steel, which will cause iron ions in carbon steel to be dissolved, affecting the quality and safety of food. Therefore, carbon steel products need to be processed and treated to improve their corrosion resistance and safety.

Fourth, the application field of carbon steel

Because of its high hardness and strength, carbon steel is widely used in machinery manufacturing and construction engineering. At the same time, in the field of food processing and manufacturing, carbon steel is also used to make some durable food contact materials, such as cast iron POTS, teppanyaki and so on.

fifth. Summary

Carbon steel is an important material with high hardness and strength, but it is also widely used in the manufacture of food contact materials. However, it is necessary to pay attention to the nature and use of food to improve its corrosion resistance and safety.
