410 stainless steel

What is 410 stainless steel?

410 stainless steel belongs to the general martensitic stainless steel, does not represent food grade, but 410 stainless steel can be made into food grade products. 410 stainless steel has a 0.15% carbon content, 13% chromium, high machinability, and is typically utilized in the blade and valve classes.

410 stainless steel can be used when cooking on fire, but it is mostly used for knives, knives and forks or small spoons. In contrast to stainless steel for cooking, it is important to ensure that the content of chromium elements is not excessive.Although 410 stainless steel can also meet these requirements, it is best to use 304 steel.

Precautions for use of stainless steel products

401 stainless steel is generally used in some places with relatively high hardness but not good rust prevention ability, at this time you can choose to use 410.Stainless steel pot in the process of use, remember to cook or store acidic things, must not choose to use stainless steel to boil Chinese medicine, Chinese medicine contains some bad ingredients, so do not choose this appliance to boil.

In the process of using stainless steel, it must not be empty burned, if burned dry, it will make the surface metal coating of the pot old, very affect the service life.

What are the characteristics of 410 stainless steel?

At present, we can see a variety of stainless steel materials on the market, and these materials have their own characteristics, and have very good sales.There is a stainless steel material called 410 stainless steel, this material has a different performance, which not only includes the performance of use, but also includes the performance of processing.So it has a very good advantage compared with other stainless steel, there are many industries are willing to use this kind of stainless steel, so this material is still relatively common in our side.

410 stainless steel properties

1, like other stainless steel materials, 410 stainless steel has very good strength, and the strength is still very good, so it will be more laborious when processing, but the performance is still very good when using.

2, 410 stainless steel material has a very good characteristics, that is, its weight is relatively light, so it absorbs energy than other metal materials to be lighter, safety performance is very good, so it is used in the automobile transportation industry is relatively wide, this time its body-centered cubic crystal structure plays a very good performance.

3, 410 stainless steel material also has a very special characteristic, that is, its composition does not contain nickel, but also contains a small amount of Ti, Mo, Nb and other elements, so the thermal conductivity of this material is very good, and it also has a very good expansion coefficient and oxidation resistance.Sometimes it can also resist the erosion of some corrosive substances, so we can see that this material is used in parts that are resistant to atmospheric, water vapor and other substances.

4, the most important thing is that this stainless steel rust resistance is very not coarse, in the process of use it can adapt to the external environment, temperature and humidity and other external environment can also be very good, even in the environment is more harsh place it can be used more normal, and long-term use of the basic performance will not be too much affected,This is also an important reason why many industries are willing to choose to use 410 stainless steel, and it does have a good performance in the travel process of use.

410 stainless steel material and other types of expensive material compared to is still very good, not only from its performance, on the other hand, because its cost is relatively low, so the use of this material can enjoy good performance, but also can save a certain cost, which is a lot of producers and buyers are willing to see.

Is 410 stainless steel food grade

410 represents a stainless steel grade, can not represent whether it is food grade, but 410 stainless steel can be made into food grade products.410 stainless steel is a stainless steel grade produced in accordance with the American ASTM standard, which is equivalent to China's 21Cr13 stainless steel.

The so-called "food grade" refers to the stainless steel that meets the national standards for food safety (strictly speaking, there is no so-called "food grade", "food grade" is just a common name), which can be 410 stainless steel, or other grades of stainless steel.

410 is an ordinary martensitic stainless steel, a long time ago, when China did not have a national standard for food safety, belongs to the stainless steel material recommended by the state for the manufacture of Kaixiao kitchen knives and food machinery.Because the qualified products of this material should not carry "poison".

410 stainless steel 304 stainless steel difference

1. Different ingredients

410 stainless steel includes 0.15% carbon, 13% chromium, C≤0.15, Si≤1.00, Mn≤1.00, P≤0.035, S≤0.030, Cr=11.50~13.50.

The most important elements in 304 are Ni and Cr, but they are not limited to these two elements.The common judgment situation in the industry believes that as long as the Ni content is greater than 8% and the Cr content is greater than 18%, it can be considered 304 stainless steel.

2. Different physical properties

High strength 410 stainless steel; superb machinability; hardening occurs after heat treatment;Not appropriate for corrosive or hostile situations is magnetic.304 stainless steel, often known as 18/8 stainless steel in the business, has a density of 7.93 g/cm3.800°C high temperature resistance, good processing abilities, and high toughness traits.

3. Different marking methods

Ferritic and martensitic stainless steels are 400 series, such as 405,410,443, etc.

Austenitic stainless steels are marked with the 200 and 300 series numbers, for example, some more common austenitic stainless steels are marked with 201, 304, 316, and 310.Among the marking methods on the market are 06Cr19Ni10 and SUS304, of which 06Cr19Ni10 generally indicates national standard production, 304 generally indicates ASTM standard production, and SUS304 indicates daily standard production.
