  • What is 400 Series Stainless Steel?

Composition and Key Properties of 400 Series Stainless Steel

The all-rounder of industry – 400 series stainless steel. This material is more than just a metal, it’s an engineering marvel. 400 series stainless steel is made up primarily of iron, chromium and a small amount of carbon. This combination gives it exceptional strength and corrosion resistance, as well as magnetic properties, making it the perfect all-rounder in the metal world.


  • Maintenance and Longevity of 400 Series Stainless Steel Products

After purchasing 400 series stainless steel products, the factory does need to perform regular maintenance to ensure the long-term performance and life of the products.

①Regular cleaning

Frequency: It is recommended to perform a comprehensive cleaning once a month.

Method: Use mild detergent and warm water for cleaning, and avoid using detergents containing chlorine or other strong acids and alkalis.

Tools: Use a soft cloth or sponge, and avoid using steel wool or other hard cleaning tools to prevent scratching the surface.

②Surface inspection

Frequency: Perform a detailed inspection once a quarter.

Content: Check the stainless steel surface for scratches, corrosion spots or other damage.

Treatment: Deal with problems in a timely manner, and minor scratches can be repaired with stainless steel special polish.

③Environmental control

Measures: Try to avoid exposing stainless steel products to high salinity or high humidity environments, which may accelerate corrosion.

Storage: When storing stainless steel products, ensure that they are dry and away from corrosive substances, and use protective covers or packaging materials for protection.

④Lubrication and protection

Frequency: Lubricate and protect once every six months.

Method: Use a special protective agent or lubricant for stainless steel, apply it to key parts to prevent rust and wear.

⑤Professional maintenance

Frequency: Professional maintenance once a year.

Content: Ask professional technicians to perform a comprehensive inspection and maintenance to ensure that all parts are in optimal condition.

  • Is 400 Series Stainless Steel Magnetic?

Of course, 400 series stainless steel is magnetic! Imagine holding a 400 series stainless steel knife in your kitchen and suddenly finding that it attracts the magnet on your refrigerator. It's a bit like discovering a little magic, isn't it? In fact, it's not magic, but because the internal structure of 400 series stainless steel contains ferrite or martensite, which makes it magnetic.
