What is stainless steel?

Stainless steel is an iron and chromium alloy. While stainless must contain at least 10.5% chromium, The components and ratios will vary based on the grade requested and the intended use of the steel. The steel also contains varied amounts of other elements such as Carbon, Silicon and Manganese. Other elements can be added to increase corrosion resistance (Nickel) and formability (Molybdenum).

Applications include food handling/processing, medical instruments, hardware, appliances, and structural/architectural uses.

The Three Primary Types of Stainless Steel

While there are thousands of different types of stainless steel alloy that can be produced, most alloys will fall into one of the following three categories.

Austenitic stainless steel

There are two main characteristics of this type of stainless steel. First, there is a lot of chromium included during the production of austenitic stainless steel. Items produced with this material are more corrosion-resistant. Second, these items tend to be non-magnetic, although they can become magnetic with a cold forming process. These are the most common types of stainless steel alloys.

Ferritic Stainless Steel

This type of stainless steel is the second most common type of alloy and is also magnetic. Items produced with this alloy can be hardened through cold forming and also tend to be less expensive than other types due to the lower nickel content.

Martensitic Stainless Steel

This material is the least common type of stainless steel alloy. Martensitic stainless steel is used in applications where high tensile strength is needed or a lot of impact resistance. In many cases, this material is also combined with a protective polymer coating to improve corrosion-resistance

Advantage of Stainless steel

  • Beautiful surface and diversified use possibilities
  • Good corrosion resistance, longer durable than ordinary steel.
  • High strength
  • High temperature oxidation resistance and high strength, can resist fire
  • Processing at room temperature, easy to plastic processing
  • Because there is no need to surface treatment, so simple, simple maintenance
  • Clean, good finish
  • Good welding performance
