Categories, types, grades of stainless steel

The generally accepted division of stainless steel grades into series, categories, types, subtypes, kinds and subspecies in accordance with the purpose, application, chemical composition, microstructure, chemical, physical, technological and other properties of stainless steel. Each series, category and type of stainless steel is divided into many grades, each of which has its own unique chemical composition, physical properties and area of ​​application.

Definition of stainless steel grade: stainless steel grade is designated by a digital-alphabetical code containing information about its chemical composition and structure.

Selecting a stainless steel grade

When choosing a grade of stainless steel or alloy, it is important to consider the following factors:

  1. Service conditions: consider the environment in which the steel will be used and the type of corrosion it may be subject to.
  2. Properties required: determine which properties are important for your application, such as corrosion resistance, strength, ductility, or weldability.
  3. Cost: different grades of stainless steel have different costs.
