DIN 1623-1:1983 is a German industrial standard concerning the technical conditions for the supply of cold rolled strips (plates) of low carbon steel for cold forming. The standard specifies in detail the size, shape tolerance, chemical composition, mechanical properties, surface quality and delivery status requirements of cold-rolled low carbon steel strips (steel plates) to ensure that the steel products produced can meet the specific needs of use.
DIN 1623-1:1983 Features
Cold rolling process: The steel is cold rolled and has high dimensional accuracy and surface finish.
Low carbon content: Due to the low carbon content, steel usually has good plasticity and toughness, and is easy to process and form.
Multiple grades: The standard may contain multiple grades (such as St12, St13, St14, etc.), each grade may differ in chemical composition and mechanical properties to meet different application requirements.
Strict quality control: The standard specifies strict inspection methods and acceptance standards to ensure the consistency and reliability of product quality.
DIN 1623-1:1983 Chemical composition
The chemical composition of steel in DIN 1623-1:1983 varies from grade to grade, but usually includes elements such as iron (Fe), carbon (C), silicon (Si), manganese (Mn), phosphorus (P) and sulfur (S). The specific chemical composition should be confirmed according to the specific brand and product specifications. For example, grades such as St12, St13 and St14 may differ slightly in carbon content, affecting their mechanical properties and processability.
DIN 1623-1:1983 Scope of application
Steels specified in DIN 1623-1:1983 are used in a wide range of applications due to their excellent properties, including but not limited to:
Automotive industry: Used to manufacture automotive shell, internal structural parts, chassis parts, etc., requiring materials with high strength and good formability.
Home appliance industry: In the manufacture of home appliances such as refrigerators, washing machines and air conditioners, these steels are used to make internal parts and housings.
Construction industry: In building structures, these steels can be used to manufacture structural parts such as beams and columns, or used to manufacture metal products for construction.
Mechanical manufacturing: In the field of mechanical manufacturing, these steels are used in the manufacture of various mechanical parts and components, such as gears, bearings, transmission parts, etc.
