Explanation of stainless steel terms

Ductility

Measure the maximum deformation that a stainless steel plate can withstand before failure.

Edge rolling (edge adjustment)

To facilitate customer operation, all burrs should be removed when rolling stainless steel bars to ensure smooth edges.

Elastic

When the stainless steel plate is bent, the metal is in a state of tension towards the outside of the bending, and the metal is compressed towards the inside. If the applied bending force is not sufficient to cause permanent plastic flow on the inner or outer surface, the metal will elastically return to its original shape. Stainless steel has a greater elastic rebound than soft Steel.

Elongation

The measurement of ductility based on the tensile behavior of a standard tensile specimen at a given length at the time of fracture, usually based on the original 2-inch length.

Embrittlement

The loss of ductility caused by chemical treatment or physical changes in materials.

Erosion corrosion

The interaction between corrosive materials and stainless steel leads to material corrosion and accelerated corrosion behavior.

Squeeze

Formed stainless steel sheets are made by forcing patterns, rods, or rods through appropriately shaped molds.

General corrosion

General corrosion refers to the phenomenon of corrosion occurring in a relatively uniform manner on the entire surface of a metal. Normally, stainless steel plates do not exhibit general corrosion.

Grain size (grain boundary)

Each crystal unit containing an aggregation structure with unchanged crystal orientation. The grain boundary is the place where these individual crystal units meet.

Grind

Refers to a metal removal operation similar to rapid grinding, where protrusions on the metal surface are removed by wear.

Stress fatigue

Stress fatigue refers to the situation where a stainless steel plate undergoes ultimate material fracture due to continuous or repeated application of pressure. Typically, the pressure applied to the material should be lower than its tensile strength.

Ferrite

Ferritic stainless steel is a type of magnetic stainless steel with a low carbon content, usually containing chromium as the main alloying element, with a content of about 13% -17%. This type of stainless steel is the second largest application of stainless steel. Ferritic stainless steel is commonly used in automotive decoration and exhaust systems, hot water tanks, and indoor building decoration.
