The most important reason why manufacturers do not use stainless steel to build cars is that it is expensive. If it is purely for anti-corrosion, it is completely unnecessary.

Do you know what elements stainless steel is composed of? All reflect the functions? There are about 19 species.

Welding can realize metal connection, and the core lies in the interaction between "heat source" and "molten pool".

In the field of stainless steel welding, balanced phase diagrams are the core theoretical tools for interpreting phase change laws, predicting microstructures, and optimizing process parameters.

Iron-carbon metallographic structure diagram, as the name suggests, is a graph describing the internal structure and phase transition process of iron-carbon alloys under different temperatures and carbon content conditions.

Welding process evaluation (WPQ) and welding process regulations (WPS) are the two core links in the welding quality control system.

In order to obtain the required mechanical properties, and to obtain its inherent, good corrosion resistance and suitable high temperature strength, heat treatment is an extremely important process and production link in the production of stainless steel workpieces.

Fusion welding refers to the process of melting two pieces of metals through high temperature or other means, mixing the melt and then cooling and crystallizing to firmly connect the two pieces of metals together.

Hardness is an important performance indicator for measuring the hardness and hardness of metal materials. It indicates the ability of the material to resist locally pressing hard objects into its surface. It generally reflects the ability of plastic deformation, indentation or scratches. Generally, the higher the hardness, the better the wear resistance.

Steel, also known as iron-carbon alloy, is an alloy composed of iron (Fe) and carbon (C), silicon (Si), manganese (Mn), phosphorus (P), sulfur (S) and other small amounts of elements (Cr, V, etc.).

Welding process evaluation is a key link in ensuring welding quality. It provides a reliable basis for actual welding production through systematic verification of welding process.

Stainless steel weld X-ray flaw detection technology is a non-destructive detection method widely used in the industrial field, mainly used to detect internal defects of welds
