Weldingseam structure: Observe the structural composition of the welding area, including the grain structure and phase composition of the base material, the deposited layer, and the fusion line, etc.

Properties: It features high strength, hardness and wear resistance, and is easy to process and weld. Testing items: hardness test, tensile test, impact test, metallographic analysis, chemical composition analysis, etc.

Stress corrosion refers to the phenomenon where a material undergoes corrosion in a corrosive medium under the influence of stress. Based on different corrosion mechanisms and manifestations

The composition of metal materials is the main factor determining their properties. Understanding the composition and properties of metals enables better application of materials in products. Based on the trade-offs of the adaptability of various metal material detection methods to different materials

Various mechanical performance criteria of metal materials are determined through different mechanical tests. The properties displayed by metals under the action of force, which are related to elasticity and non-elasticity as well as related to stress-strain, all belong to the mechanical properties of metals.

Microstructure testing is one of the main methods for studying the internal structure and defects of metals and their alloys. It is also the most basic experimental technique for studying the microstructure of metal materials.

In the field of materials science, metal material tensile testing is a crucial experimental technique. It not only provides us with important data on the mechanical properties of metal materials, but also helps us understand the deformation and fracture behavior of materials under force.

In the field of materials science and engineering, the impact toughness of metal materials is an important indicator for measuring their ability to resist impact loads without brittle fracture.
