hydrogen cracking
Hydrogen induced cracking (HIC) is a type of stress corrosion cracking (SCC) that occurs in metals and alloys exposed to hydrogen at high pressure and low temperatures. HIC is often observed in components used for oil and gas production, such as pipelines and pressure vessels, but can occur in any......
Plate Forming Mesh Measurement Technology
Form Grids Measurement Technology
Form grid measurement is a nondestructive testing (NDT) technique used to measure the geometric profile of components with complex shapes. It employs the use of a form grid composed of a series of equidistant points distributed over a defined area. The forms of t......
Stress corrosion cracking and hydrogen embrittlement
Stress Corrosion Cracking and Hydrogen Embrittlement
Stress corrosion cracking (SCC) and hydrogen embrittlement are two of the most significant forms of corrosion failure in many industrial and natural settings. Both involve the application of an external force, typically in the form of mechanica......
Radiographic inspection
Introduction
Ray inspection is a nondestructive testing technique used to detect irregularities in materials and components. Ray inspection enables the detection of surface and internal defects in materials without damaging them. It is widely used for quality assurance and quality control for man......
Magnetic particle inspection
Magnetic Particle Testing
Magnetic particle testing (MPT) is one of the most effective non-destructive testing methods used to detect surface and near surface discontinuities in ferromagnetic materials such as iron and steel. This non-destructive test involves the introduction of a magnetic fiel......

Corrosion Properties of 1Cr17Ni6Mn5N (AISI201) Austenitic Stainless Steel
Introduction
The 1Cr17Ni5Mn6N (AISI201) austenitic stainless steel is a relatively new member of the chromium-nickel family of stainless steels. It belongs to the group of ferrite-austenite duplex stainless steels that con......
ASTM A193M-1998a Alloy steel and stainless steel bolting materials for high temperature service
ASTM A193M-1998a Specification for Alloy Steel and Stainless Steel Bolting Materials for High Temperature Service
ASTM A193M-1998a is a material specification developed by the American Society for Testing and Materials (ASTM). It specifies the requirements for alloy steel and stainless steel bolt......
Characteristics and causes of internal cracks
Introduction
Internal cracks are important physical defects in metal materials. It can cause metal materials to lose their mechanical properties, thus losing their large performance and service life. At present, the identification of internal cracks mostly relies on conventional non-destructive te......
Classification and conversion relationship of metal hardness
Classification and Conversion Relationship of Metal Hardness
Metal hardness is a key property in metal materials. It is used to determine the ability of a material to resist plastic deformation when it is subjected to mechanical loading, and to measure the materials strength, rigidity and wear re......
