Ferritic Stainless Steel Casting
Ferritic stainless steel refers to stainless steel with body-centered cubic ferrite as the matrix structure at high temperature and normal temperature. Ferritic stainless steel has iron and chromium as the main elements, generally does not contain nickel, and some contai...Read more -
Magnetic Particle Inspection of Casting Internal Defects
Magnetic particle inspection is a detection method that uses the properties of ferromagnetic materials (such as steel, iron, cobalt, nickel, etc.) to be magnetized. When the metal casting is strongly magnetized by the magnetic field, if there is a defect perpendicular to...Read more -
Radiographic Inspection of Castings
Radiographic Inspection of Castings 1. The basic principle of radiography In the process of penetrating the casting, X-ray or γ-ray interacts with the material, and its intensity is attenuated by absorption and scattering. Images with varying degrees of blackness ...Read more -
304 Stainless Steel
304 stainless steel is a grade of stainless steel produced according to the American ASTM standard. Among all stainless steel materials, 304 stainless steel is almost the most common grade. The density of 304 stainless steel is 7.93 g/cm³. The professional name of 304 st...Read more -
China Material Grades for Grey Iron and Ductile Iron
Cast iron is an iron-carbon alloy with a mass fraction of carbon greater than 2.11%. Cast iron is obtained by remelting pig iron in the furnace, adding ferroalloy, scrap steel, and returning to the furnace to adjust the composition. Grey cast iron and ductile iron are th...Read more -
Centrifugal Impeller Pump
A pump is a mechanical device that conveys or pressurizes a fluid. It transfers the original mechanical energy or other external energy to the liquid to increase the liquid energy, thereby completing the liquid transportation. The pump is mainly used to transport liquids...Read more -
What Is Industrial Caster?
A caster is a device consisting of a single or multiple wheels, which may be the equipment or platform mounted on it to move. The casters are passively driven. Casters usually consist of wheels and brackets, sometimes with brake parts, etc. Casters are a general term, in...Read more -
Heat Treatment of Austenitic Stainless Steel Castings
The as-cast structure of austenitic stainless steel castings is austenite + carbide or austenite + ferrite. Heat treatment can improve the corrosion resistance of austenitic stainless steel castings. Equivalent Grade of Austenitic Stainless Steel AISI ...Read more -
Heat Treatment of Martensitic Stainless Steel Castings
Martensitic stainless steel refers to a type of stainless steel whose microstructure is mainly martensite. The chromium content of martensitic stainless steel is in the range of 12% - 18%, and its main alloying elements are iron, chromium, nickel and carbon. Martensitic ...Read more -
The Heat Treatment of Carbon Steel Castings
The heat treatment methods usually used for carbon steel castings are: annealing, normalizing or normalizing + tempering. The influence of these three heat treatment methods on the mechanical properties of cast carbon steel is shown in the figure below. The ...Read more -
Chemical heat treatment of steel castings
The chemical heat treatment of steel castings refers to placing the castings in an active medium at a certain temperature for heat preservation, so that one or several chemical elements can penetrate the surface. Chemical heat treatment can change the chemical compositio...Read more -
Surface Heat Treatment of Steel Castings
Surface heat treatment refers to the process of heat-treating only the surface layer of steel castings. Surface heat treatment can also obtain the required metallographic structure and mechanical properties. Commonly used surface heat treatment methods are: induction hea...Read more
