Morphology and Mechanical Properties of Pearlite
Pearlite is a mechanical mixture of ferrite and cementite. According to the morphology of cementite, pearlite can be classified into lamellar pearlite and granular pearlite. Lamellar Pearlite Lamellar pearlite consists of alternating layers of ferrite and cementit...Read more -
Effect of Carbon Content on the Process Properties of Iron–Carbon Alloys
Machinability The machinability of metallic materials is a highly complex issue, generally evaluated from aspects such as allowable cutting speed, cutting force, and surface roughness. Factors including the material’s chemical composition, hardness, toughness, thermal co...Read more -
Hot Working of Metals
Hot Working and Cold Working of Metals Plastic deformation processing is a method of forming and modifying metals by applying pressure. However, when plastic deformation is performed at room temperature, work hardening occurs, which increases the resistance to def...Read more -
Long-Term High-Temperature and Endurance Performance Measurement of Cast Steel
The following two measurement methods are applicable to stainless steel castings, alloy steel castings, and carbon steel castings. Endurance performance test The endurance performance test is to determine the strength of a material that does not break at a given temperat...Read more -
Key Process Elements of Steel Casting Heat Treatment
The as-cast microstructure of steel castings depends on their chemical composition and solidification and crystallization processes. These typically exhibit severe dendritic segregation, extremely uneven microstructure, coarse grains, and a Widmanstätten (or reticular) s...Read more -
Impact Testing of Steel Castings
Impact testing is applicable to castings of various materials, such as stainless steel castings, alloy steel castings, and carbon steel castings. Impact testing is a dynamic mechanical test in which a notched specimen of a specific shape is pulled, twisted, or bent to ra...Read more -
Application of Casting Process Equipment – Core Boxes and Flasks
Core Boxes In foundry production, except for a few simple castings that do not require cores to form the internal cavities or holes, most castings use cores to form their inner structures. A core box is the necessary mold for manufacturing cores. Its dimensional accuracy...Read more -
Penetrant Testing of Steel Castings
Penetrant testing is applicable to stainless steel castings, alloy steel castings, carbon steel castings and other steel castings. 1. Basic Principles This is a detection method that uses the good penetration and capillary action of colored penetrants or fluorescent pene...Read more -
Application of Casting Process Equipment — Patterns and Pattern Plates
Patterns A pattern is one of the essential tools in the molding process. Its function is to form the mold cavity, and therefore, the pattern directly determines the shape and dimensional accuracy of the casting. To ensure casting quality and improve molding productivity,...Read more -
Heat Treatment of Corrosion-Resistant Stainless Steel Castings
1. Heat Treatment of Martensitic Corrosion-Resistant Stainless Steel Castings Martensitic corrosion-resistant stainless steel cast steel contains 13% chromium by mass and a high carbon content, resulting in excellent hardenability. After proper heat treatment, it exhibi...Read more -
Heat Treatment of Wear-Resistant Steel Castings
1. Solution Heat Treatment of Wear-Resistant High-Manganese Steel Castings – Water Toughening Wear-resistant high-manganese steel has a large amount of precipitated carbides in its as-cast structure, resulting in low toughness and prone to fracture during use. The primar...Read more -
Repair of Casting Defects
stings with defects are not necessarily scrap. With necessary repairs to remove the defects, as long as the technical requirements of the casting can be met, most repaired castings can still be used as finished products. The purpose of repairing casting defects is to avo...Read more
