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 -
Heat Treatment of Carbon Steel Castings and Medium- and Low-Alloy Steel Castings
Heat Treatment of Carbon Steel Castings Common heat treatment methods for carbon steel castings include annealing, normalizing, or normalizing + tempering. Normalized cast steel exhibits slightly higher mechanical properties than annealed steel. Due to the greater degree...Read more -
Factors Affecting Cast Steel Properties
This article focuses on the three main factors affecting the properties of steel castings. The Impact of Common Impurity Elements in Steel The Impact of Common Elements Common impurity elements in steel include phosphorus (P), sulfur (S), hydrogen (H), nitrogen (N), and ...Read more -
Design of Cores
The core is an important part of the mold. Its function is to form the inner cavity and holes of the casting, to shape undercuts, and to produce parts of the mold that have special requirements. A core should meet the following requirements: the shape, dimensions, and po...Read more -
Characteristics and Applications of Heat-Resistant Steel Bars
5Cr21Mn9N14N (UNS S63008) Suitable for manufacturing exhaust valves for gasoline and diesel engines, where high-temperature strength is the primary requirement. 2Cr21Ni12N (UNS S63017) Suitable for manufacturing exhaust valves for gasoline and diesel engines, where oxida...Read more -
Application of Chills
A chill is one of the most commonly used metal blocks for controlling the solidification of castings. Chills can be used for all types of casting alloys, but they are most widely applied in steel castings. The main functions of chills are as follows: 1. Used together wit...Read more
