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 -
Heat Treatment of Wear (Abrasion) Resistant Steel Castings
Wear-resistant (or abrasion-resistant) cast steel refers to cast steel with good wear resistance. According to chemical composition, it is divided into non-alloy, low-alloy and alloy wear-resistant cast steel. There are many types of wear-resistant steel, which can be ro...Read more -
Heat Treatment of Medium and Low Alloy Steel Castings
Medium and low alloy steels are a big group of alloy steels with alloying elements (mainly chemical elements such as silicon, manganese, chromium, molybdenum, nickel, copper and vanadium) content of less than 8%. Medium and low alloy steel castings have good hardenabilit...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 -
General Information of Heat Treatment for Steel Castings
The heat treatment of steel castings is based on the Fe-Fe3C phase diagram to control the microstructure of the steel castings to achieve the required performance. Heat treatment is one of the important processes in the production of steel castings. The quality and effec...Read more -
No-Bake Sand Casting Process
Sand molds used in sand casting are classified into three types: clay green sand, clay dry sand, and chemically hardened sand according to the binder used in the sand and the way it builds its strength. No-bake sand is foundry sand th...Read more -
Normalization Heat Treatment for Steel Castings
Normalizing, also known as normalization, is to heat the workpiece to Ac3 (Ac refers to the final temperature at which all free ferrite is transformed into austenite during heating, generally from 727°C to 912°C) or Acm (Acm is In actual heating, the critical temperature...Read more -
Austenitic Stainless Steel
Austenitic stainless steel refers to stainless steel with an austenitic structure at room temperature. Austenitic stainless steel is one of the five classes of stainless steel by crystalline structure (along with ferritic, martensitic, duplex and precipitation hardened)....Read more -
Gray Cast Iron Mechanical Properties
Gray iron, or grey cast iron, is a type of cast iron that has a graphite microstructure. It is named after the gray color of the fracture it forms. The gray cast iron is used for custom grey iron castings where the stiffness of the component is more important than its te...Read more
