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 -
