Carbon Steel Casting
What is carbon steel casting？
Cast steel parts are parts made of cast steel with similar properties to cast iron, but with better strength than cast iron.
Carbon steel is an iron-carbon alloy with a carbon content of 0.0218% to 2.11%. It is also called carbon steel. Carbon steel castings (also known as carbon steel fine castings) are metal castings consisting mainly of iron and carbon elements. Carbon steel is one of the main materials in the current steel casting industry. It has the advantages of low cost, high wear resistance, easy preparation, and can be heat treated to improve its strength, ductility, and workability.
Classification of carbon steel
Low carbon steel (<0.20% C)
Also known as soft steel due to its low strength, low hardness, and softness.
Medium carbon steel (0.20 to 0.50% C)
It is the most widely used material in various applications at medium strength levels. In addition to being used as a construction material, it is also widely used in the manufacture of various mechanical parts.
High carbon steel (> 0.50% C)
After proper heat treatment or cold drawing and hardening, high carbon steel has the advantages of high strength, high hardness, high elasticity, and not being easy to deform.
Advantages of carbon steel castings
Compared to other steels, carbon steel is the most used and is easily obtained by casting. Carbon steels are heat treated to obtain higher hardness and better wear resistance.
It is very moderately hard in the annealed condition and has good machinability. Carbon steel is a very common raw material, easy to obtain, and relatively inexpensive to produce.
Carbon Steel Casting Process
There are currently two processes for carbon steel castings: water-glass casting or silica-sol casting
Water-glass is added to the molding material (usually called silica sand) in a certain proportion and made into “water-glass sand” by mixing, rolling, and blending, and then blown into the mold and sandbox containing carbon dioxide gas, carbon dioxide, and water. The silica gel is formed through a chemical reaction that hardens the water-glass sand and is completed by the process of lifting the mold, closing the box, and pouring.
Silica sol investment casting: This is a lost wax casting method. A mold is first made according to the shape of the silica-sol casting and the wax mold is placed in a solution made of silica-sol and quartz sand. The wax mold will be covered with a layer of material and then solidified. After repeated soaking and curing, the mold shell is basically formed. Finally, it will be dewaxed and cast.
Application of carbon steel castings
General mechanical parts: gears, connecting rods, engine covers, etc.
