Heat-resistant steel castings


Cast steel production: properties and composition


Cast steel is an iron alloy with a maximum carbon content of about 0.75%. Steel castings are solid metal objects produced by filling the voids in the mold with liquid steel. They have many of the same carbon steel and alloy steel, which can be produced as forged metals. The mechanical properties of cast steel are generally lower than that of forged steel, but the chemical composition is the same. Cast steel can form complex shapes in fewer steps, which makes up for this disadvantage.


Process precision Casting, other process can be customized.
Material Alloy steels, Carbon Steel , Stainless steel, Malleable iron , Grey iron, Ductile iron Aluminum, Bronze etc.
Unit Weight 0.1kg-100kg
Finish Plain,Nickel Plating , Chrome Plating or Polishing
Application Automotive ,Mining, Railway, Construction equipment,Mining etc
Quality Control CMM, Projection Machine, spectrometer, Hardness tester, Tensile tester etc.
Certificate ISO 9001:2008


Cast steel performance


Cast steel can produce a variety of properties. The physical properties of cast steel change significantly due to chemical composition and heat treatment. They are selected to match the performance requirements of the intended application.



The ability of the material to wear. The carbon content determines the maximum hardness or hardenability available in the steel.

The force required to deform the material. Higher carbon content and hardness result in steel with higher strength.

Metal in

The ability to deform under tensile stress. The carbon content is lower and the hardness is lower, resulting in higher ductility of the steel.

The ability to withstand pressure. Increased ductility is usually associated with better toughness. Toughness can be adjusted by adding alloy metal and heat treatment.


Material friction and use resistance. Cast steel has similar wear resistance to forged steel of similar composition. Adding alloying elements, such as silicon and chromium, can increase wear resistance.


Corrosion materials resist oxidation and rust resistance. The corrosion resistance of cast steel is similar to that of forged steel. High alloy steels with high chromium and nickel content have a high degree of oxidation resistance.


Steel castings are processed (cutting, grinding or drilling) to remove material, which makes it easy to change the shape. Workability is affected by hardness, strength, thermal conductivity and thermal expansion.


The ability to weld steel castings without defects. Weldability mainly depends on the chemical composition and heat treatment of steel castings.
High temperature characteristics

Steels operating at higher than ambient temperature are affected by reduced mechanical properties and early failure due to oxidation, hydrogen damage, sulfite scaling, and cemented carbide instability.

Low temperature characteristics

The toughness of steel is severely reduced at low temperatures. Alloying and special heat treatment can improve the ability of castings to withstand loads and stresses.


Precision investment casting in different industries


The lost wax method is very suitable for the production of large and medium-sized series of investment castings. These castings can be applied to various industries, thus expanding the scope of the compass hardware industry. Compass hardware customers operate in the following industries:



For well-known car manufacturers, Compass Hardware provides precision investment castings for engines, body engineering, gearboxes, and brake and fuel systems. Some examples of products delivered by Compass Hardware are: rocker arm (engine), fuel pump (engine), and shift cylinder (gear box).


Medicine and food

In the pharmaceutical and food industries, Compass Hardware provides a variety of high-quality components. Low roughness values, precise tolerances and the availability of special steel alloys are particularly decisive in this industry. Especially in the food industry, low roughness values ​​are essential to ensure that bacterial growth does not occur when the surface is too rough. In addition, most precision castings are made of stainless steel to avoid the risk of corrosion (rust) and to ensure that the castings remain hygienic after contact with water. Examples of precision investment castings provided by Compass Hardware include: impellers of industrial pumps, ball valves, and valve housings of paint mixers.



Compass Hardware's castings delivered to its petrochemical industry customers include rotors and stators used in drilling systems, or burner heads installed on gas burners. The accuracy and sustainability of these precision castings are usually the decisive factors in choosing the lost wax precision castings.


Process technology

In precision investment casting, compass hardware is a key player in the processing industry. Many components of compass hardware have been developed, usually cast into special alloys. These special alloys are used because these parts are usually used in corrosive (hostile) environments, environments with large temperature differences, or products that require extremely high toughness, strength, or lightness. Some examples of products provided by Compass Hardware include: synchronous gearboxes for hydraulic systems and grid plates for filter systems.
