Steel
Cast steel is used for components that must withstand high loads, impact, wear, or elevated temperatures. Such cast steel parts are in demand in mechanical engineering, metallurgy, energy technology, and other industrial sectors where strength, precise geometry, and subsequent machining are important.
For each project, the appropriate cast steel material is selected based on the actual operating conditions. Key factors include load, temperature, wear, the working environment, and the requirements for the finished component. If necessary, heat-resistant cast steel can also be used when the structure is continuously subjected to thermal stress.
Steel Grades for the Manufacture of Cast Steel Parts
Various grades of steel are used in the manufacture of cast steel components—depending on the conditions under which the component will later operate. The decisive factors are load, temperature, wear, impact stress, and the requirements for the finished part.
Consequently, the appropriate cast steel material cannot be selected in general terms but must be chosen specifically for a particular application. This ensures that the finished cast component possesses the necessary mechanical properties, remains machinable, and can be reliably used in machines, systems, or other industrial assemblies.

Advantages of Custom Cast Steel
-
High strength
Cast steel is used in applications where a component is subjected to continuous stress, must withstand impact loads, and is required to retain its shape even under difficult operating conditions.
-
Resistance to Wear and Temperature
Cast steel parts are suitable for assemblies in which the material is exposed to friction, heat, or varying operating conditions. Depending on the application, heat-resistant cast steel or wear-resistant cast steel can be used.
-
Good options for further processing
After casting, the component can be machined. This allows for the production of precise dimensions, mating surfaces, holes, and prepared working surfaces in accordance with the drawing.

Frequently Asked Questions about Steel Casting
Yes. In such projects, the material is selected based on operating conditions—impact, wear, temperature, environment, strength requirements, and subsequent machining—rather than the part’s name. For instance, GS-52 might be considered for certain housing and loaded parts if the task requires clear material mechanics and predictable operational behavior.
Yes. If a project is tied to international requirements, steel casting to DIN 1681 or steel casting to EN 10293 can be incorporated into the calculation from the outset—depending on which standard is more convenient for the customer regarding coordination and acceptance.
Yes. For such tasks, not only the shape of the part but also the alloy’s resistance to the actual operating environment is typically crucial. In these projects, GX8CrNi12 can be applied if the customer requires a stainless steel casting with clear properties for a specific assembly.
Both formats are possible. If a single part is needed for repair, the order can be launched individually. If it involves a recurring nomenclature, it is more convenient to manage the project as a steel foundry under an agreed supply program—with clear logic regarding materials, deadlines, and batch repeatability.
Yes. If a full set of design documentation is unavailable, the part itself, a sketch, or a technical description can be submitted for production. Following an evaluation of the geometry and operating conditions, it becomes clear which steel grade is suitable, which standard is logical to apply, and how best to proceed with manufacturing.

Custom Steel Casting for Industrial Equipment
When an enterprise requires a part designed for a specific load rather than a standard blank, steel casting is typically chosen. This format is suitable for housing assemblies, plates, supports, covers, transition elements, and parts that subsequently undergo mechanical machining and operate within equipment. In such orders, it is important not merely to cast the metal into a shape, but to immediately understand the environment in which the part will operate, the load it will withstand, and the service life margin required by the customer.
The Western Foundry Group, comprising Promlit Plant LLC and Gorstal Plant LLC, accepts orders for castings based on drawings, 3D models, samples, and technical specifications. This is a convenient format for the customer: it is possible to submit either a single part for repair or a series for scheduled deliveries, without unnecessarily fragmenting the project among different contractors.
Where Steel Castings Are Applied
In practice, metal casting is ordered when rolled products, welded blanks, or standard finished parts do not solve the problem. This applies to assemblies for mechanical engineering, the power sector, transport equipment, metallurgy, and production lines, where precise geometry, strength, and the ability to adapt the product to specific operating conditions are crucial.
The items most frequently submitted for production include:
- Housing parts and covers;
- Plates, bases, and supports;
- Flanges and transition elements;
- Pump and gearbox equipment components;
- Blanks for mechanical machining;
- Non-standard items based on custom drawings.
Which Steel Grades and Groups Are Used
The selection of an alloy is always based on operating conditions, not just the “name of the part”. That is precisely why the steel casting material is coordinated prior to launching the order. The exact same housing can be cast from different grades—depending on temperature, pressure, corrosive environment, impact load, and service life requirements.
To quickly grasp the selection logic, the main groups can be summarized as follows:
| Steel Group | Where It Is Typically Applied |
| Carbon | Housing parts, bases, supports |
| Alloyed | Loaded assemblies, wear parts |
| Stainless | Pumps, valves, chemical equipment |
| Heat-resistant | Furnace, power, and metallurgical assemblies |
Stainless, Heat-Resistant, and Wear-Resistant Casting
If a part operates in a humid or aggressive environment, stainless steel casting is usually considered for the calculation. Such castings are in high demand for pump assemblies, valves, covers, flanges, and other parts where standard steel quickly loses its service life. Here, corrosion resistance, geometric stability, and the capability for subsequent machining come to the forefront.
For assemblies operating under heating and thermal cycles, heat-resistant steel casting is utilized. In these projects, it is vital not only to maintain the part’s shape but also to preserve the metal’s properties at high temperatures.
If the primary objective is resistance to abrasion and heavy operational loads, wear-resistant steel casting can be incorporated into the project. This is particularly relevant for parts continuously subjected to friction, impact, or abrasive wear.
Manufacturing and Pricing Factors
For a number of projects, sand casting is applied—this is a convenient manufacturing method when flexibility in geometry is needed, allowing work with varying part masses and the launching of both single items and series.
For the customer, what matters is not an abstract price list, but the final cost of a specific part. Prices for steel casting are influenced by the casting’s mass, shape complexity, selected steel grade, batch size, precision requirements, mechanical machining, and manufacturing lead times. Serial items generally offer a more predictable unit cost, whereas single items are more heavily dependent on tooling preparation and project complexity.
What is Needed for an Estimate
To receive a quick calculation, it is usually sufficient to provide:
- A drawing;
- A 3D model;
- A sample;
- A specification;
- A brief description of operating conditions.
After this, we can substantively discuss the steel grade, molding method, scope of mechanical machining, and manufacturing lead time.
