Star Trading is a specialist in steel castings. Unlike other types of iron, steel casting is more complex, requires more expertise, know-how and specific equipment. We have all this at Star Trading. We now operate three locations with modern and functional infrastructure that enables first-class production.
While simple cast iron grades can be cast from around 1140°, steel must be heated to around 1600°. The higher temperatures in turn require more complex melting technology, from template manufacture to melting furnaces and finishing. Compared with iron castings, the finished castings are more brittle and often require heat treatment. High-alloy steel castings (e.g., extremely heat-resistant materials) are mainly quenched and tempered with chromium, nickel, molybdenum, vanadium, or tungsten. This results in high heat resistance combined with low wear. Another characteristic of cast steel is its shrinkage of 2%, which is twice as high as that of other cast iron grades. In our foundry, we use two production methods in mold making: lost wax and croning.
In addition to steel castings, we also supply a wide variety of grey iron castings. These are produced by our partners under the guidance of our casting engineers and are then delivered as blanks to our foundry, where they undergo any necessary machining based on quality control.
