Stay on track with ductile.
What's more powerful than a locomotive? The rail transport industry still plays a role in the North American logistics landscape, delivering freight from coast to coast. Trains stretch sometimes over a mile long, composed of dozens of railcars that connect and link through complex freight car components. Each coupler connects one car to the next, forming a continuous train and ensuring operational safety and efficiency.
Ductile iron castings are ideally tailored to the rigors of rail transport — tension, compression, friction, and vibration — which come with the starting and slowing momentum of trains weighing thousands of tons. SG iron can match the strength of steel components while offering superior flexible properties, keeping railcars firmly connected but cushioned from shocks and intracar collisions. Let's get the train rolling on a casting exactly suited to your customers' specifications.
WHY DUCTILE IRON castings for freight car components?
Near-net shapes
Sand casting and vertical in-mold inoculation allow Urick to achieve near-net shape for complex components — no cutting or welding necessary. That translates to faster turnaround times.
Replicability
Urick maintains lifetime patterns for our partners, meaning a part you produced through us can be replicated for both the length of your train and the length of our relationship.
Resilience
Austempering allows us to emulate the hardness of forged steel while preserving the elongation and wear resistance properties of ductile iron, all at a reasonable cost.
Safety-Critical Ductile Iron Parts for railroad transport
Urick specializes in the casting of safety-critical parts such as top caps and housings, which are essential components in the rail transport industry. These parts are extremely important, as they play a pivotal role in the overall safety and stability of trains.
Top caps and housings are used together to create sophisticated balancing mechanisms on trains. These structures are crucial for maintaining the stability and alignment of railcars as they traverse vast distances and varied terrains. By ensuring that railcars remain balanced, these components help to prevent derailments such as the catastrophic East Palestine incident.
The Role of Ductile Iron in Safety-Critical Parts
Unlike traditional cast iron, ductile iron contains graphite in the form of nodules, which impart both strength and flexibility to the material. This unique combination allows ductile iron to absorb and dissipate the immense forces exerted on rail components, reducing the risk of fractures and failures.
Our commitment to producing high-quality spheroidal graphite castings means that you can trust our parts to perform under the most demanding conditions. We work closely with OEMS and our value-added service partners to ensure that every part meets the highest ASTM A536 standards of quality and safety, every time.
