Tungsten Carbide (TC) Rings Supplier in India
Kathuria Techmech Pvt. Ltd. supplies precision-engineered tungsten carbide (TC) rings for high-speed wire rod mills, bar mills and steel rolling applications. Available in multiple carbide grades and custom profiles, our rings are selected to meet specific requirements for wear resistance, hardness, dimensional accuracy and operating conditions.
Tungsten Carbide (TC) Rings Supplier in India
Choosing the right tungsten carbide (TC) ring supplier in India involves more than comparing prices. Material grade, dimensional accuracy, application suitability and product life are equally important. An experienced supplier helps you select the appropriate carbide grade, achieve dimensional accuracy and improve ring service life. Although compact in size, tungsten carbide rings play an important role in maintaining dimensional accuracy and operational reliability in industrial machinery. They handle heat, pressure, rubbing, and wear every day.
Think of a TC ring like the sole of a good shoe. A weak sole wears out fast and affects your whole walk. Similarly, a properly selected tungsten carbide ring can deliver longer service life under suitable operating conditions. In the same way, a high-quality tungsten carbide ring protects pumps, rolling mills, compressors, and other machines from early damage.
What Is a Tungsten Carbide Ring?
A tungsten carbide ring is a hard, round industrial part. It is made from tungsten carbide powder mixed with a binder, usually cobalt or nickel. The mixture is pressed into shape and then sintered at high heat. This makes a dense and very hard ring.
TC rings are known for high hardness, strong wear resistance, and good resistance to heat and corrosion. They are commonly used as mechanical seal faces, roll rings, wear rings, guide rings, and cutting or shaping parts. Their hardness and durability make them useful where ordinary steel parts would wear out too soon.
Why Indian Industries Use TC Rings
India has a large base of steel plants, pump makers, chemical units, wire-drawing units, and engineering companies. These industries need parts that can work for long hours without frequent replacement.
A TC ring helps reduce downtime. When a machine stops, production stops too. That means lost time, extra labour, and sometimes urgent repair costs. A good TC ring can keep its shape and surface finish for longer, so the machine runs smoothly for more hours.
For example, in a wire rod rolling mill, the ring faces constant friction and heat. A tungsten carbide roll ring can maintain better dimensional accuracy and reduce the number of roll changes. This improves output and lowers maintenance pressure.
Types of TC Rings We Supply
A reliable Tungsten Carbide (TC) Rings Supplier in India should offer more than one type. Every machine works differently, so one ring cannot fit every need.
- Mechanical seal rings: Used in pumps, compressors, agitators, and fluid-handling machines to control leakage.
- TC roll rings: Used in wire rod mills, bar mills, strip mills, and seamless pipe mills.
- Wear rings: Used where metal parts rub against each other or face abrasive material.
- Guide rings and roller guides: Used in wire drawing and rolling lines to guide material smoothly.
- Custom TC rings: Made as per customer drawings, including special bore sizes, grooves, steps, and finishes.
If you are unsure which type you need, share your machine details, working temperature, fluid type, and old ring drawing. A good supplier will guide you instead of simply selling whatever is in stock.

TC Ring Types and Profiles
Kathuria Techmech, one of the top Tungsten Carbide (TC) Rings Supplier in India, supplies Tungsten Carbide Rings in three standard profile configurations to suit varying groove geometries and rolling pass designs.
TC Rings With Grooves
Tungsten carbide roll rings featuring precision-machined grooves designed for specific rolling pass profiles. These rings are used in wire rod and bar mills to achieve the required product dimensions and surface finish.
TC Rings Without Grooves
Plain tungsten carbide rings with an ungrooved working surface, suitable for applications requiring a smooth contact profile or specific customer-designed configurations.
TC Rings With Notched Grooves
Tungsten carbide roll rings featuring specially designed notched groove configurations. The profile can be selected according to the rolling process, material dimensions and cooling arrangement.
Cooling Arrangement for TC Rings
Correct cooling is critical to maximising the service life of Tungsten Carbide rings. The following parameters apply to traditional high-speed finish rolling applications.
Cooling Water - Key Parameters
- Pressure range: 0.4 – 0.6 MPa
- Spray angle: Radial, 15–30° to roller rotation direction
- Nozzle distance: 150–250 mm from carbide ring surface
- Water flow from the hot exit side: Approx. 30% of total flow
- Stream width: 2× the groove width; no mist or scatter
- Temperature: ≤ 35°C
Water Flow Rate by Groove Width
| Groove Width (mm) | < 12 | 12–24 | 24–36 | 36–50 |
|---|---|---|---|---|
| Flow Rate (m³/stand·hr) | 18 | 20 | 22 | 25 |
Water Volume by Binder Content
| Binder Content (%) | 6 | 10 | 15 | 20 | 25 | 30 |
|---|---|---|---|---|---|---|
| Volume (L / groove mm · min) | 56 | 48 | 40 | 32 | 24 | 16 |
Cooling Water Quality Requirements
Where Are TC Rings Used?
Our Tungsten Carbide Rings are specified by engineers across a wide range of rolling and forming applications that demand high surface hardness and dimensional stability.
How to Choose the Right Supplier
There are many TC ring suppliers in cities such as Delhi, Mumbai, Kolkata, Ahmedabad, Pune, and Faridabad. But the best supplier is the one who understands your application.
Here is what to check before placing an order:
- Material grade: Ask about tungsten carbide percentage and whether the binder is cobalt or nickel. Nickel-bonded grades are often preferred where corrosion resistance matters more.
- Size accuracy: Check inner diameter, outer diameter, thickness, flatness, and surface finish.
- Quality testing: A serious supplier should check hardness, density, cracks, and dimensions before dispatch.
- Custom manufacturing: Your supplier should be able to make rings from a drawing or sample.
- Delivery time: For running plants, late delivery can stop production.
- Technical support: A supplier who asks about your application is more useful than one who only sends a price list.

Why Buy From an Indian TC Ring Supplier?
Buying from an Indian supplier can be practical for many businesses. You can communicate easily, get quicker technical support, and often receive replacement parts sooner. India also has strong manufacturing experience in tungsten carbide products, especially for rolling mills and industrial wear parts.
A local supplier can also help with repeat orders. Once they know your machine and ring design, they can maintain records and supply the same specification again. This saves time and reduces the chance of fitting problems.
Our Promise as a TC Rings Supplier
As a trusted Tungsten Carbide (TC) Rings Supplier in India, we focus on three things: correct material, precise manufacturing, and honest advice. We do not believe in selling a ring just because it looks similar to your old part.
We supply standard and custom TC rings for pumps, mechanical seals, rolling mills, wire-drawing machines, and heavy industrial equipment. Our team can help you select the right grade based on wear, heat, pressure, and the type of material your machine handles. TC seal rings are widely used in pumps, compressors, and other rotating equipment because they offer hardness, wear resistance, and chemical stability.
