What is the surface roughness of SUS304 Outer Tie Rod?

Sep 11, 2025

Hey there! As a supplier of SUS304 Outer Tie Rods, I often get asked about the surface roughness of these parts. It's a pretty important aspect, especially when it comes to the performance and durability of the tie rods. So, let's dive right in and explore what the surface roughness of SUS304 Outer Tie Rods is all about.

First off, what's SUS304? Well, SUS304 is a type of stainless - steel that's super popular in the manufacturing industry. It's known for its excellent corrosion resistance, good formability, and high strength. When it comes to outer tie rods, these properties are crucial. Outer tie rods are a key part of a vehicle's steering system. They connect the steering gear to the steering knuckle, allowing the wheels to turn when you turn the steering wheel.

Now, let's talk about surface roughness. Surface roughness refers to the small, irregular deviations on the surface of a material. It's usually measured in micrometers (μm). The roughness of a surface can have a big impact on how the part functions. For SUS304 Outer Tie Rods, the surface roughness affects things like friction, wear resistance, and corrosion resistance.

A smoother surface generally means less friction. When the tie rod has less friction, it can move more freely within the steering system. This leads to better steering response and a more comfortable driving experience. It also reduces wear and tear on the tie rod and other connected parts, which can extend the lifespan of the entire steering system.

On the other hand, a rougher surface might seem like a bad thing, but in some cases, it can be beneficial. A slightly rough surface can help with the adhesion of coatings, like chrome plating. Chrome plating is a common treatment for SUS304 Outer Tie Rods because it enhances the corrosion resistance and gives the part a nice, shiny appearance.

We offer two types of SUS304 Outer Tie Rods: SUS304 Outer Tie Rod with Chrome Plated and SUS304 Outer Tie Rod without Chrome Plated. The surface roughness requirements for these two types are a bit different.

For the SUS304 Outer Tie Rods without chrome plating, we aim for a relatively smooth surface. A surface roughness of around 0.8 - 1.6 μm is typical. This smooth surface helps to minimize friction and prevent premature wear. It also provides a good base for any lubricants that might be used in the steering system.

When it comes to the chrome - plated SUS304 Outer Tie Rods, the initial surface roughness is a bit more critical. Before plating, we usually keep the surface roughness in the range of 1.6 - 3.2 μm. This slightly rougher surface allows the chrome plating to adhere better. Once the plating is done, the final surface roughness will be smoother, usually around 0.4 - 0.8 μm. The chrome plating not only gives the tie rod a better look but also adds an extra layer of protection against corrosion.

To achieve the desired surface roughness, we use a combination of machining processes. Turning is one of the primary methods. During turning, a cutting tool removes material from the surface of the tie rod to create the desired shape and surface finish. We also use grinding and polishing processes to further refine the surface. These processes can be adjusted to control the surface roughness precisely.

Quality control is a big deal for us. We use advanced measuring instruments, like profilometers, to check the surface roughness of every SUS304 Outer Tie Rod we produce. This ensures that each part meets our strict quality standards. We know that our customers rely on these tie rods for the safety and performance of their vehicles, so we don't cut any corners when it comes to quality.

In addition to the performance benefits, the surface roughness also affects the aesthetics of the tie rods. A smooth, well - finished surface looks more professional and high - quality. It gives customers the confidence that they're getting a top - notch product.
