316L Stainless Steel Strips For Capillary Tubes Production

Different types of stainless steel strips grades are in the market, all using multi-step processes to mill from stainless steel coils.

Here are many grades of stainless steel strips. The most common grade is 316L stainless steel strips. This grade of stainless steel has high resistance against corrosion.

The 316L stainless steel is very similar to 316; the main difference is that 316L has low carbon content in addition to Nickel, Chromium, Molybdenum, and Manganese.

The 316L stainless steel strips can be cold rolled for customer requirements to achieve the temper properties.

316L stainless steel strips for capillary tubes have to be cold rolled to meet customer specifications. They are an excellent option for heavy gauge welding due to their low content levels.

Let’s keep reading.

316l stainless steel capillary tube

316L stainless steel capillary tubes have small diameters and thick walls and are mostly used in measurement and instrumentation applications.

316L stainless steel capillary tubes are available in different sizes like outer diameters, wall thicknesses, gauge sizes, and grades we can make as our costumer’s demand.

The inner surfaces of these tubes are free from oil and grease from the easy supply of liquid and gases in precision instruments.

316L stainless steel capillary tubes are the best choice for our clients because they are very light in weight and very good in strength.

Capillary tubes of 316L grade are more precise and corrosion-resistant in weather conditions.

What are 316L stainless steel capillary tube applications?

The 316L stainless steel capillary tube properties make it suitable for various applications. It is chemically inert making it an excellent option for hospital, food, beverage, marine and other several applications that are sensitive to integrity and purity of products.

Some of the popular 316L stainless steel capillary tube applications include:

  1. Temperature sensor devices
  2. Heating Exchanges
  3. Gas pipelines and high-pressure liquids
  4. Manometers and flow
  5. Watches manufacturing
  6. Medical equipments
  7. Aerospace
  8. Power plants
  9. Telecommunications

Why use 316L stainless steel strips for capillary tubes?

This grade of stainless steel strip is very popular and in demand, also known as austenitic 316L stainless steel strip.

In the composition of 316L stainless steel, the addition of Mo (Molybdenum) and Ni (Nickel) enhance the properties like resistance against corrosion and increase strength at high temperature.

The 316L stainless steel strips have excellent properties like corrosion resistance, lightweight, and high strength.

These features set it apart from other grades like 304 stainless steel strip; that’s why we use 316L stainless steel strips for capillary tubes production.

Capillary tubes of this grade are very demandable in many industries like chemical processing, bioprocessing, and food and textile industries.

The benefit of 316L stainless steel strips

316l stainless steel strip

The production of stainless steel 316L strips follows a precise process.

Excellent grade 316L strips are highly recommended in challenging conditions. Due to its sustainability, it is used in several industries and industrial machinery.

Additionally, it provides incredibly great strength at extremely high temperatures.

However, the durability it offers is a big selling point for customers. Due to these benefits, the 316L stainless steel strips and better than other grades of steel strips like 304.

The 316L stainless steel strips have low carbon content and better resistance to rust and abrasion than other stainless steel grades.

This grade of stainless steel performs well at high temperatures and is easy to weld through TIG or MIG welding processes.

How to produce one roll 316L stainless steel strip?

1.Availability of raw material

We first need raw material to make one roll of 316L stainless steel strip.

We purchase raw material mother coils form reputed manufacturers such as POSCO and TISCO.

Every time we purchase raw materials, a quality certificate of the product is issued by the original manufacturer.


Rewinding is an essential process for producing thin, precise 316L stainless steel strips.

With the help of the rewinding machinery, we can examine the coils’ components for any flaws that can affect the final product’s quality.

Using this process, we can take the required precautions to ensure that the steel strips are of the highest possible quality.

3.Cold rolling

The ultimately required thickness of the steel strip is achieved using a cold rolling mill, which also guarantees the quality of the strip’s excellent finish, surface, and flatness to meet international standards.

4.Bright annealing

In bright annealing, we performed a metallurgical process on the whole body of the stainless steel strip.

With the heat treatment process, we can change the structure of the stainless steel strip to get our desired properties.


During the rolling process, the surface of the stainless steel strip becomes dirty due to oil and grease. Cleaning this surface of 316L stainless steel strip with chemicals is called degreasing.

6.Straitening process

After the rolling process, the stainless steel strip thickness is 0.02 mm-1.0 mm. it is difficult to keep this thin strip straight. For this purpose, we use the stretch bending straitening process.

7.Slitting process

Our personnel will apply small, precise machines to accurately cut the narrow, thin strip coils for the slitting of super-thin stainless steel strips. A thin strip foil’s thickness ranges from 0.02mm to 3.0mm.
