why 316L stainless steel strip is used in syringe needle

Why 316L Stainless Steel Strip Is Used In Syringe Needle?

Grade 316L stainless steel strips are very popular materials for the production of medical syringes needles.

Its primary alloying constituents are chromium (16%–18%), nickel (10%–14%), and molybdenum (2%–3%), with small quantities of silicon, phosphorus & sulfur.

The presence of molybdenum makes the 316L stainless steel strip more resistant to corrosion than 304 stainless steel strip. 316L stainless steel strip has lower carbon than 316 stainless steel strip.

Let’s keep reading.

Grade 316L stainless steel strips are a very popular material for the production of medical equipment.

One of the medical equipment made from it is syringe needles.

The 316L stainless steel has attracted significant attention in both implantable and non-implantable medical devices because of its biocompatibility.

It is necessary to improve the anticorrosion and antibacterial properties of the 316L stainless steel strip to improve its quality for use in syringes.

What is 316L stainless steel syringe needle?

The grade 316L stainless steel strip syringe is not much different than a normal syringe.

It is just the grade of the steel which is different. The 316L syringe is used for many tasks. It is used to administer drugs and fluid into a body if a person is unable to take the drugs by his mouth.

A syringe is also used to extract blood samples and fluids from a person’s body, safely.

A common 316L syringe consists of a barrel with a piston on one end and a nozzle on the other end which connects to the needle. Some syringes may already have a needle attached to them.

Syringes have etched markings on their sides which shows the graduation in millimeters for accurate dispensing of drugs or removal of fluids.

What are the advantages of using 316L stainless steel strips in syringes needles applications?

There are many advantages of using a 316L stainless steel strip syringe needle as compared to other grades of syringe needles.

Grade 316L syringe needle has all the properties required to make an ideal needle for medical purposes.

Grade 316L stainless steel is very durable, has a tough texture, good elasticity, and resistance to corrosion.

It remains strong at elevated temperatures, has excellent pitting resistance and is also resistant to chloride.

All these properties help surgeons to work safely with the needle.

Why the edge burr and flatness of 316L stainless steel strips are so important in syringes needles production?

Deburring metals is an often overlooked process among industries and it is no exception for the production of 316L stainless steel strips needle production.

Deburring should be given much importance as burrs can cause issues in downstream machine processing.

When a burr interferes with a metrology device, it can cause issues in the machinery as it prevents the proper location of the part in a fixture or results in erroneous measurements.

A burr can be easily overlooked as you may not be able to detect it visually or by feel.

Burrs can also interfere with other measurements so it is very important to not skip the deburring process and make the materials as flat as possible.

How to produce one roll grade 316L stainless steel strip for syringe needle?

To produce one roll of 316L stainless steel strip, you will first need the raw materials of mother stainless steel coils.

The first step in order to produce one thin and precise roll is the rewinding process. This process will help ensure that the 316L produced will be of the best quality possible.

You will need rewinding machinery to examine any flaws that can decrease the quality of the product.

To achieve the required thickness of the roll, you will have to use a cold rolling mill which will also grant an excellent finish, flatness, and surface to the strip.

To change the structure of the 316L strip, we will use the heat treatment process.

During the rolling process, the 316L strip will become dirty and greasy due to oil and grease. The process of cleaning this mess is called degreasing.

After the rolling process has ended, the thickness of the strip will most likely fall between 0.02mm-1.0mm. To keep this thin strip straight, the stretch bending straitening process is required.

Finally comes the slitting process where machines will be used to cut the narrow strips for the slitting of super-thin 316L stainless steel strips.

The final thickness of the strip’s foil will likely range from 0.02mm-3.0mm.

The grade 316L stainless steel strip roll is finally ready to be used for the production of syringe needles.
