0.02~0.05mm 301 Stainless Steel Foil , Over 20 Years Experience

When we want to know more about 301 stainless steel foil, something must be mentioned. In iron-based alloys with at least 10.5 percent chromium are in stainless steel. By creating an undetectable and attached chromium-rich oxide coating, they obtain their stunning properties.

Moreover, 301 stainless steel is an austinct steel with a cubic facial structure centered. In the annealed stage it is largely non-magnetic and may only be toughened with cold work. Increasing corrosion resistance in environments of chloride was added to enhance molybdenum. The decreased carbon percentage of this alloy offers an even stronger resistance to corrosion in welded constructions.

301 Stainless Steel Foil: Material Characteristics

Since 301 Stainless Steel Foils in stainless steel have high temperature and minimal maintenance corrosion resistance, they are nonmagnetic, well soldered and formable. Use in thermotherapy, water barriers, chemical tanks, heat exchangers, heat exchangers, fine stocks, chemicals, metal pins and shim. Recyclable 100 percent. Titanium-added rollers give greater resistance to corrosion and welding.

The 301 Stainless Steel Foil provides a high temperature oxidation resistance. These Foils can endure high temperatures and also have exceptional welding properties. These 301 Stainless Steel Foil are prepared and processed under the rinses. These have good qualities that are used in a wide range of applications. The foliage has low cost of upkeep and performance.

301 Stainless Steel Foil: Material Technicalities

The TFT substrate and the prototype displays in 301 Stainless Steel Foil is studied as superior in heat resistance and corrosion resistance. ss 301 Foil  is not conductive, so it is not required to develop an isolating film on your surface when utilizing it as a display substrate instead of a glass substrate. There are efforts to employ a stainless steel insulated foil as a substrate for TFT production.

Therefore the resolution of electronic paper display components etc. is regulated by the accuracy of TFT production, thus there is generally an enormous requirement for surface smoothness of the glass substrates for display use. 

On the other hand, the insulating film normally has a thickness of about 2 μm, such that the smoothness of the stainless steel foil surface itself also affects the surface smoothness. Then, following rolling, bright annealing is done to give the surface a mirror polish as a technique for flattening the surface of stainless steel foil.

The BA surface

A bright and rectified product is referred to as a “BA” and superior to a hard (H) material that is not rectified brightly. 

On a related note, for the H and BA treated surfaces of steel foil the Ra measured with a stylus-type surface roughness meter was 61 nm and 15 nm, while the Ra surfaces of the isolation films had rarenesses of 28 nm and 11 nm. The flatness of the BA material is higher than the H. It is also better, the smoothness of the insulating film that is created on it.

However, a brightly recalled BA material’s stainless steel foil has the problem of a poor recovery in shape, even depending on the density. When a film of approximately 150 μm thickness rolls into a tube of approximately50 mm diameter that can be handled by one hand, even when the rolling force is released, the foil will not return to a level surface. An uneven surface occurs when it tries to regain its shape aggressively.

A BA material is thought to be poorly restored due to strain removal and smoothing throughout the cleansing process. Whether the original form is reverted to after rolling is critical for a flexible display substratum. Until you are roll-up, it is difficult to use as a display unless you can spread flat and look up.

In addition, a TFT rear substratum is therefore necessary for flexible display use after rolling-up but up to now no approach has been detected for both surface smoothness and shape recovery.

The production process of 301 stainless steel foil


When it comes to the production of stainless steel foils from mother coils to final products, complete solutions may be found here. In several industry sectors we deliver precision rolls of rinsed stainless steel films.

We make incredibly high quality, super thin, 301 ss Foil which are exceptionally flat and are produced to tight tolerances to ensure precision for end customers. Each order is tailored to the exact needs of each customer. 

Notably, 301 Stainless Steel Foil has qualities that are unparalleled by other, thin films in many areas. The strong strength to weight ratio and corrosion resistance and oxidation are often desirable at high temperatures.

Constantly, the intricate and costly casting and ringing equipment involved are responsible for a substantial part of the high cost of making stainless steel foil via rolling. A procedure that makes (solid) chromized (coated) steel stainless steel, which is less expensive than traditional stainless steel processing like Type 430, will be detailed. Moreover, the material is more ductile and less work-hard during film processing, therefore removing intermediate treatments of annealing and minimizing scrap losses.


There are several surface treatments and grades for this material to withstand diverse situations. Chromium is used to prevent roasting and to survive in tough surroundings where steel is generally impossible. Chromium forms an unseen but protective layer that enables the sheet of stainless steel to remain radiant and protected in steel sheets.

Thus, 301 Steel Foils are provided with a range. In gages / size from.0005′′ to.010′′ our stainless steel is available and in temperatures ranging from the coated to hard to stainless steel rolling sheets and sheets. We have the ability to deliver materials with internal diameters on fiber, steel, aluminum and plastic cores.

The high-quality sheeting services in steel and other metals are necessary for stainless steel. For stainless steel, Aluminum and copper, we offer sheeting services. This foil sheeting solution is popular for industrial and automotive applications. Depending upon which gage you choose and the size of the steel sheets, we also provide shear and rotational sheeting techniques.


Due to the simplicity of the technique, low costs, high production capability and accuracy, micro punching has become a promising micro production process. But due to the challenges of tool making, the size of a pounded micro-hole is limited. In the paper we suggest a buckling design approach and a form of micro-die manufacturing technology for micro-punching. 

High dimensional precision micropunch and female die were made using micro-EDM with electrode blocking. In the precision micro punching tool, micro punching procedures were carried out of stainless steel foil with a micropunch and a female die. A nice profile and high dimensional precision pierced micro-holes diameter will show that the micro-produced is suitable for micro-punching processes.

It is important to communicate the specific requirements and intended use of the 301 stainless steel foil to the manufacturer to ensure that they can deliver the most suitable product for the application.

What Is The Difference Between 301 Stainless Steel Foil And Stainless Steel Strip Coil?

Both 301 stainless steel foil and stainless steel strip coil are made of stainless steel and are used in a variety of applications. However, there are some key differences between the two.

Composition of 301 stainless steel coil foil:

301 stainless steel foil is a type of austenitic stainless steel, which contains chromium and nickel. It is known for its high strength and excellent corrosion resistance.

Stainless steel strip coil, on the other hand, is a general term used to describe a variety of stainless steel alloys that are formed into long, narrow strips. The composition can vary depending on the specific type of stainless steel used.


301 stainless steel foil is typically sold in thin sheets or coils, and is used for a variety of applications including electronic components, springs, and automotive parts.
