For 0.15mm thickness 304 stainless steel strip production process, do you want to learn more?
Here you will be able to get a clear understanding of how to produce 0.15mm thickness 304 stainless steel strip.
Let’s keep reading.
0.15mm Thickness 304 Stainless Steel Strip Raw Material Preparation
0.15mm thickness 304 stainless steel strip is made by 304 stainless steel coil.
304 stainless steel coil is a kind of high carbon austenitic chromium-nickel steel. It has the highest corrosion resistance and excellent weldability. It is the most widely used corrosion-resistant steel in the world.
304 stainless steel coil is made of sheet or plate. The material is supplied hot rolled, cold rolled or forged. It can be used for making various kinds of pipes and other industrial parts.
Checking the grade 304 mother coil raw material after they reach our factory, it is called incoming quality control.
Checking details include products thickness tolerance, width of coil, outside packaging, label marks, inside surface finish, chemical components, etc.
0.15mm Thickness 304 Stainless Steel Strip Cold Rolled And Bright Annealing Process
The first time cold rolling process: Our workers operate the advanced mill calender to make the hot rolled stainless steel mother coil with a thickness of 2.0mm~3.0mm into a stainless steel strip coil with a thickness range of 0.2mm~1.0mm. The first time bright annealing process: The 0.2mm~1.0mm thickness stainless steel strip is processed for bright annealing treatment. The strip can be fast cooled by the the continuous annealing line. The traveling speed of the stainless steel strip on the line is around 60m~80m/min.
The second time cold rolling process: After first time bright annealing process, continuing rolling the stainless steel strip with 0.2mm~1.0mm thickness into a new stainless steel strip with a thickness of 0.1mm~0.3mm.
The third time cold rolling process: After second time bright annealing process, continuing rolling the stainless steel strip with 0.1mm~0.3mm thickness into a new stainless steel strip with a thickness of 0.15mm.
0.15mm Thickness 304 Stainless Steel Strip Tension Straightening Process
When stainless steel strip is rolled on a 20-high rolling mill with a thickness of 0.15mm, it is a difficult-to-deform metal.
The stainless steel strip tension straightening process is a cold working process. The process has been designed to straighten the coil and remove any defects by pressing it between rollers.
The stainless steel strip tension straightening process starts with a coil of stainless steel strip which is fed into the tension straightener. Once the material has been fed into the machine, it is clamped between two sets of rolls while the rolls are rotated at high speeds. This action causes an increase in temperature and pressure which helps to straighten the material.
When the material exits the press, it will be straightened and will have no defects such as bends or kinks present in it.
The tension leveler unit line is equipped with plate automatic control system.
The excellence control and management to production process assures the straightness of metal strip with variety hardness temper.
0.15mm Thickness 304 Stainless Steel Strip Slitting Process
Stainless steel strip slitting is a process in which stainless steel strips are cut into smaller pieces or width. It is one of the most common applications of the stainless steel coil cutting process. The size of the resulting pieces depends on the 0.15mm thickness of the stainless steel strip and the width of the slit.
Stainless steel strip slitting is commonly used to cut coils into narrow ones for further processing or assembly into finished strips products. The process also allows manufacturers to save on material costs by reducing inventory levels and improving storage efficiency.
0.15mm Thickness 304 Stainless Steel Strip Inspection Process
0.15mm Thickness 304 Stainless Steel Strip Thickness Tolerance Inspection
- 0.15mm thickness: 0.15mm.
- Thickness tolerance: +0.00mm/-0.01mm (0.14mm-0.15mm).
- The inspection result: 0.147mm is ok.
0.15mm Thickness 304 Stainless Steel Strip Width Tolerance Inspection
- 0.15mm thickness width size: 30mm.
- Width tolerance: +0.0mm/-0.1mm (29.90mm-30.00mm)
- The inspection result: 29.97mm is ok.
0.15mm Thickness 304 Stainless Steel Strip ID Inspection
The 394 stainless steel strip inner diameter will be designed and produced as customer’s request.
For example, buyer wants 500mm inner diameter inner diameter coil with cardboard sleeve. You can see this cardboard sleeve on above picture.
0.15mm Thickness 304 Stainless Steel Strip Chemical Composition Inspection
0.15mm thickness 304 stainless steel strip chemical composition inspection is used to detect the content of Chromium and Nickel, which are the main elements in the 304 stainless steel strip.
304 stainless steel is a steel alloy with a minimum of 18% chromium content by mass. It is one of the most popular and widely used stainless steel alloys in the world. 304 has excellent corrosion resistance, so it is well suited for industrial applications where it will be exposed to atmospheric conditions and other corrosive environments. It contains molybdenum as an important alloying element, which increases its resistance to pitting and crevice corrosion in chloride environments.
0.15mm Thickness 304 Stainless Steel Strip Surface Finish Inspection
The surface finish of 304 stainless steel strip is evaluated by two methods: visual inspection and tactile feel.
Visual inspection is used to determine whether the surface is free of defects or blemishes that may affect the appearance of the product or cause problems in processing. Tactile feel is used to determine whether the surface has an acceptable smoothness or feel.
The surface finish should be clean, bright and free of foreign material including scale, discoloration, stains and dirt. The finish should be uniform across the width and length of the strip. Abrasive cuts should be free from deep scratches and grinding marks.
Depending upon the location of the defect on a finished strip, it may be necessary to remove all paint from that area before performing a visual inspection for blemishes such as chips or gouges.
0.15mm Thickness 304 Stainless Steel Strip Packaging
One kind of packaging for 0.15mm thickness 304 stainless steel strip is wooden pallet. And the fumigation wooden pallets and non-fumigation pallets are two kinds of pallets type.
Eye to eye or eye to wall types of packaging stainless steel strips will be adopted before shipment.
The surface finish of metal strips will be packaged with waterproof paper. Then coating the PVC film on this paper.
After that, the banding strap will be used for fastening pallets and strips products.
Before placing the metal strips into the wooden case, the strips are packaged with perfect packaging.
Wooden case and four corners shall not be smaller than the outer diameter of the total strips.
In addition, clear labels are tagged on the outside of these sea standard packages for easy identification of these 304 stainless steel strips specifications and quality information.
