Manufacturing Process of Stainless Steel Plates
Stainless steel plates are made through a process called hot rolling or cold rolling, depending on the desired thickness and finish of the plate. Here is a general overview of the manufacturing process:
1. Melting and Casting
The first step in producing stainless steel plates is melting the raw materials, which typically include iron ore, chromium, nickel, and other alloying elements. The molten metal is then cast into large slabs or billets.


2. Hot Rolling
Hot rolling is the most common method used to produce stainless steel plates. The slabs or billets are heated to high temperatures and passed through a series of rolling mills. The rolling process reduces the thickness of the metal and shapes it into a plate. The plate is then cooled and cut to the desired length.
3. Cold Rolling
Cold rolling is an alternative method used to produce stainless steel plates with a smoother finish and tighter thickness tolerances. After hot rolling, the plate is annealed (heat-treated) and then passed through a series of cold rolling mills. This process further reduces the thickness and improves the surface finish of the plate.


4. Finishing
After the rolling process, the stainless steel plate undergoes various finishing treatments to achieve the desired surface characteristics. This may include pickling (removing surface impurities), annealing (heat treatment to improve mechanical properties), and descaling (removing oxide scale).
5. Cutting and Forming
The finished stainless steel plate is cut into the desired sizes and shapes using shearing, sawing, or laser cutting methods. It can also be formed into different shapes through processes such as bending, stamping, or deep drawing.


6. Surface Treatment
Depending on the application, the stainless steel plate may undergo additional surface treatments such as polishing, brushing, or coating to enhance its appearance or provide additional protection against corrosion.
Precautions for Storing Stainless Steel Plates
-
During storage, attention shall be paid to moisture, dust, oil, etc., to avoid rust on the surface of stainless steel plates.
-
When water is immersed between the film and the stainless steel plate substrate, the corrosion rate is faster than that without film.
-
The stainless steel plate coated with the film shall be protected from direct sunlight. And the film shall be inspected periodically. If the film has deteriorated (the service life of the film is 6 months usually), it shall be replaced immediately.
-
If the packaging material is wet when adding padding paper, the padding shall be removed immediately to prevent surface corrosion.
-
Stainless steel plates can be stored outdoors and even be placed in a covered outdoor warehouse if necessary. But it is necessary to avoid exposure to sea salt, de-icing salts, and air pollutants such as acid mist and grinding dust.
-
When storing, the storage location should be convenient for lifting, and relatively isolated from other material storage areas.
-
Stainless steel plates should be inspected frequently after being put into storage. If there is any rust, the rust layer should be removed.
-
For some users with a larger storage capacity of stainless steel plate materials, there are some other storage rules. For example: Stacking according to the cross-section of stainless steel plates or stacking and storing together according to different furnace numbers (also known as batch numbers).

Process for Milling Stainless Steel Plates
Cleaning the Stainless Steel Plate
It is important to thoroughly cleanse the stainless steel plate, which eliminates any vestiges of dirt, debris, or contaminants that may impede the milling process or cause harm to the plate. You can use a cleaning solution in conjunction with a cloth devoid of lint to wipe the surface of the plate, ensuring that every nook and cranny is meticulously attended to. This step fosters superior adhesion of marking materials and precludes any undesirable disruptions during the milling process.
Marking the Desired Dimensions
Marking the desired dimensions on the stainless steel plate is an indispensable prerequisite for achieving precise milling outcomes.
Depending on the requisite level of precision, a variety of marking tools, such as scribes or markers, can be employed.
Securing the SS Plate on the Milling Machine

This measure is undertaken to avert any unwarranted movement or vibrations during the milling process, thereby ensuring the attainment of accurate and consistent milling results. Depending on the design of the machine, diverse clamping methods may be employed, ranging from the utilization of vices, clamps, or magnetic chucks.
Selecting the Appropriate Cutting Speed and Feed Rate
When milling stainless steel plates, it becomes imperative to carefully consider the selection of the cutting speed and feed rate. These two factors hold the key to achieving optimal results in this endeavor.
Choosing the Right Cutting Tool for Stainless Steel Plate
Stainless steel plate is a hard and abrasive material, requiring cutting tools that are specifically designed to withstand its formidable properties. Carbide or high-speed steel (HSS) end mills are commonly employed in the milling of stainless steel plates, owing to their remarkable hardness and resistance to wear. These cutting tools possess the ability to endure the high cutting forces and temperatures that are generated during the machining process.
Setting the Depth of the Cut
The depth of cut pertains to the distance that the cutting tool penetrates the material during each pass. In the case of milling stainless steel, it is crucial to avoid excessive depths of cut, for such a practice would give rise to increased cutting forces, heat generation, and wear of the cutting tool. Conversely, employing a shallow depth of cut may result in inefficient removal of material and prolonged machining times.
Ensuring Proper Chip Evacuation
The efficient removal of chips is essential in maintaining the efficiency of the machining process and safeguarding the cutting tool from harm. Stainless steel chips often tend to be long, stringy, and prone to adhering to the cutting tool or workpiece, resulting in the recutting of chips and a subpar surface finish.
Safety Precautions for Milling Stainless Steel Plate

This includes the donning of safety glasses or a face shield to shield one’s eyes from flying debris, a dust mask or respirator to prevent inhalation of metal particles or dust, and gloves to protect one’s hands from sharp edges and potential burns.
Ensuring the Work Area is Secured
Before milling stainless steel plates, it is crucial to secure the work area to minimize mishaps. Clear the surrounding space of any extraneous objects or clutter that may interfere with the milling process. Ensure that the workpiece is suitably clamped or secured to the milling machine’s table to prevent any movement or vibrations that could potentially lead to accidents.


Proper Handling and Disposal of Coolant
During milling operations, coolant is often employed to lubricate and cool the cutting tool and workpiece. It is of utmost importance to handle the coolant properly to avoid any health or environmental risks. Donate appropriate gloves when handling the coolant and dispose of it according to local regulations. Refrain from direct contact with the coolant and promptly clean up any spills to maintain a safe working environment.
Regular Machine Maintenance and Inspection
To ensure the safe and efficient milling of stainless steel plates, it is essential to carry out regular machine maintenance and inspections. Regularly inspect the milling machine for any indications of wear or damage, such as loose components or malfunctioning safety features. Lubricate moving parts as recommended by the manufacturer and promptly address any maintenance issues to avert accidents or machine failures.
