Benefits of Polished Finish Stainless Steel Sheet
 

Increasing Resistance to Corrosion and Rust: After the stainless steel plate is left for a period of time or used for too long, a black or gray oxide layer will form on its surface. Its existence not only affects the appearance quality but also affects the performance. Therefore, it is necessary to take appropriate measures to remove it: polishing. Polishing can further improve the corrosion resistance and bright effect of stainless steel plates. It can also significantly help to reduce the number and size of crevices in metal that encourage rust.

 

Enhancing Aesthetics: Aesthetic is the number one thing merchants look for in their products. Through different polishing processing methods, the surfaces of stainless steel plates can have different levels of surface finish, which greatly improves the appearance of stainless steel and increases the appeal to consumers.

 

Removing Contaminants: Polishing eliminates unwanted blemishes, residue, and other contaminants from the surface, even if they’re invisible to the naked eye, which is undesirable for certain applications. In metallurgy, metals often are polished to enable better observation of their crystalline structures, defects, and discontinuities under a microscope.

 

Improving Cleanliness: Polished stainless steel metals are easier to clean than unpolished ones! Those smoother surfaces make it much harder for harmful bacteria and germs to latch onto them, meaning that you won’t need to clean your metals as often.

 

The Production Process of Polished Finish Stainless Steel Sheets

 
 

Melting
The elements of the stainless steel are first melted down together in a furnace for 8-12 hours. Often, scrap metal and recycled stainless steel is used for this process. The temperature at which the metal is melted will vary based on the grade of steel being made.

 
 

Carbon Removal
After the mixture is melted, extra carbon content must be removed. While carbon is an essential part of stainless steel, too much can create issues. Carbon can be removed in one of two ways: either through processing in an argon oxygen decarburization (AOD) converter, or through vacuum oxygen decarburization (VOD).

 
 

Tuning
After carbon removal, the metal mixture is fine-tuned to ensure that it meets the standard requirements of its grade. This involves the removal of excess elements and the balancing of the chemicals in the metal.

 
 

Casting and Forming
Next, the mixture is cast or formed into its shape. Some typical forms include blooms, billets, slabs, rods, and tubes. From here, the steel will be crafted into its final form.

 
 

Hot Rolling
Hot rolling is done at the temperature above the recrystallization temperature of the stainless steel. In this process, the metal is rolled, and the approximate form given at casting is made into a more precise form.

 
 

Cold Rolling
Cold rolling occurs just below the recrystallization temperature of the metal. This process uses multiple rollers and gives the metal an even more precise shape and a nice finish.

 
 

Annealing
During the annealing process, the metal is repeatedly heated and cooled. This helps to soften the steel and improve certain qualities like ductility.

 
 

Descaling
By this point in the manufacturing process, scale has generally formed on the steel. Scale can be detrimental to the steel and must be removed. This is achieved either by heating and cooling the metal further in an environment without oxygen, or by covering the metal in an acid mixture.

 
 

Cutting
After all these steps are completed, the steel can finally be cut. There are several methods that can be used to cut stainless steel. It can be cut mechanically with guillotine knives, circular knives, high-speed blades, or by using metal punches and dies.

 
 

Finishing
The final stage of stainless steel manufacturing is the finishing. Stainless steel comes in a variety of finishes achieved by different finishing methods. Among these are sand blasting, wet etching with acid, buffing, and polishing.

Terms Of Payment

We usually accept T/T, L/C, Paypal, Credit card, etc. If you prefer other payments terms, please feel free to discuss with us.

Shipping

If it is a sample, the volume is small and the weight is small. By FedEx, DHL, or TNT. It usually takes a week to reach your hands. If it is a formal bulk cargo, we have a cooperating freight forwarder. By sea, the timeliness is longer, depending on the distance to the destination.

 

FAQ

 

Q: Does polished stainless steel scratch easily?

A: While stainless steel isn't completely immune to scratches, with a little care and the right cleaning approach, you can keep your surfaces gleaming.

Q: How do you maintain polished stainless steel?

A: Apply a stainless steel cleaner/polish to a microfiber cloth.
Use the microfiber cloth to gently wipe the stainless steel surface in a side to side motion going with the grain.
Dry any excess cleaner or polish.

Q: What grade is polished stainless steel?

A: Considered the most widely used surface finish, 2B is the basis for most polished and brushed finishes. Such common stainless steel grades as 201, 304, 404L, and 316L come in a standard 2B finish.

Q: Does polished stainless steel look like polished nickel?

A: Yes, if you can't find the item you are looking for in Polished Nickel, the next closest finishes are Polished Stainless Steel, or Polished Chrome. As you can see from the above images, Polished Nickel has a slight golden tint as does, Polished Stainless Steel making them very close matches.
