What Is Stainless Steel Plate?
By definition, stainless steel plate is a type of metal sheet with a minimum of 10.5% to 11% chromium and other elements. The existence of chromium content makes it not easy to corrode, rust or stain as ordinary steel does. But despite the name it is not fully stain-proof, it will begin to corrode most notably under low oxygen, high salinity, or poor circulation environments. The specific level of corrosion resistance depends on the amount of chromium added to the melt. That’s why the stainless plate is available in numerous grades to satisfy people’s different needs.

How Is Stainless Plate Made?
Stainless steel in the plate is often manufactured by the rolling process. But depending on its specific procedure, it can be divided into hot rolling and cold rolling processes.
Hot rolling is rolled at high temperatures. This makes steel easy to form and fabricate but not easy to precisely control sizes and dimensions after processing. And it often has a scaled surface. Therefore, this kind of stainless plate is much cheaper than a cold-rolled one. The specific operation process of hot rolled stainless steel plate is as follows:
Billet — heating — dephosphorylating — hot rolling — annealing — pickling — sizing — examining — packing
Cold rolling is often operated on the basis of the hot-rolled stainless plate when it is cooled. By comparison, it has a smooth finish, closer tolerance, and stronger hardness, but a relatively higher price. Here is the general process of the cold rolled stainless plate for you.
Hot rolled stainless plate — rolling — annealing — pickling — sizing — testing — packing
Product Advantages
Stainless steel has many important properties over other ordinary metal materials. Some key properties are listed below:
1. Superior Corrosion Resistance
Usually, a stainless plate is regarded as an iron alloy that includes a minimum of 10.5% chromium. That is, when exposed to oxygen, the chromium in the stainless steel will oxidize, creating a layer of chromium oxide that protects the underlying iron from rust-causing corrosive elements (acid, alkaline gas, solution, and other media) in the surrounding environment. To meet the varying needs of stainless steel components, different grades have been formulated to enhance anti-corrosion performance by industry standards.
2. High Strength
Stainless steel in the plate is strong and highly durable due to its impressive hardness. This feature is primarily due to the presence of two key components: chromium and nickel. Chromium forms an oxide layer on the metal’s surface, protecting it from corrosion and wear. Meanwhile, nickel contributes to the metal’s strength and ductility, enhancing its overall hardness.
3. Good Processing Performance
Like other steel materials, stainless metal plates can be easily processed and shaped, including drawing, cutting, bending, etc.
4. Thermal Conduction
The thermal conductivity of stainless steel depends on its complex composition and tidy surface. Therefore, its conductivity of heat is very good. Typically, stainless steel product has a thermal conductivity ranging from 15 to 20 W/mK (watts per meter Kelvin). Due to this, it keeps more energy that stabilizes the surrounding temperature.
5. Aesthetic Appeal
Unlike conventional steel, stainless steel usually has a glossy and smooth finish, which is sought after by many people.
6. Long Service Life
Stainless steel product is an extremely durable and well-aging material. Due to its strong rust resistance and advanced manufacturing technology, our stainless plate product usually enjoys a lifespan of more than 50 years. If the right stainless steel grade is selected, it may survive longer.
7. Easy Maintenance
Its smooth finish can hinder the accumulation of dirt on the material surface. Also, the metal texture makes it easy for you to clean and sanitize. Therefore, it requires little to no maintenance and hence becomes a very cost-effective material.
8. Quality Assurance
