Common Grades & Properties
There are numerous grades of stainless steel sheets are available on the market, they are generally defined according to their manufacturing processes and alloying composition. They all have common features such as durability and resistance to rust, corrosion, and stain. However, there are still a few slightly different properties between these grades. There are two common grades of stainless steel sheets (304 and 316) that we commonly used for your projects, you need to consider some factors below:
304 Stainless Steel Sheet
A stainless steel sheet with 304 grade is perfectly used for a wide variety of general-purpose and light-duty applications. It highly contains chromium and nickel elements, which help enhance its resistance to water, humidity, and oxidation. The properties of 304 stainless steel sheet metal include:
In addition to commonly being used for architectural & decorative projects, 304 stainless steel is perfectly ideal for food and healthcare applications, as it can resist most oxidizing acids and some corrosive substances. However, 304 stainless steel comes with one weakness, it will gradually get corroded once locate in chloride environments, or in coastal areas with a salt atmosphere. Chloride irons can cause some corroded areas, defined as “pitting”, which can spread under the protective layer of chromium to damage internal structures.
316 Stainless Steel Sheet
316 stainless steel has some properties the same as 304 stainless steel, it also highly contains chromium and nickel. However, 316 has more molybdenum to further enhance the resistance to stronger corrosion to chemicals, particularly to chlorides or chlorinated substances. 316 stainless steel metal with these benefits is ideal for some applications rigorously required sanitary and hygiene like medical instruments & food processing facilities, and other environments with highly corrosive conditions like chemical factories. The properties of 316 stainless steel sheet include:
316 stainless steel is generally utilized in many industrial applications like chemicals, and some somewhere with high-salinity such as coastal areas, 316 stainless steel is properly used to manufacture medical / healthcare appliances and food processing facilities.
Decorative Options For Stainless Steel Sheet
For different visual effects and application purposes, there are a variety of types of surface finishes for stainless steel sheet. All of them can bring you added value, such as aesthetic appearance, corrosion resistance, durability, and more. But different options of surface finishes provide different properties, performances, and processing costs, so it’s so critical to consider your specific needs when choosing the suitable surface finishes for your stainless steel sheet.
For corrosion resistance and durable applications, the decorative stainless steel sheet would be better to be made of other metal types. It’s not only suitable for a wide range of architectural purposes but also can be customized according to customers’ bespoke requirements. The patterns of the embossing or opening hole in decorative sheet metal & plate is fabricated by the process type and the shape of the mold. As a custom-made metal fabricator, TBK metal provides various surface finishing services that are suitable for different metal types, including stainless steel, aluminium, copper, galvanized steel, and so on.
Difference Between Stainless Steel Sheet & Plate
Stainless steel sheet & plate are absolutely not the same, they are typically different in their thickness. The more the thickness, the stronger the strength, different thickness is used for a different purpose. Below are the properties for stainless steel sheet and plate:
Stainless Steel Sheet
Stainless steel sheet generally features a thickness not more than 6mm, it’s usually utilized for architectural structures and decorative material without extra durability requirements. Stainless steel sheet comes with corrosion resistance and is well suited for cladding, roofing, railing, and ceiling.
Stainless Steel Plate
The thickness of stainless steel plate is typically more than 6mm, and it’s usually applied in purposes where required high durability and strength are more than the weight requirement. It is used in architectural structures and industrial applications where durability is required to pass strength & tenacity testing.
What Is Stainless Steel?
Stainless steel is also typically called rustless steel, which is an iron alloy consisting of chromium more than 10.5%, carbon less than 1.2%, and a small amount of other alloying elements such as nickel, titanium, molybdenum, manganese, niobium, etc. Unlike common steel, stainless steel has chromium as the essential element, which can enhance its resistance to rust, corrosion, stain, and heat, not only that, these elements can greatly improve steel with better mechanical properties.
Compare with common steel, stainless steel doesn’t rust and corrode when being in contact with water or air, and the surface is extremely easy to clean and maintain, perfectly suitable for some applications that highly required hygiene and low pollution, such as kitchens, food processing factories, pharmaceutical factories, hospitals, etc. And another significant property of stainless steel is that it has a wide range of surface finishing options, such as anodizing, brushing, etching, embossing, mirror finishing, etc. All these finishing processes provide stainless steel with a variety of unique and stunning effects, which make it versatile for various applications, including architectures, decorations, furniture, appliance enclosures, and so on.
Compositions Of Stainless Steel Sheet
The major material of stainless steel sheet is iron, which is the plain steel simply consisted of steel and carbon. For optimizing the properties of steel, we can melt the carbon steel together with some other elements, such as chromium, molybdenum, silicon, nickel and some additives. Such an alloy of iron is more resistant to rust than the carbon steel, as the added elements mixed together can form an inert oxide layer that can protect the surface from corrosion and stain.
The capability of resistance to oxide or corrosive substances is effected by the proportions of alloy elements including steel, chromium, molybdenum, nickel, etc. Which means that different types of stainless steel are determined by the ration of steel to other elements. In addition to the resistance, the difference of proportion also effects other mechanical properties such as strength, ductility, melting point, etc. Different types of stainless steel alloys are classified by different ratios of their alloying elements. these alloy compositions are assorted to different grades of stainless steel such as 201, 304, 316, 410S, 430, and so on.
