Stainless Steel Sheet

Stainless steel is a combination of several metals that, when mixed, are tougher and more durable than they are when separated. By adding to and removing ingredients from these alloys, engineers have created several types of stainless steel sheet metal, each with unique uses and characteristics.

Stainless steel is versatile enough to be used for everything from kitchen equipment to heavy machinery. To make the right decision when buying sheet metal, it’s important to understand each alloy’s ingredients, the steel grading system, and the different kinds of stainless steel.

​Crucial Terminology
In the description of different types of stainless steel sheet metal and their aspects, several terms are frequently used. In this section, we’ll explain the meaning of these terms and their effects on the finished product.

• Stainless steel is an affordable, durable type of sheet metal that’s used in a range of applications. It’s quite strong, which makes it great for use in construction.
• Corrosion occurs when stainless steel degrades into a more stable form. Rust is the most common type of corrosion, and stainless steel is highly resistant to rust, but it will eventually corrode if it is exposed to excess moisture, acids, or salt.
• Alloys are blends of several different types of metal. For instance, our stainless steel sheet metal is made by combining carbon, iron, and other metals.
• An element is a substance at its most basic level. In chemistry, the term refers to atoms with an equivalent number of protons. Elements are combined to form alloys, of which stainless steel is one of the most well-known.
• Chromium is a crucial component of stainless steel, as it helps make the alloy resistant to tarnishing, corrosion, and stains.
• Nickel, when added to steel, gives the alloy additional strength and stability. Another reason to add nickel to certain types of stainless steel sheet metal is that it imparts a lustrous shine.
• Carbon hardens sheet metal and reduces the speed with which it wears down. High-carbon stainless steel is often used to make knives, flatware, and other professional kitchen gear, which must be durable enough to stand up to years of daily use.

Now that we’ve discussed some of the most frequently used terms in the stainless steel manufacturing industry, we’ll cover the systems by which sheet metal is graded.

The Stainless Steel Grading System
There are numerous kinds of stainless steel, which vary according to their content and application. To differentiate between these types, the industry has devised several 
grading systems for use in different settings and countries. For instance, the foodservice industry uses two grades: flatware and SAE.

• SAE grading was devised by SAE International, an engineering group that develops standards for workers in manufacturing industries. To distinguish between grades, the SAE system uses whole numbers. The AISI system is also used; it’s a byproduct of the American Iron and Steel Institute.
• The flatware grading system uses ratios such as 18/10, 18/8, and 18/0 to denote food grade stainless steel’s chromium and nickel content. These two metals are an important part of the kitchenware manufacturing process, as they determine the shine, magnetism, and corrosion resistance of sheet metal.

In the sections below, we’ll break down the most common types of stainless steel in use today.
Different Stainless Steel Types
There are nearly 200 types of stainless steel, each with different properties. In the hospitality industry, it’s particularly important to know these differences, as certain types are best for some tasks. For instance, if you’re looking for cookware for use with salty foods, 316 stainless steel is preferable because it’s resistant to corrosion. Understanding the many differences between stainless steel types and grades will help you make an informed decision when buying sheet metal.

Stainless Steel: An Eco-Friendly Option
It may seem counterintuitive, but steel is good for the planet. It’s an environmentally friendly option for numerous commercial and industrial applications. Because of its composition, it can be recycled nearly endlessly without a decline in performance. Several studies show that almost all sheet metal applications, from appliances and packaging to automobiles, contain recycled metal. When you buy stainless steel sheet metal from a metal supplier, you’re probably buying a recycled product.

Building a Safer Medical Environment
Stainless steel sheeting is ideally suited to the medical environment as it is corrosion-resistant and easily sterilized. This type of sheet metal is sometimes used in the construction of operating tables, MRI scanners, and other medical equipment. Stainless steel is also used in surgical implants such as artificial hips and replacement joints. Pins and plates made of stainless steel are often used to hold broken bones in position as they heal.

Powering Heavy Industry
The gas, oil, and chemical industries operate in high-pressure environments involving toxic substances and high heat. Special grades of sheet metal have been created for industrial use, and these grades offer increased corrosion resistance over a greater temperature range. This kind of steel is often used in the construction of pipes, tanks, and other parts.

One type of sheet metal, which is known as super duplex steel, can be made in enormous sheets. This manufacturing method maximizes the metal’s structural integrity while minimizing the need for welding. Because it’s so strong, super duplex steel reduces the need for additional structural support, which makes it a popular choice for construction projects on a tight budget.

Use Stainless Steel Sheet Metal for Extra Security
Aside from its other applications, stainless steel is a great choice for doors. This type of sheet metal is commonly used in bullet- and fireproof doors, which makes them popular options in commercial buildings, stores, and schools.

Steel plates are a great choice for outside doors because they’re nearly impervious to bowing, cracking, and corrosion, and they’ll hold up well in the harshest conditions. When buildings hose precious and valuable things, steel doors offer increased security and protection.

Conclusion
Stainless steel sheet metal is a versatile, adaptable material that’s used in a range of foodservice, medical, and industrial applications because of its durability, strength, and resistance to corrosion. By learning about the properties and types of stainless steel, it’s possible to make a more informed purchase decision.
