Types of Sheet Metal
Sheet metal is used in a wide variety of projects. It’s a metal product that has been rolled into thin, flat pieces during the industrial process of hot and cold rolling.
It is usually sorted and sold by its thickness, which is measured in gauges and converted to inches or millimetres. Different metals have different gauge systems.
Alloy Steel
Alloy steel is made by combining iron with other metals, such as nickel, chromium, vanadium, molybdenum, and tungsten. These additions give the material its strength, durability, and resistance to corrosion and damage over time. The alloying elements also play a role in the material’s ductility and hardness.
Alloyed steel is used in a variety of applications, including automotive manufacturing, construction, and food processing. It is also an essential ingredient in products that must perform in high-temperature or corrosive environments. Aerospace and defense companies also rely on alloy steel components for their structural integrity and mission success.
Some of the most popular types of alloy steel include low, medium, and high-alloy grades. Low-alloy steel contains less than 8% of alloying elements, while mid- and high-alloy grades contain between 8% and 15%. These additions increase the metal’s tensile and ductile strength, toughness, and heat resistance.
Stainless steel is an example of a high-alloy grade, and it is incredibly strong and durable. It is often used for building construction, such as beams and flooring, as well as in appliances like refrigerators and washing machines. It also offers exceptional corrosion resistance and can withstand heavy loads. steel sheet metal It can be rolled into sheets and plates or stamped into a variety of products, including rain gutters and metal ductwork. Steel sheets and plates can also be used to create cladding for building exteriors, protecting them from weather damage.
Stainless Steel
Although not cheap, stainless steel has many benefits that make it a good choice for those looking for sheet metal fabrication. It is durable and resistant to corrosion. This is due to a naturally occurring protective layer of chromium oxide that covers the steel surface. It also has good strength and heat tolerance. This makes it suitable for a variety of applications and industries.
Stainless steel is available in a range of grades that are categorized by their specific properties. Grade 304 is one of the most popular. It contains 18% chromium and 8% nickel. This combination provides good resistance to corrosion from acids and other chemical compounds. This is an ideal material for kitchen equipment and sinks, as well as other items that are exposed to corrosive environments. It can also be found in medical and pharmaceutical devices, vehicle parts, and aircraft components.
Stainless steel is usually made using an industrial process that involves passing the molten metal through rollers to achieve the desired thickness. This is followed by annealing to relieve stresses and improve its physical properties. It can then be cut to order with tools such as guillotine knives, circular saws and high-speed blades. It is then ready to be finished with grinding and polishing. The result is a high-quality, low-maintenance metal that is ideal for the construction industry for exterior cladding and structural beams, and for functional piping.
Carbon Steel
Known for its durability and strength, carbon steel can be manufactured into a wide range of shapes, sizes, and thicknesses. This type of steel can be used for everything from building structures to automotive parts and components. Carbon steel also resists corrosion very well.
It is also easy to machine and weld. This is important when working with large scale projects that require precise measurements. Carbon steels are also relatively inexpensive compared to other metals.
There are different types of carbon steels based on their carbon content. The lowest grade is known as wrought iron, which is often used for fencing, gates, and railings. The middle grades of carbon steel, called mild steels, are easier to work with and can be made into many structural applications such as buildings and bridges. They are also commonly found in vehicle parts and accessories like axles, shafts, and gears.
The higher grades of carbon steel, such as AISI 1008 and 1010, are even easier to work with due to their low carbon and manganese chemistry. They can be easily welded and have good carbon steel manufacturer machinability, but may need to be pickled and oiled to ensure they remain resistant to corrosion. They are used in automotive and commercial equipment like motor and pump shafts, tools, and machine parts. They are also used to make decorative sections of vehicles such as wheel covers and nuts, bolts, and screws.
Galvanized Steel
Steel structures that will be exposed to the elements often require galvanized sheet metal. This material is durable and resistant to rust and corrosion. It is also more cost-effective than other types of steel sheets. The zinc in galvanized steel provides a barrier that protects iron from oxygen and moisture, significantly decreasing its susceptibility to rust. This protective layer also helps prolong the lifespan of the steel.
To create galvanized steel, machinists clean the base metal by either chemically or mechanically preparing it for the hot-dip process. It is then dipped into a pool of molten zinc. The machinists recoil the steel immediately afterward to ensure that all areas are coated and there are no gaps or inconsistencies.
Another method of creating galvanized steel is through electrogalvanization, which doesn’t involve the dipping process. Instead, electric currents are run on the metal, which causes the zinc to adhere or bond with it more closely than in the hot-dip method.
Both the hot-dip and electrogalvanization processes are effective at producing high-quality galvanized steel. In terms of appearance, galvanized steel typically displays a speckled pattern, with darker and lighter spots appearing throughout its surface. This unique look can help add visual interest to a project or design. Like regular steel, galvanized steel retains its inherent magnetic properties and can be molded into various shapes to suit specific projects.
