When treating steels to improve their hardness and strength, two quench and tempering processes stand above the crowd: austempering and martempering. Austempering basically involves tempering carbon steel in molten salt solutions between 500 and 800 degrees Fahrenheit into a product known as bainite, whereas martempering involves tempering carbon steel in hot oil between 350 and 450 degrees Fahrenheit into a product known as martensite. While both tempering processes will yield reasonably decent results, austempering carbon steel into bainite for pipe manufacturing purposes has some advantages over martempering the steel into martensite instead. These 3 particular advantages make buying bainite better for pipe manufacturing purposes.
Austempering steel into bainite is highly recommended for producing metal sheets used for pipe manufacturing purposes. Bainite is perhaps one of the most ductile metals available at the moment, as it can be pressed into just about any shape while it is still cold without cracking. In fact, bainite delivers 7% more strength than martensite when it comes to its ability to bend when it is being cold pressed into various shapes.
This feature of bainite makes it better for the purpose of manufacturing pipes, as the metal sheets can easily take on more shapes without cracking. As a result, your manufacturing plant will be able to bend the metal sheets into pipes of various diameters with ease. You can even bend the pipes into different shapes. The ductility of bainite also allows you to make pipes with thin sheets of metal.
Bainite pipes are used in heavy-duty applications. For example, these pipes are often used as filters for automotive purposes and are even used in military applications. In the past, bainite was used in World War II extensively for manufacturing gun parts. Think about it this way. If bainite can handle the explosive forces within a gun, it can handle just about anything. These pipes are recommended for construction work, residential projects and more. With that said, the toughness of the pipes you can produce will greatly influence the type of clients and customers you can cater to. Pipes that can withstand more force without cracking or becoming distorted are in high demand and will take your manufacturing plant to new heights.
Bainite pipes made from austempered steel are as tough as it gets. The microstructure of the metal is more uniform and less disturbed even when compared to steel that has been martempered. As the metal is tougher, you also won't have to worry about having to handle these raw materials with care.
Quick Production Rates
If your manufacturing plant requires large numbers of metal sheets, your orders will be fulfilled much more quickly if you go with bainite rather than martensite. One of the main advantages of austempering is that it does not require a final tempering process, unlike martempering. This makes producing bainite a much less time consuming process, so you'll be able to fulfill your orders much more quickly without having to worry about production disruptions from lack of supply.
As bainite takes considerably less time to produce, it is also highly valued for being energy efficient. As the technology for austempering carbon steel improves, the cost of bainite metal sheets will lower with time.
Metal sheets that have been tempered via austempering or martempering are both considered high quality goods. However, if you're looking to take your plant to a completely different level and produce pipes that are able to handle and withstand more force, using bainite will be your best bet. Bainite possesses many desirable qualities that make it ideal for numerous different types of applications and purposes.
