On the other hand, the martensitic class has typically much higher strength, but less corrosion resistance. For example, austenitic stainless steels are going to be the most ductile class of stainless steel, but also the most corrosion resistant. The strength and the corrosion resistance of the stainless steel is dependent on these microstructures. Duplex stainless steel is a mix of austenitic and ferritic microstructures, and precipitation hardening means that precipitates can form to increase the strength of those class of stainless steels. These stainless steels are named after the microstructure that forms in those alloys. There are five classes of stainless steels: Our goal is to increase the value of your scrap metal.Stainless steels are characterized by a chromium content higher than 10.5% by weight. If your business has any of the grades of steel described in this article or other scrap metals that can be recycled, give us a call at (623) 931-5009. Tool steels are often used in cutting and drilling equipment. They consist of cobalt, tungsten, molybdenum, and vanadium in shifting quantities, depending on needed staying power and heat resistance.įor more information about identifying different types of steel, visit these resources:Īt Consolidated Resources, Inc., we strive to provide the very best industrial recycling solutions to Arizona businesses. You can find alloy steels within auto parts, electric motors, rails, construction equipment, and wires. Carbon steels account for 90% of total steel production.Īlloying elements which can be silicon, nickel, copper, and aluminum make up some of the internal components of alloy steels. The inexpensive price point makes it easier to be the main component of such large projects. ![]() Popular for its corrosion resistance, it’s about 200 times more resistant to corrosion than mild steel.Ĭarbon steel is widely used within the construction industry and can be used to make bridges, pipelines, and skyscrapers. It’s very prevalent within restaurant kitchens including countertops, silverware, and pots and pans. ![]() With ten percent or more chromium added to prevent rust, stainless steel, which is a carbon steel, can be used to hold hot liquids and food items. One common recognizable steel item is a galvanized trash can. The surface of steel must be protected, galvanized, or painted as it can easily rust. Tool Steel – cutting and drilling tools 1% – 2% carbon High-Carbon Steel – springs and wire 0.6% to 1% carbon Medium Carbon Steel – forging and vehicle parts 0.3% to 0.6 % carbon Mild Steel – used in pipe and steel framing 0.05% to 0.3% carbon Grading systems are used to distinguish steels based on their specific properties. By appearance alone, it can be tough to differentiate numerous types of steel. Each grade has its own individual chemical and unique physical qualities. There are over 3,500 different grades of steel according to the World Steel Association. In this article we offer a brief introduction to the various grades and common types of steel, one of the many materials CRI processes. Many business owners aren’t aware of the financial & environmental benefits of recycling their metal scrap. ![]() At Consolidated Resources, Inc., we believe it’s important to educate our current and future customers about the materials they can recycle.
