By exploring its physical, chemical, and mechanical properties, this article hopes to show readers when to choose 5160 steel over other, less well-suited alloys for their project. If you want someone else to tell you these things, and more, you could go to the knife makers' forum. 5160 is a low alloy steel known for its excellent toughness. 5160 is not for skinning a deer though. AISI 5160 steel, also known as 5160 spring steel, is a high carbon chromium alloy (maximum carbon content 0.61%, chromium content 0.9%). Company. California Do Not Track Notice. Can Your Company Help Provide Critical Supplies? It all boils down to the quality of the steel used to begin with. However, it all boils down to proper heat treatment. I want to weld on them, but I'm not sure about the correct filler, or prheat process. . A Katana made of this steel can be deceptively simple. It does not look sharp but, when used to cut it can make palm trees drop right to the ground. Alloy Steel 5160 is also in use in the automotive field in a number of different heavy spring applications, especially for leaf springs. 5160 is a low alloy steel known for its excellent toughness. This causes the blade to become brittle. AISI 5160 alloy steel is suitable for manufacturing leaf springs used in automotive field. Spring steel is a name given to a wide range of steels used in the manufacture of springs, prominently in automotive and industrial suspension applications. Because of its high carbon content, it is hard to weld. Note that this is not a comprehensive analysis, and to be considered 5160 steel, the material must also achieve the concentration tolerances for the other elements as shown below: 5160 steel is exceptionally tough and resilient. It would still be a good idea to use 5160 Steel to produce a 5160 Steel Katana. Alloy Steel 5160, also sold as AISI 5160, is a high carbon and chromium spring steel. The condition to look for are tight fittings and no traces of slipping through the hands of the owner. 5160 alloy steel handles repeated cycles of stress without breaking just like spring steel. We use cookies to ensure that we give you the best experience on our website. However, information on how to maximize the steel’s properties with heat treating is scant. These springs would be under a load so the welds would have to be non-brittle, and stong. In the case of 5160 aluminum, the 5 represents steel alloys that utilize chromium as the major alloying element. The yield strength describes the maximum tensile force that will not permanently deform a specimen of steel, and the ultimate strength is the maximum tensile force before failure (fracturing/cracking). A wide variety of 5160 leaf spring steel flat bars options are available to you, such as aisi, astm, and gb. Chromium is added to make the steel wear-resistant. Shot peened for longer life. COVID-19 Response: Source manufacturers & distributors providing COVID-19 medical supplies This article will explore the properties, strengths, and uses of 5160 steel, a low alloy high strength spring steel which is exceptionally resilient and tough. Website Last Modified November 29, 2020. Much like aluminum, steel is named using a four-digit identifier, but unlike aluminum, each number holds important information regarding the percentage of carbon and the associated alloying elements within the steel alloy. This simply means that this steel is good to use on most cutting tools. 5160 Spring Steel is made of chromium. 5160 Steel is used in truck springs and the like. 5160. Many manufacturers and spring shops use 5160 for springs but not all. Chromium is added to help prevent this rusting, but there is not enough by mass to fully prevent degradation. This material adds grain structure and makes the steel hard. Enlist Your Company ico-arrow-default-right. In terms of applying heat treatment, 5160 is normally hardened in oil. It can even make a sweepingly clean cut on a pool of noodles. AISI 5160 alloy steel is annealed at 788°C (1450°F) and then air cooled. Automobile leaf and coil springs are both good for making tools and knives. During the 1980s, 5160 was often used not just in manufacturing swords and blades alone. Forging must be done at a higher temperature between 2100 to 2200 F. It must be air-cooled after being subjected to heating at 1450 F. Round spring coil springs are better when producing swords because the cross-section flattens as needed. Sword makers use this to make the steel used to cut it take.
