Ar500 Rockwell Hardness. Abrasion resistant steel undergoes a two-step heat treatment process
Abrasion resistant steel undergoes a two-step heat treatment process called quenching and tempering, which alters the steel's grain structure to increase hardness and toughness. Feb 27, 2025 · Considered to be less tough than AR500 and is commonly used when the higher hardness (C54 vs C48) is desired like for weapon teeth Extra important to avoid sharp internal corners and stress concentrations to prevent cracks from forming AISI Alloy Steels (description here) AISI 4340 (43 HRC) Specialty Steel offers premium AR plate steel for construction, mining, and manufacturing. However, very hard steels like AR500 and AR600 may have reduced formability and machinability. . Although its exact chemical composition is often unspecified, it is engineered to achieve a surface hardness ranging from 477 to 534 BHN, equivalent to approximately 50 to 55 HRC. This grade has one of the highest levels of hardness out of the common AR steel plate grades – with a Brinell Hardness Number (BHN) of between 460-544 – and is typically used in high-wear and impact applications. May 17, 2025 · AR500 steel is characterized by its high hardness, typically ranging from 470 to 500 Brinell hardness (HB), which makes it suitable for applications that involve high wear and impact. When compared with AR400 steel, AR500’s increased surface hardness allows it to outperform in certain high-abrasion applications. Its tough core absorbs shock, while the surface remains incredibly hard to resist gouging and deformation. Much like AR450 and AR400, AR500 steel is a specific type of abrasion resistant steel with a surface hardness of 477-534 BHN. Can AR500 Steel Rust? Mar 13, 2025 · AISI AR500 steel is a high-carbon alloy with 477–534 HBW Brinell hardness, engineered for extreme abrasion resistance. Jun 5, 2023 · How is AR500 Steel Tested? AR500 steel is often tested using a Brinell hardness test, which measures the hardness of the material by indenting a hardened steel ball into the surface of the material. Choose AR400 or AR500 wear plates for lasting performance, durability, and resistance. AR 500 steel plates, and explore the differences in hardness, toughness, and applications to help you choose the right grade for your needs. Winco-Tuf 40 is for use in areas where AR400/AR500 are currently used. The plates are spec'd to be 470 - 550 Brinell hardness. Contact Clifton Steel for assistance. Nov 19, 2024 · Higher hardness improves abrasion resistance, making the steel last longer in high-wear conditions. 500 Brinell = 53 Rockwell C Jun 6, 2025 · So, what sets AR500 steel apart from mild steel? Is it the hardness, wear resistance, or perhaps the mechanical properties? In this article, we’ll delve into the key distinctions, comparing their hardness, tensile strength, and impact resistance. It is a high-carbon steel alloy that provides greater impact and sliding abrasion resistance by comparison. from publication: Mechanical properties and microstructures of steel panels for laminated composites in armoured vehicles What is AR500 Steel? Tensalloy™ AR500 steel is a grade of abrasion resistant steel plate that offers outstanding wear and impact resistance. 00 The Rockwell hardness of AR500 steel ensures that it can withstand repeated use without deforming or breaking, making it a long-lasting and cost-effective option for target shooting. 31 Chromium — 1. Download Table | Mechanical properties of RHA, AISI 4340 and AR500 steels. Apr 30, 2025 · AR500 Steel is a high-carbon alloy designed for extreme abrasion resistance. These approximate relationships between hardness and tensile strength do not apply to nonferrous metals, with the possible exception of certain aluminum alloys. Learn about the hardness and impact resistance of AR400 vs AR500 steel and choose the best option for your project. Sep 27, 2016 · In the case of AR400, the plate’s hardness would equal about 42 Rockwell C (HRC) or approximately 400 on the Brinell Hardness scale, while AR500’s hardness would be around 50 HRC or roughly 500 on the Brinell Hardness scale. AR500 is a grade of abrasion resistant (AR) steel plate that is known for its hardness, toughness, and resistance to wear and tear. Jul 9, 2025 · Compare AR 400 vs. I hardness tested some plates with a Rockwell hardness tester setup for the C scale. Winco-Tuf 50 if superior to standard AR500 plate. Physical Properties Tensile Strength — 210,000 PSI Yield Strength — 180,000 PSI Elongation in 2″ — 12% Hardness — 48-53 Rockwell “C” Brinell Hardness — 455-525 BHN Typical Analysis Carbon — . The AR500 Rockwell hardness is a measure of the steel's resistance to indentation or penetration. The diameter of the indentation is then measured and used to calculate the material’s Brinell hardness number (BHN). Typically, the harder the material, the more resistant it will be to abrasive wear. This hardness level makes AR500 Steel exceptionally durable under high-stress conditions.
