What is the term for a metal alloyed to produce good wear factors?

The term "A.R." typically refers to "Abrasion Resistant" steel, which is specifically engineered to have excellent resistance to wear and tear. This type of metal alloy formulation is carefully designed to enhance its toughness and hardness, making it ideal for applications where sliding wear is a significant factor, such as in mining, construction equipment, and high-wear industrial machinery.

In contrast, stainless steel is designed primarily for corrosion resistance, while carbon steel is known for its strength and versatility but does not inherently focus on wear resistance. Tool steel, while offering high hardness and the ability to retain sharpness for cutting and drilling applications, is generally utilized for tools rather than applications where wear resistance under extreme conditions is the primary concern. Therefore, A.R. steel is expressly manufactured for scenarios where good wear factors are crucial.
