About Us

AISI O2 Steel, also known as DIN 1.2842, is a type of tool steel known for its oil-hardening properties. It comes in an annealed condition, offering excellent durability and a strong cutting edge retention. This steel is commonly used to manufacture round bars, sheets, and plates due to its impressive wear resistance.  

AISI O2 Steel is commonly used for manufacturing round bars, sheets, and plates due to its excellent wear resistance and good overall quality as a general-purpose tool steel.

AISI O2 Steel Round Bar Sheet Plate Supplier

Amardeep Steel supplies AISI O2 Tool Steel Round Bar, Sheet, and Plate, also known by its DIN 1.2842 designation. This oil-hardening tool steel is provided in an annealed condition, making it easy to work with before hardening. AISI O2 is known for its excellent durability and wear resistance, allowing it to hold a sharp cutting edge effectively. This makes it a great choice for general-purpose tool applications, especially when the cost of high carbon, high chromium tool steel isn't justified. AISI O2 can achieve a working hardness of up to 63-65 HRC, making it a reliable material for light to medium-use knives and various tools.
