High-Performance Steel for Tough, Durable Components

SIQUAL 7225 is a chromium, molybdenum, and manganese low alloy steel, with good toughness, torsional strength, and fatigue resistance. It is ideally suited for both statically and dynamically stressed components in vehicles, engines, and machinery. This steel is particularly effective for parts with larger cross-sections, such as crankshafts and gears.

Manufacture

SIQUAL 7225 is made by SIJ Acroni and SIJ Metal Ravne. The manufacturer depends on the steel's final form, affecting its physical properties and chemical composition.
