järnkrom
Järnkrom is a historical term used in Swedish metallurgy to describe chromium-containing iron alloys. The name combines järn, meaning iron, with krom, derived from chromium, and it has appeared in Swedish-language texts to denote early attempts to enhance iron with chromium for better wear resistance and, to some extent, corrosion resistance. The concept predates the widespread use of modern stainless steels and reflects an era when alloying elements were increasingly explored to improve steel properties.
In practice, järnkrom referred to iron alloys into which chromium was added during smelting or refining. The
Today, the term järnkrom is largely obsolete in technical usage. Modern metallurgy distinguishes stainless steels by
