Ferrite Scope testing measures the ferrite content in stainless steels and alloys using specialized instruments. This is critical because inappropriate ferrite levels may lead to hot cracking or reduced corrosion resistance. The method is widely applied to welds and components exposed to harsh environments such as power plants and petrochemical facilities. By ensuring the correct ferrite balance, this testing guarantees both the mechanical strength and corrosion resistance of materials, contributing to long-term reliability and performance.
