What’s the oxygen free copper?

Oxygen-Free Copper, abbreviated as OFC, generally refers to Copper with a 99.995% purity. Theoretically, oxygen-free copper is pure copper without oxygen or any residue of deoxidizer, but in fact, it contains trace oxygen and some impurities. The standard explains the content of oxygen is not more than 0.003%, the total content of impurities is not…

How to control the surface carbon content of carburized steel?

The surface carbon content and its distribution gradient of carburized steel parts have an important effect on its properties. High or low surface carbon content or decarburization will affect the surface strengthening of carburizing steel parts. In general, the carburizing process including carburizing → furnace air cooling → mechanical processing → heating quenching → cleaning…
