Tin, antimony, manganese, molybdenum, chromium, vanadium ne niobium nyinaa betumi asiw graphite osutɔ ne ne nyin kwan, ɛma su a ɛne sɛ wɔbɛyɛ carburns no ayɛ kɛse, na ne nyinaa yɛ nneɛma a ɛyɛ den sɛ ɛbɛhyew kar no de. Nkɛntɛnso a molybdenum nya no fa ne dodow a wɔde ka ho no ho. Molybdenum a ɛwɔ dade a wɔde gu mu mu, .<0.8%, the effect of molybdenum is mild, which is to make the pearlite refinement, the content is the carburization stable element. It is generally believed that the role of manganese is to increase the amount of cast iron beads and improve the strength of cast iron. In fact, manganese is also multifaceted, when the content is high, it will make the graphite thick, thus reducing the strength of cast iron.
