level of core martensite in high carbon rod 1

[larc69]

study - on core matensite in high carbon rod - effect on deep drawing (cold work) - internal ruptures. What would be the criteria to accept rod with core martensite?

What is the purpose of your question? The hardness and ductility of martensite are a function of carbon content - the higher the carbon content, the lower the ductility.
