Which material property limited Song Dynasty musket bore manufacturing?

💡 Explanation

Lower tensile strength in Song-dynasty cast iron meant gun barrels risked shattering under explosive pressure because higher pressures exceeding the material's yield strength caused catastrophic crack propagation, therefore tensile strength limited bore manufacturing sizes, rather than material malleability or corrosion resistance.
