Saba, Multiple Alloying High Chrome Alloy Basket Bar .
Although the high chromium alloy cast iron strip has good oxidation resistance, it has some shortcomings such as low strength, poor toughness and easy fracture. And because of poor nickel metal, the cost of heat-resisting steel bar containing nickel used abroad is too high.

Because the graphite inside nodular iron is isolated distribution, there is no channel for oxygen to enter the metal, so the oxidation rate and growth rate is lower than gray cast iron, the use effect is better than gray cast iron. There is still a big gap between the high chromium alloy cast iron rods developed in recent years, but because of the simple production process, no need for heat treatment, low production cost and easy promotion, it is still used in small and medium-sized sinter Kamiyɔnw.
