Corrosion test shows that proper rareearthaddition enhance the general corrosion sensitivity.
腐蚀试验表明,添加微量稀土元素可增强抗点腐蚀敏感性。

Addition of strengthening elements can further improve heat-resisting strength; while light rare-earth elements can reduce the production cost instead of Y.
加入强化元素能进一步提高合金的热强性。用轻稀土元素代替Y则能降低生产成本。
