1) poor chrome ore
贫铬矿
1.
Matching poor chrome ore of Xinjiang, Gansu, Qinghai and Vietnam with Indian chrome ore powder, of which Cr2O3 content is between 41%-43% Cr/Fe is 2.
用国内新疆、青海、甘肃等省生产的贫铬矿和越南贫铬矿,配以印度铬矿粉、入炉料控制Cr2O3 41％- 43％,Cr／Fe2。
2) poor chrome iron ore
贫铬铁矿
3) poor chrome
贫铬
1.
Lower solution treatment temperature of the raw material made the carbide didn't dissolve completely and distributed along the grain boundary like network,so poor chrome happened near the grain boundary and intercrystalline corrosion is produced.
通过对失效件0Cr18Ni9不锈钢制连接螺栓进行失效分析,得出其断裂原因为原材料固溶处理温度偏低,碳化物未充分溶解,并沿晶界呈网状分布,造成晶界附近贫铬,产生晶间腐蚀。

4) chromium depletion
贫铬
1.
The chromium depletion at a low-energy boundary segment introduced by twin emission into a random boundary was smaller than that of the original random boundary.
在大角度晶界上形成的局部的低能晶界的贫铬程度明显低于原来的大角度晶界的贫铬程度。
2.
The results showed that nitrogen alloying high purity steels exhibited no chromium depletion at grain boundaries after sensitized heat treatment, and showed mainly general corrosion in boiling 65% HNO 3 solution.
２０％）基本上消除敏化态晶间腐蚀，敏化处理不会引起晶界贫铬；当氮含量不超过０。
5) Cr-depleted layer
贫铬层
6) poor Cr theory
贫铬理论
补充资料：贫铬区
分子式：
CAS号：
性质：不锈钢表面或内部局部铬含量低于平均含量的区域。贫铬区的出现，通常是碳化铬析出的结果。由于铬是保证不锈钢耐腐蚀性的元素，贫铬区往往优先发生腐蚀。例如不锈钢中沿晶界析出碳化铬后导致晶界附近贫铬，从而容易发生晶间腐蚀。
