Since high carbon alloy steels is HRC 55~65 in hardness and 1.5%~2.5% in Carbon Equivalent, high-carbon-alloy-steel surfaced metals generally were selected in order to maintain high hardness and wear resistance of weld repaired layer, of which high-carbon Cr-Mo-W surfaced metal had been most widely used with 300~500℃ preheat or heat-treat after welding to improve its crack resistance.

由于高碳合金钢的碳当量高达1.5％～2.5％，硬度一般为HRC55～65，为了保证修复层的高硬度和耐磨性，焊接材料常选用高碳合金钢质堆焊金属，目前最普遍采用为高碳Cr－Mo－W系堆焊金属，但必须采用350～500℃高温预热焊和焊后热处理工艺措施以保证其具有一定的抗裂性。

Such materials are characterized by good insulation and high resistance to wear.

这些材料的特点是：绝缘性好，耐磨性强。

Such materials are chiefly characterized by good insulation and high resistance to wear.

这些材料主要的特点是：绝缘性好，耐磨性强。

In high ─ speed steel, molybdenum can replace parts of tungsten.

钼铁是钼与铁的合金，它的主要用途是在炼钢中作为钼元素的加入剂，钢中加入钼可使钢具有均匀的细晶组织，并提高钢的淬透性，有利于消除回火脆性，在高速钢中，钼可代替一部分钨，钼同其他合金元素配合在一起广泛地应用于生产不锈钢、耐热钢、耐酸钢和工具钢，以及具有特殊物理性能的合金，钼加于铸铁里可增大其强度和耐磨性。

本闸门是由圆型门框、闸板、导轨、密封条、可调整密封机构等部件组成，其密封原理是门框固定于水池圆型管道及墙壁上，导轨固定门框与墙壁上，闸板通过导轨做启闭动作，直到闸板上的锲块碰到导轨条上的锲块，使得闸门密封面紧靠门框上的密封面，从而起到密封效果，另外闸板密封面跟门框密封面都是镶铜材质的，具有耐磨损的特性，使得阀门密封密封性好、耐磨性强、耐腐蚀、操作简单、安装方便、使用寿命长、适应性广等特点。

On the other hand, the more important thing is because the urban housing is a kind of heterogeneity products.

另一方面，更重要的是由于城市住房是一种异质性产品。
