特性：
与含钴和高镍合金相比， 不锈钢能以极低的成本实现抗腐蚀和耐磨损。其整体抗腐蚀性优于大多数介质中的 304型。在中，抗氯化物点蚀的能力优于 316型。
室温下的屈服强度几乎是 304 和 316 的两倍。具有出色的抗高温氧化性和抗低温冲击性。
应用领域：
广泛应用于电力、化工、石化、食品和油气工业，包括伸缩接头耐磨板、耐磨泵环、衬套、工艺阀杆、密封件和测井装备。

Features:
Corrosion and wear resistance can be achieved with stainlesssteel at very low cost compared to cobalt-containing andhigh-nickel alloys. Its overall corrosion resistance is better thanthat of type 304 in most media. The resistance to chloride pittingis better than that of type 316.
The yield strength at room temperature is almost twice that of304 and 316. Excellent resistance to high temperature oxidation andlow temperature impact.
Application areas:
Widely used in the power, chemical, petrochemical, food and oiland gas industries, including telescopic joint wear plates, wearpump rings, bushings, process stem, seals and logginge
