狀態 抗拉強度rm n/mm2 屈服強度rp0.2 n/mm2 延伸率 a5 % 布氏硬度 hb
固熔態 690 380 35 ≤241
特性：
與含鈷和高鎳合金相比， 不銹鋼能以極低的成本實現抗腐蝕和耐磨損。其整體抗腐蝕性優于大多數介質中的 304 型。在中，抗氯化物點蝕的能力優于 316 型。
室溫下的屈服強度幾乎是 304 和 316 的兩倍。具有---的抗高溫氧化性和抗低溫沖擊性。
應用領域：
廣泛應用于電力、化工、石化、食品和油氣工業，包括伸縮接頭耐磨板、耐磨泵環、襯套、工藝閥桿、密封件和測井裝備。

solid melting state 690 380 35 ≤241
features:
corrosion&wear resistance can be achieved with stainless steel at very low cost compared to cobalt-containing&high-nickel alloys. its overall corrosion resistance is better than that of type 304 in most media. the resistance to chloride pitting is better than that of type 316.
the yield strength at room temperature is almost twice that of 304&316. excellent resistance to high temperature oxidation&low temperature impact.
application areas:
widely used in the power, chemical, petrochemical, food&oil&gas industries, including telescopic joint wear plates, wear pump rings, bushings, process stem, seals&logging equipment.
