回答1:

一、1.4460产品简介
EN 1.4460是一种耐酸奥氏体铁素体钢,其特征是:
优异的抗点蚀、缝隙腐蚀、应力腐蚀和腐蚀疲劳性能
高强度
卓越的可加工性
高韧性


二、1.4460材料标准
EN / DIN:X3CrNiMoN27-5-2 - 1.4460
AFNOR:Z 5 CND 27-05 Az - Z5CND27-05 Az
UNS ASTM:AISI 329 - S32900
UNS ASTM:J93371 - 25Cr-5Ni-Mo-N - CD6MN - A 781 Grade 3A
UNE:X8CrNiMo26-6 - X 8 CrNiMo 26-6 - F-3552
SS:2324
三、1.4460可供形状
棒材,板材,锻件,管材【现货价格查询】
四、1.4460成份含量

碳 C    ≤0.05    铬 Cr    25-28    

硅 Si    ≤1.00    镍 Ni    4.5-6.5    

锰 Mn    ≤2.00    钼 Mo    1.3-2.0    

磷 P    ≤0.035    氮 N    0.05-0.20    

liu S    ≤0.030              

 
五、1.4460机械性能
固溶退火条件值符合EN 10088-3

抗拉强度 Rm    620 - 880N/mm2    

屈服强度 Rp02    ≥460N/mm2    

伸长率 A5%    ≥20    

冲击能量 KV –RT    ≥85 J/cm2    

硬度HB    ≤260    

 
六、1.4460物理特性
密度kg/dm3:7.8
弹性模量GPa:200
七、1.4460应用领域
螺旋桨轴系
主轴
泵轴系
搅拌器
泵部件
螺栓连接
阀门部件
螺母螺帽
活塞
八、1.4460耐腐蚀性
EN 1.4460显示出很好的耐腐蚀性,特别是在含氯环境中。其抗点蚀、缝隙腐蚀、应力腐蚀和腐蚀疲劳等氯离子腐蚀性能明显优于EN 1.4404型全奥氏体不锈钢。
在大多数情况下,在还原酸和氧化酸的一般耐腐蚀性方面,EN 1.4460比EN 1.4404型要好得多。此外,在500-900℃的温度区间内,两相组织和低碳含量使EN 1.4460在敏化后具有更好的抗晶间腐蚀性能。
当对耐点蚀性和缝隙腐蚀性要求极高时,建议钢表面加工后进行酸洗或钝化。
九、1.4460热处理
固溶退火1020-1100℃。固溶退火温度保持时间约30分钟,然后在水中快速冷却。在特殊情况下,应力消除可在550℃-600℃下进行。
十、1.4460冷热成型
热成形应在1200-950°C的温度范围内进行。但是,应注意双相材料在高温下的强度较低。
热加工后通常应进行固溶退火。
由于双相材料具有很高的抗弯强度,双相钢冷成形通常需要比奥氏体钢更大的工作力。由于屈服点高,回弹率相对较高。通常建议在冷变形超过10%后进行固溶退火。

1.4460对应相当于我国022Cr25Ni6Mo2N牌号,SS329是日本牌号,选用配套焊材:ER2594焊丝,E2594焊条。
根据国家标准GB/T 20878-2007“不锈钢和耐热钢 牌号及化学成分”标准附表B.1序号第73号,1.4460为欧洲标准EN10088.1-1995、EN10095-1999和国际标准ISO/Ts15510:2003、ISO4955:2005中的X3CrNiMoN27-5-2牌号,美国标准ASTM A959-01中的S31200牌号。该牌号相关资料如下:
1.化学成分(%)
C Si Mn P S Ni Cr Mo N
≤0.030 ≤ 1.00 ≤2.00 ≤0.030 ≤0.030 5.50~6.50 24.00~26.00 1.20~2.50 0.10~0.20

回答3:

1.4460(X3CrNiMoN27-5-2)是德标双相钢牌号,执行标准:EN 10088-1-2005

1.4460综合了许多铁素体钢和奥氏体钢最有益的性能, 由于该钢铬和钼的含量都很高,因此具有极好的抗点腐蚀,缝隙腐蚀和均匀腐蚀的能力.双相显微组织保证了该钢具有很高的抗应力腐蚀破裂的能力,而且机械强度也很高。应用于石油和天然气工业;海上石破天油平台(热交换器管,水处理和供水系统,消防系统,喷水系统,稳水系统; 石油化工设备; 脱盐(淡化)设备(和设备中的高压管,海水管);既需要高强度同时又需要高耐腐蚀性的机械和结构部件;燃(废)气净化设备.
