2cr13不锈钢

 

2Cr13钢材从分类上来说应该是属于不锈钢,更精确的分类应该是归属于不锈铁,主要用于机械加工,比正常的不锈钢具有更好的性价比,因此在对耐腐蚀性要求不高的情况下,得到了更为广泛的应用。 2Cr13经过淬火处理后可以得到更好的机械性能,具有较好的可加工性,组织形态为马氏体型。

 
基本信息:

 

中文名称:2Cr13不锈钢

外文名称:2Cr13

分类:不锈钢

产地:国产

执行标准:国标GB14976-2007

主要用途:机械加工

 

简介:

2Cr13(新编号为20Cr13) 标准:GB/T 1220-2007

特性及适用范围: 淬火状态下硬度高,耐蚀性良好。用作汽轮机叶片。 2Cr13密度为7.75g/cm3 2Cr13淬火硬度:一般2Cr13的淬火温度在980~1050℃,取980℃加热油淬时硬度要明显低于1050℃加热油淬,980℃油淬后硬度为45~50HRC,1050℃油淬后硬度要高2HRC。但1050℃淬火后得到的组织晶粒较粗,脆性大。建议使用1000℃加热淬火可以得到较好的组织和硬度。2Cr13马氏体不锈钢,焊接要预热的。和Q235焊接用奥氏体不锈钢焊条不用预热,比如A302.A307都行。 焊接时控制焊缝稀释率,不摆动焊接,采用较小的电流。

2Cr13焊接焊材可以选用:

1.抗大气腐蚀选G202,G207,需预热150-300度,焊后回火700-730度;

2.耐有机酸并耐热选:G211,需预热150-300度;

3.良好塑性:A102,A107,A202,A207,A302,A307,补焊预热,厚大件预热。

热处理规范及金相组织

 

热处理

1)退火,800~900℃缓冷或约750℃快冷;

2)淬火,920~980℃油 冷;

3)回火,600~750℃快冷。

金相组织:组织特征为马氏体型。

 

交货状态:

一般以热处理状态交货,其热处理种类在合同中注明;未注明者,按不热处理状态交货。
