请问谁知道1Cr17Ni2不锈钢可用什么材料代替啊、

1cr13 都是蘸火的

1CR17NI2棒材抗剪强度是多少,查不到

1Cr17Ni2抗拉强度σb (MPa):淬火回火,≥1080

1Cr17Ni2是国标老牌号马氏体不锈钢,执行标准:GB /T 20878-2007 

1Cr17Ni2系是马氏体不锈钢中强度与韧性搭配较好的一种钢种。它对氧化性酸、大部分有机酸以及有机盐类的水溶液有良好的耐蚀性。一般适用于制造硝酸,醋酸的生产和轻工,纺织等工业中的既要要求强韧性又耐腐蚀的轴,活塞杆,泵等零件。

1Cr17Ni2是什么材料

1Cr17Ni2钢属于马氏体型不锈耐酸钢,具有较高的强度和硬度。此钢对氧化性的酸类(一定温度、浓度的硝酸、大部分的有机酸),以及有机酸水溶液都有良好的耐腐蚀性能,适宜制造在腐蚀介质作用下的塑料模具和透明塑料制品模具等。但该钢焊接性能不好,易产生裂纹,制造模具时,不宜进行焊接。

1Cr17Ni2钢是低碳铬镍型耐蚀钢, 具有较高的强度和硬度。对氧化性的酸类 (一定温度、浓度的硝酸、大部分的有机酸), 以及有机酸水溶液都有良好的耐蚀性. 亚温淬火能有效地抑制该钢的高温回火脆性。可以使钢的脆性转化温度降低, 韧性得到改善, 断口形貌由准解理型变为韧窝型, 合金元素向基体和δ-铁素体中的富集程度增大,在改善钢韧性的同时仍保持较高的强度水平。但该钢焊接性能不好, 易产生裂纹, 因此制造具时, 不宜进行焊接。

当锻造加热温度较高时, 虽然钢的α-相增多, 但塑性良好, 这与部分组织强烈的再结晶有关。该钢在1100°C时的伸长率更大。为了改善钢的塑性和表面质量, 应使停锻、停轧温度偏高一些; 同时, 为了得到均一的组织, 应该采取较大的锻造比。
