非金属众盈彩票登陆夹杂物尺寸大于50μm时,降低了钢的塑性、韧性和疲劳寿命,使钢的冷热加工性能乃至某些物理性能变坏。一般我们钢水中夹杂物尺寸都为大于50μm。大型夹杂物不利用钢板韧性、塑性以及强度指标。除了这些性能外,还有降低抗酸性能、疲劳性能、表面光洁度以及焊接性能。

钢中非金属夹杂物是导致钢耐腐蚀性能降低的重要原因。非金属夹杂物与基体钢之间有不同的化学位,与基体钢之间易形成微电池,一旦有环境腐蚀介质存在,就会产生电化学腐蚀,形成腐蚀坑和裂纹,严重者会导致破裂失效。

影响氢致开裂的因素很多,但是对某一特定钢种来说,除去工艺因素的影响外,夹杂物的影响是主要的。夹杂物是氢的强陷阱,非金属众盈彩票登陆夹杂物(特别是长条状的MnS)周围氢压很高,夹杂物与基体界面的结合强度相对较弱,随着氢压增大会在夹杂与基体界面萌生裂纹。氢致裂纹在夹杂物处形核概率较大。夹杂物级别越多,数量越高时,导致氢致开裂的敏感性越大。
