摘要
钢中的残余有害元素致使钢材产生红脆性表面裂纹和具有回火脆性倾向,并使耐热钢的热强性降低。因此,应从源头就对残余有害元素加以有效控制,并对钢材产品中残余有害元素限量制定内控标准,从而提高钢材产品的质量。
The residual deleterious elements in steel lead to the products occurring red surface brittleness crack and temper brittleness,and lead to the hot strength of heat resistant steel decreasing.So it is necessary to control the residual deleterious elements from materials and to set the standard of the residual deleterious elements in steel products to promote the quality of steel.
