我厂用9Cr18不锈钢制造的耐腐蚀轴承,近些年来在轴承半成品和成品零件的检验中,曾经多次发现过有如图1所示的组织。这种组织在退火或淬火后均曾发现过。在基体组织上分布着呈链条状的(直线的或是网状的)碳化物,方向不一,严重程度不同。其它兄弟厂也曾先后发现过此种组织。 I plant with 9Cr18 stainless steel corrosion-resistant bearings, bearings in recent years, testing of semi-finished and finished parts, have repeatedly found the organization shown in Figure 1. Such organizations have been found after annealing or quenching. In the matrix organization is distributed in a chain of (linear or reticular) carbide, in different directions, the severity of different. Other brothers plant has also found such organizations.
