含Nb高Cr-Ni铸造不锈钢的耐磨蚀性能随稳定化处理时间的延长而下降,而当稳定化处理时间超过6h后,其耐磨蚀性能明显提高。钢的耐磨蚀性能与耐腐蚀性能有一定的对应关系。钢的耐腐蚀性能、硬度、耐腐蚀性能均与组织中析出相的性质和数量有关。
The abrasion resistance of Nb-containing high Cr-Ni cast stainless steel decreases with the prolongation of stabilization treatment time, and its corrosion resistance obviously increases when the stabilization treatment time exceeds 6h. Steel abrasion resistance and corrosion resistance have a certain corresponding relationship. Corrosion resistance of steel, hardness, corrosion resistance and the nature of the organization and the number of precipitation phase.
