Experimental Study of Yellowing Index Comparison between 430 Stainless Steel and 441 Stainless Steel Burner Plates on Domestic Gas Hobs
Abstract
For the household appliances, one the critical design parameter is esthetic. On the surface of the
domestic gas hob burner plates, yellowness problem is seen with the high temperature flame effect. When the
burner plate surface is getting higher yellowness, esthetical problem is occurred. In this study, for evaluating
yellowness period and comparing the yellowness ratio, 6 hobs are tested and measured yellowing index by using
colorimetry method in Haier Europe Quality Reliability Laboratory. 3 of the 6 hobs have the 430SS burner
plate, other 3 hobs have the 441SS burner plate. During 360 cycles of hob working, 4 times yellowness is
measured in the beginning (cycle 0), then end of the 120,240 and 360. cycles. Each measurement is repeated 2
times on one area to increase accuracy of measurement. In the end of the study, results show that 441SS material
has lower yellow color changing than 430SS material as a burner plate in the same conditions.
