ものの、非磁性であるため車独では安全装置のついた電
磁調理器にかからない。(Function) Since ferritic stainless steel (hereinafter partially abbreviated as α-8US) is magnetic, it can be used in cooking equipment equipped with a safety device and has sufficient corrosion resistance. However, when used alone, the load is only 80% of the maximum output. On the other hand, although austenitic stainless steel (hereinafter abbreviated as 7-8US) has excellent corrosion resistance, it is non-magnetic and cannot be used in electromagnetic cookers equipped with safety devices.

１３層に、γ−３ＵＳを第２層にした場合は最高出力の
８０％しか負荷がかからない。Therefore, by using a clad steel plate with γ-8US as the first layer and α-8US as the second layer, it can be used in cooking equipment with a safety device, and the maximum output is 100%.
% load can be applied. Here, if α-3US is placed in the 13th layer and γ-3US is placed in the second layer, the load is only 80% of the maximum output.

。尚、α−８ＵＳ層の厚みはα５ｍｍとした。Table 1 shows that the first layer is γ-8US and the second layer is α-8US.
The composite material was placed in an electromagnetic cooker, and the first layer of γ-8US
This figure represents the ratio (■) of the output of the composite material to the maximum output for each thickness when the thickness of the composite material is changed. Note that the thickness of the α-8US layer was α5 mm.
第 １ 表
第１表かられかるように、γ−８ＵＳ層の厚さがＬＱ
ｍｎｌを越える場合は最高出力の１００％の負荷をかけ

If mnl is exceeded, 100% of the maximum output load cannot be applied.
また、第１層のγ−８ＵＳ層が薄すぎると器物に加工す

くはαＱ ５ ｍｍ以上とする。Furthermore, if the first γ-8US layer is too thin, there is a risk that the α-3US layer will be exposed during processing into objects, so the thickness is preferably αQ 5 mm or more.

定されるものではない。Further, by providing a γ-8US layer as a third layer inside the α-3US layer, corrosion resistance can be further improved. Additionally, since α-3US and γ-3US have different deformation resistances, the three-layer composite material described above has the advantage of being easier to roll during manufacturing compared to the two-layer composite material of α-8US and γ-8US. be. In this case, the thickness of the third layer is not particularly limited.
