本考案は、高炭素鋼と低炭素ステンレス鋼とを
複合してなる、いわゆるステンレス複合刃物の構
造に関する。[Detailed Description of the Invention] [Technical Field] The present invention relates to the structure of a so-called stainless composite cutter made of a composite of high carbon steel and low carbon stainless steel.
かかるステンレス複合刃物は、表面の大部分が
ステンレス鋼であるため錆が生じ難い、再研摩の
時硬いのは高炭素鋼の部分だけなので、全体が高
炭素ステンレス鋼と比較して容易に研ぐことがで
きる、刃物製造時の焼入温度が高炭素鋼の鋼種に
よつて決められるから焼入が容易である、硬い高
炭素鋼が中心部全体に入つているため強度がある
等従来の黒打庖丁と比較して多くの利点があるこ
とが知られている。
Since most of the surface of such stainless steel composite cutlery is made of stainless steel, it is difficult to rust, and only the high-carbon steel part is hard when re-sharpened, so it is easier to sharpen the entire blade than high-carbon stainless steel. The quenching temperature during knife manufacturing is determined by the type of high-carbon steel, so quenching is easy.The hard high-carbon steel is contained throughout the center, making it stronger. It is known to have many advantages compared to a knife.
しかしながら、高炭素鋼と低炭素のステンレス
鋼とをクラツドするに当つては、炭素量に大きな
差があるため、加熱時に高炭素側の炭素が低炭素
側に吸収され、脱炭した状態になる。 However, when cladding high carbon steel and low carbon stainless steel, there is a large difference in carbon content, so when heated, the carbon from the high carbon side is absorbed by the low carbon side, resulting in a decarburized state. .
例えば、SK3とS10Cのクラツド鋼板では境界
のSK3は相当量脱炭しており、焼入後研磨してみ
ると、境界のSK3が雲がかかつた状態になり、硬
さが低下して切削性が悪くなるとともに、外観上
商品価値の面についても大きな問題となつてく
る。 For example, in a clad steel plate between SK3 and S10C, the SK3 at the boundary has decarburized to a considerable extent, and when polished after quenching, the SK3 at the boundary becomes cloudy and its hardness decreases, making it difficult to cut. As the quality deteriorates, the appearance and commercial value also become a big problem.

て、高炭素鋼と低炭素ステンレス鋼との間にニツ
ケルあるいはニツケル−銅合金の中間層を介在さ
せたものがあるが、この中間層は融点以下に加熱
し、圧延して接合されており、固相接合であるた
めに圧延中に剥離を生じる場合があり、刃物とし
ての製品歩留りが悪くなるという問題があつた。 Some stainless steel composite cutlery that does not have this carbon migration are made by interposing an intermediate layer of nickel or nickel-copper alloy between high carbon steel and low carbon stainless steel, but this intermediate layer is heated below the melting point. Since they are joined by rolling and are solid phase joined, peeling may occur during rolling, resulting in a problem of poor product yield as cutlery.
また、接合性を高めるために加熱温度を高める
と、炭素移動が行われ、硬さが充分でなくなると
いう問題が再び生じるということになる。 Furthermore, if the heating temperature is increased to improve bonding properties, carbon migration occurs and the problem of insufficient hardness arises again.
本考案の目的は、かかる中間層を介在させてな

おいて、接合性が改善されたにも拘わらず、硬さ

The purpose of the present invention is to provide a composite cutter made of high carbon steel and low carbon stainless steel with such an intermediate layer interposed therebetween, with a structure that does not reduce hardness despite improved bondability. It is in.

下の要領で行うことができる。 The high carbon steel that will be the base material 2 and the low carbon stainless steel that will be the composite material 3 do not need to be special steel types, and SK3 and SUS-304, which have been used in conventional composite cutlery, can usually be used. can. In addition, the Ni-B-Si brazing alloy used as the bonding material may have a melting point of 1000°C or less, such as B
An alloy consisting of 2.75 to 3.50% by weight, 4.0 to 5.0% by weight of Si, and the balance Ni (melting point 980°C) can be suitably used, and the bonding layer 4 after melt rolling cannot be confirmed macroscopically, but can be roughly seen in micrographs. A thickness of about 1 to 10 microns is sufficient, and with this, it is possible to obtain a metallurgically completely bonded layer, even though it is an extremely thin bonding layer, and to obtain a cutter with no carbon migration at all. . This melt-rolled bonding layer 4 can be formed in the following manner.
