PROBLEM TO BE SOLVED: To provide a bonding method of a ferrous material capable of bonding at a comparatively low temperature, and suppressing deformation upon bonding.SOLUTION: A ferrous material is bonded by a bonding method of the ferrous material including an organic acid treatment step for boiling a surface including a bonding part of each ferrous material of a plurality of ferrous materials in an organic acid solution, or exposing it to steam containing an organic acid, and a bonding step for butting, heating, pressurizing and bonding each surface of the bonding parts of the boiled or exposed ferrous material .SELECTED DRAWING: Figure 1 【課題】比較的低温で接合が可能であり、接合時の変形を抑制することができる鉄鋼材料の接合方法を提供する。【解決手段】複数の鉄鋼材料の各鉄鋼材料の接合部を含む表面を、有機酸溶液中において煮沸する、又は、有機酸を含む蒸気に曝露する有機酸処理工程と、煮沸又は曝露された鉄鋼材料の接合部の表面同士を突き合わせて、加熱及び加圧して接合する接合工程を含んで、鉄鋼材料を接合する。【選択図】図１
