酸ナトリウム、チオ硫酸ナトリウム、二酸化マンガン。When stainless steel is immersed in a chemical conversion treatment solution containing oxalic acid and a suitable reaction accelerator, an insoluble chemical conversion film is deposited on the stainless steel surface. The film composition is mostly crystalline oxalic acid.
It is dominated by iron (FeCz 04 ) (approximately 98%)
It is said that when an iodine compound is used as a reaction accelerator, an insoluble iodine compound is produced, which acts as a lubricant during processing. In addition, sodium sulfite, sodium thiosulfate, and manganese dioxide are used as reaction accelerators.

。Sodium chlorate, fluoride, etc. are used. In addition to oxalate coatings, phosphate coatings are also known as chemical conversion coatings for steel materials.
It is virtually impossible to form a film on steel containing r: 10% or more. Therefore, for stainless steel containing 12% or more of Cr, the oxalate method is used rather than the phosphate method.

できなくなる。Table 1 (Composition of Barker liquid) [Problems to be solved by the invention] However, in the chemical conversion film formation treatment in actual operation, it is necessary to treat stainless steel materials of various types, sizes, and amounts, and the treatment liquid There was a problem that bath management was difficult. In other words, it is desirable to maintain the composition of the treatment liquid at the state at the start of the chemical conversion treatment at all times even during operation, but depending on the type of treatment, there is an appropriate composition range (A + ,
Not only do the mixing ratios of A 2 and A CIa differ, but also the consumption status of each composition differs for each product, as well as chemical reactions between the bath components, so it is necessary to gradually balance the composition as the continuous treatment progresses. The anti-seizure effect of the oxalate film cannot be exerted as desired.

た浴管理とならざるを得ない。On the other hand, since each component is used in a completely mixed state, it is difficult to quickly and accurately analyze the concentration of each component in the chemical conversion treatment solution, so it is necessary to accurately track and understand the fluctuations in the composition balance described above and optimize it. It is not possible to correct the balance, and at most the oxalic acid component concentration (for example, the above-mentioned AI) can be estimated by intermittent indirect measurements. Therefore, although it is possible to manage the bath to some extent by replenishing the concentration of the oxalic acid component, bath management for other components must rely on experience and intuition.

テンレス鋼を冷間加工する方法を提供することにある。The present invention was made against this technical background, and its purpose is to create a chemical conversion coating on stainless steel that can maintain good seizure resistance even if the compositional balance of the chemical conversion treatment liquid is slightly different. It is an object of the present invention to provide a chemical conversion treatment liquid that can be formed on the surface of steel, and to provide a method for cold working stainless steel using such a chemical conversion treatment liquid.

The gist is that phosphoric acid is contained so that the amount is .6 g/x. In addition, if a chemical conversion film is formed on the surface of stainless steel using the chemical conversion treatment liquid prepared as described above, the anti-seizure property will be good even if the composition balance of the chemical conversion treatment liquid may be slightly different. The formation of a chemical conversion film ensures good cold working of stainless steel.

た。[Function] The present inventors have conducted extensive research from the viewpoint that if the seizure resistance of the chemical conversion coating in the oxalate method can be improved, the above-mentioned problems arising from the difficulty of bath management may be alleviated. . As a result, the phosphate ion concentration in the chemical conversion treatment solution containing oxalic acid (for example, the Barker solution) is 0.03 to 0.8.
It was discovered that the seizure resistance of the chemical conversion coating could be improved by adding phosphoric acid to give a chemical conversion coating of 8711, and the present invention was completed based on this finding.

ある。また鉄鋼材料（Ｎｉ＜５％。Although the principle by which the seizure resistance of a chemical conversion coating is improved by including a predetermined amount of phosphate ions in the chemical conversion treatment solution has not been fully elucidated, it can be considered as follows. That is, phosphate ions in the chemical conversion treatment solution react with iron ions eluted from the stainless steel to form stable iron phosphate, which is deposited in the chemical conversion coating. This iron phosphate has good pressure resistance and is thought to contribute to improved anti-seizure properties. It should be noted that the conventional Parker solution also contains a trace amount of phosphate ion, but the concentration is 0.01.

This is, so to speak, a zinc phosphate chemical conversion method, and the phosphate ions contained in this treatment liquid are approximately 12 to 16 g/i.

成皮膜強度の低下が生じる。The phosphate ion concentration in the chemical conversion treatment solution of the present invention is 0.03
It is necessary to set it in the range of ~0.8 g/i, and this is due to the following reasons. That is, the phosphate ion concentration is 0.03
If it is less than g/jZ, the amount of iron phosphate produced in the chemical conversion coating is small, so no significant improvement in seizure resistance is observed compared to when no phosphoric acid is added. On the other hand, when the phosphate ion concentration exceeds 0.6 g/J:l, the strength of the chemical conversion coating decreases due to excessive phosphoric acid.
