耗という。The present inventors ordered a large number of worn and damaged loom members and actually used fibers, and investigated the worn and damaged parts and fibers from a microscopic viewpoint. As a result, in most of the worn members, flaws as if they were ground into thin lines were observed in the worn portions. Further, adhesion of hard particles such as alumina and silicon carbide was detected on the fibers used. From the scratches and the attachment of the hard particles as if they were ground, it was found that the wear phenomenon at this time was abrasion mediated by the hard particles.
In the present specification, wear in which hard particles are interposed on the contact surface between the fiber and the loom member and the contact surface of the loom member is rubbed or ground by the hard particles or the like in a vibration or sliding process is referred to as abrasive wear.

なかった。[0006] Abrasive wear is the most severe wear among various wear phenomena, and it is desired to develop a material that can withstand such wear. As a method of improving the wear resistance, a method of quenching a steel material having an increased carbon content to increase the strength was studied. As the quenching hardness increases, the amount of abrasive wear slightly decreases, but no remarkable wear suppressing effect is exhibited, and it is found that wear resistance cannot be significantly improved by strengthening the structure by adding carbon. The material hardened by cold working could not improve the abrasion resistance similarly to the structure strengthening material.

用は少ないものと考えられる。[0007] The fact that the resistance to abrasive wear cannot be enhanced by strengthening the structure or working hard means that hard particles such as alumina and silicon carbide are very hard and harder than the hardness obtained by strengthening the structure and hardening work. It is presumed that there is a cause. That is, the hardness obtained by the structure strengthening, work hardening and the like is very small compared to the hardness of hard particles such as alumina and silicon carbide, and it is considered that the effect of suppressing abrasive wear is small.

に抑制されることが判った。In the course of elucidating the wear mechanism and investigating materials capable of withstanding wear, it has been found that when hard carbide is dispersed and precipitated in a steel matrix in a predetermined amount or more, the wear resistance is dramatically improved. Specifically, T is a carbide having almost the same hardness as hard particles such as alumina and silicon carbide.
Focusing on the carbides of i and Nb, the relationship between the amount of precipitation of these carbides and the wear resistance to abrasive wear was investigated.
As a result, it has been found that even if the materials have the same hardness, the abrasive wear is effectively suppressed when carbides of Ti and Nb are dispersed and precipitated.

コストの上昇を招く。The steel material to which the present invention is applied contains 8.0 to 35.0% by weight of Cr for imparting corrosion resistance.
When the Cr content is less than 8.0% by weight, the anticorrosion effect due to the addition of Cr is reduced. However, if an excessive amount of Cr exceeding 35.0% by weight is contained, the hot workability is reduced and the production cost is increased.

5 to 1.0% by weight, Nb: 0.05 to 1.50% by weight alone or Ti + Nb: 0.05 to 2.0% by weight in total
At a rate of The total carbide precipitation of 0.1% by weight or more is a critical value found from the investigation of the effect of precipitated carbides on abrasion resistance, as described in Examples below, and 0.3% by weight or more. By ensuring the total amount of precipitation, abrasion resistance which is much more excellent than that of a steel material having no carbide can be obtained. Ti: 0.05% by weight or more, Nb: 0.
When the content is set to at least 05% by weight or at least 0.05% by weight of Ti + Nb, the total amount of carbides dispersed and precipitated in the matrix becomes at least 0.1% by weight. However, excessive addition of Ti deteriorates the flow of molten metal during smelting and casting, and excessive addition of Nb precipitates as an intermetallic compound and lowers toughness. The upper limit of the content was set to 1.50% by weight, and the upper limit of the total content of Ti + Nb was set to 2.0% by weight.

Carbon is an alloy component that is not only consumed in the formation of carbides but also effective in strengthening the structure. However, when the C content exceeds 1.20% by weight, a large amount of giant eutectic chromium carbide precipitates, which deteriorates quality, hot workability and the like.

After heating and holding at 1050 ° C. for 1 minute in a non-oxidizing atmosphere furnace, the mixture was air-cooled to room temperature. The carbides dispersed and precipitated on the test specimen were quantitatively analyzed, and the wear resistance and corrosion resistance against abrasive wear were investigated. The amount of carbide precipitation is
The test piece whose amount of carbide was controlled by the precipitation treatment was immersed in an iodine alcohol solution, ultrasonic waves were applied to dissolve the steel material, and then the amount was determined from the amount of carbide remaining in the solution.

The contact was slid under the condition of 0 hour, and the wear depth of the contact portion was measured. Then, the wear amount of the mail part worn by contact with the fiber is obtained, and the wear depth D of the stainless steel SUS420J2 is obtained.

In order to obtain a wear characteristic twice or more, abrasion resistance of M ≦ 50% is required. Regarding the corrosion resistance, the test piece was subjected to a test in which 5% salt water was sprayed for 72 hours, and then the surface of the test piece was observed to check for the occurrence of rust.

This indicates that 8% by weight or more of Cr is necessary to ensure corrosion resistance. In Test Nos. 8 to 10 in which the total precipitation amount of titanium carbide and niobium carbide is less than 0.3% by weight, the index M is not significantly reduced as compared with Test No. 11 (conventional material). On the other hand, in Test Nos. 1 to 7 (examples of the present invention) in which the total amount of precipitation was 0.3% by weight or more, the index M was less than 30%, and the life span was more than three times that of the conventional flood heald. It turns out that it has.

As is clear from FIG. 1, the index M decreased when the total amount of carbide precipitated increased, and the index M sharply decreased when the total amount of carbide became 0.1% by weight or more. When the total amount of precipitated carbides was adjusted to 0.1% by weight or more, the index MC became 50% or less, and it was found that a flood heald having a life twice or more as long as the conventional material was obtained.

By dispersing and precipitating in the matrix at a ratio of 3% by weight or more, much superior wear resistance is imparted as compared with a structure strengthening material by quenching or a working strengthening material by cold working or the like. For this reason, it is used as a long-life loom member such as a flood heald, a dropper, a reed, a deformed reed, a lead, etc., which are worn by contact with the fiber.
