とした耐摩耗合金が開発されている。Co-Cr-Ni-W alloys (commonly known as stellite) have traditionally been widely used as wear-resistant alloys, but recently they have been used from the viewpoint of depletion of cobalt resources, reaction control of chemical plants, or improving the safety of atomic couplants. Since then, wear-resistant alloys based on NI have been developed.

It has been found that the Riften-Tungsten-Ninogel alloy has the abrasion resistance required for the above-mentioned various plant grooving members.

ものである。The present invention is based on the above @mother-in-law, and the present invention is based on pulp face parts and jet pump parts in various plants and various machines.
The aim is to provide a wear-resistant alloy suitable for sliding parts and the like.

ルより成ることを＄１とするものである。In detail, the present invention will be described below. The wear-resistant alloy of the present invention is composed of 10-45% chromium, 3-15% niobium, 4-2% molybdenum (1), 2-6% tungsten, and the balance nickel. The amount shall be $1.

チを越えると合金の靭性の低下が与られるからである。The wear-resistant alloy of the present invention has a chromium-niobium-
Molybdenum-nickel system with a composition ratio of chromium 10
~45 layers, 3~15 layers of niobium, 4~ molybdenum
It is necessary to choose between 20 pieces of tungsten, 2 to 6 pieces of tungsten, and the rest of nickel.One reason for this is as follows. First of all, chromium is a necessary component for corrosion resistance and for shallowing the matrix of the alloy.If the composition ratio is less than 10%, the effect is insufficient, and if it exceeds 45%, coarse primary crystal phases will precipitate excessively. The required wear resistance cannot be obtained (8. Niobium is a component that reacts with nickel and contributes to strengthening the base of the alloy and improving wear resistance, but if less than 3 people contain niobium, the young fruit will fail. If it exceeds 15%, the toughness decreases and the mechanical strength of the material is impaired.Molybdenum improves corrosion resistance and hardens the alloy matrix, contributing to wear resistance. If the amount is less than 4'1, the effect is insufficient, but 20
This is because if the amount exceeds 1, the toughness of the alloy decreases.

However, if the amount is less than 2.0%, the effect will be insufficient, and if it exceeds 6.0%, the toughness of the alloy will decrease.

Furthermore, it may contain manganese, silicon, or the like as a denitrifying agent and a denitrifying agent added during melting.

! & When performing welding, the 18Cr-13Ni stainless steel plate is slightly affected by heat, but even if solution treatment is performed to remove this effect, the mechanical customization of the alloy of the present invention will not be affected. In addition, the present invention can be applied to the carbon shoulder plate (when overlay welding, a slight thermal effect is applied to the carbon cross plate, but in order to remove this effect, the present invention can be applied by subjecting it to austenitizing treatment, cracking and tempering). Alloy] Mechanical properties 4- are not affected.
