What’s Ariron

The Ariron, in the iron-based alloy cast iron containing 14% or more of silicon, as an excellent acid-resistant material with a wide range of adaptability and long-term corrosion resistance, come to be widely used in the chemical industry district of the chemical industry today progress, has contributed greatly to the development. Its name is a registered trademark, which was derived from the “Acid-Resistant IRON”, has been used for the pronoun of acid and high silicon cast iron products in Japan.

Features of Ariron

1. Ariron is hydrofluoric acid, a number of inorganic acids other than the high-temperature concentrated hydrochloric acid and high-temperature alkaline, very well tolerated in the organic acid and various salts solution, even in the heat and high temperature condition indicates a stable acid resistance. In particular, any concentration for the sulfuric acid, and exhibits acid resistance to temperature.

2. Hardness is high, so is excellent in wear resistance, corrosion resistance of the chemical solution containing the slurry component is good.

3. Pitting corrosion, such as such as those found in stainless steel, intergranular corrosion, since there is not subject to local corrosion, such as cracks, can be used as a very stable and acid-resistant material.

Precautions against Ariron product

1. Ariron, since the organization is made from ferrite and fine graphite, be heated less oxidation and growth, you can fully use even at high temperatures. However, a large thermal expansion coefficient, since the thermal conductivity and tensile strength is small, there is a possibility that a crack may occur when performing the rapid heating and cooling.

2. Very strong in compression, is safe in case of receiving a static compressive load, but because weak to mechanical impact, tensile load, bending load, such as careless hammering or uneven tightening of working results in a damage caused You may.
