Price of High Pressure Reactors changes with the material of construction

For reactors like Parr Instruments and Autoclave Engineers the choice of material is critical.

Stainless steel and Hast C ( Hastelloy C276) are two common materials used in the construction of chemical reactors. While both materials are durable and resistant to corrosion, they have different properties that make them better suited for certain applications.

Stainless steel is a type of steel that contains chromium, which makes it resistant to corrosion and staining. It is commonly used in the construction of chemical reactors because of its strength and durability, and its ability to withstand high temperatures and pressures. Stainless steel is also easy to clean and maintain, which makes it a popular choice for applications where hygiene is important.

On the other hand, Hast C is a nickel-based alloy that contains chromium, molybdenum, and tungsten, which makes it highly resistant to corrosion and oxidation. Hast C is commonly used in the construction of chemical reactors that handle corrosive materials, such as acids and bases. Its resistance to corrosion also makes it ideal for use in high-temperature and high-pressure applications.

One of the key differences between stainless steel and Hast C is their resistance to corrosion. While stainless steel is resistant to corrosion, it is not as resistant as Hast C. Hast C is specifically designed to resist corrosion, even in highly corrosive environments. Additionally, Hast C has a higher strength and toughness than stainless steel, which makes it more durable and resistant to wear and tear.

Another difference between stainless steel and Hast C is their cost. Hast C is more expensive than stainless steel, due to its higher nickel content and the additional elements used to make it corrosion-resistant. This can make it more cost-effective to use stainless steel in applications where corrosion resistance is not as critical.

In conclusion, while both stainless steel and Hast C are commonly used in the construction of chemical reactors, they have different properties that make them better suited for certain applications. Stainless steel is ideal for applications where strength, durability, and ease of maintenance are important, while Hast C is ideal for applications where resistance to corrosion is critical. Understanding these differences can help chemical engineers choose the best material for their specific application.
