Is Inconel Stronger Than Stainless Steel?

Is Inconel Stronger Than Stainless Steel?

Inconel and stainless steel are like the two sides of a coin. What we mean to say is, a consumer must choose either of the ones!

We need to undertake various factors like scope of work, operating temperature, physical environment, fabrication process, etc., before manufacturing a new part. It will help a person to produce and install the correct metal for application(s) in their industrial premises.

While comparing stainless steel and Inconel, it is crucial to understand that each grade of the metals undergoes a different formulation process.

For instance, grade 625 Inconel has a higher resistance to chloride than 304 stainless steel due to the difference between their chemical and mechanical properties.

Sometimes our clients are uncertain about which metal will suit their requirements. Although Inconel and stainless steel might look similar, they are relatively different in terms of strength. The strength depends upon tensile strength, corrosion resistance, and melting points of the metals.

We are presenting you with five different factors which will help you to know the difference between Inconel and stainless steel in relevance to strength:

TENSILE STRENGTH

Tensile strength is the maximum load a metal can resist in extreme environments without being fractured or tempered. Technically, the tensile strength of Inconel is higher than that of Stainless Steel. Inconel exhibits high-temperature tolerance, even at 2000-Degree F than other metals.

OPERATING TEMPERATURE

Operating temperature is the temperature range in which machinery or piping systems can function smoothly. Usually, the Inconel metal can perform better in higher operating temperature areas than the stainless steel. During the heat-generating process, a passivating oxidizing layer forms on the Inconel surfaces, preventing corrosion and further damages.

CORROSION RESISTANCE

Corrosion Resistance refers to the protection of the materials against uncertain reactions, which can corrode them instantly. Inconel provides resistance to oxalic acids and high-temperature oxidations. On the other hand, Stainless Steel exhibits excellent overall resistance to high-chloride areas.

MELTING POINT

Melting point refers to the temperature at which a given metal will melt. The melting point of stainless-steel ranges from 2550-Degree F to 2650-Degree F, which is technically higher than Inconel metal (2350-Degree F to 2460-Degree F). Since Inconel exhibits higher resistance to oxidation and scaling thus, the melting point of Inconel is comparatively low.


COST

The cost of Inconel is slightly higher than stainless steel. Inconel provides better tensile strength, stability, and durability in high-temperature areas. On the other hand, stainless steel helps create domestic appliances like kitchen accessories, cookware, cutlery items, etc., which makes them affordable.

FINAL THOUGHTS

At high temperatures, Inconel has much better resistance to corrosion, stress, and pressure compared with stainless steel. We understand that the key determining factor is always the cost for a consumer. However, we recommend you consider the factors discussed above while deciding between the two different alloys.
