1.4841 - AT A GLANCE
What kind of steel is the 1.4841?
The 1.4841, also know under its chemical discription X15CrNiSi25-21, is an austenitic, heat resistant stainless steel. The addition of sililcon, among other alloys, in the stainless steel 1.4841 makes this steel grade more resistant to oxidation and prevents carburization at elevated temperatures.
On the other hand, continuous use at a temperature range of 650 – 900°C makes this stainless steel more susceptible to phase changes and embrittlement. This material grade is suitable for cold forming and cold heading, hammer- and die forging and is not magnetizable.
Properties
The 1.4841 stainless steel is a good choice for high-temperature environments due to its high temperature resistance. It has good corrosion resistance in mild atmospheres and is relatively easy to form. As with all materials, the applications and desired properties should be considered when choosing the material.
- Heat resistant
- Chromium-nickel-molybdenum steel
- Resistant to oxidation at high temperatures
- Good strength properties
- Excellent chemical resistance at high temperatures up to 1100 °C
- Very good corrosion resistance
- Creep resistant at high temperatures
- Non-magnetizable
Applications
Stainless steel 1.4841 can be used at high temperatures up to 1100°C and is resistant to oxidation which makes it ideal for furnace components, ore processing and kiln components as well as heat treatment equipment like heat retorts and heat conductors.
In high temperatures the material does not go soft or brittle which is beneficial when using the 1.4841 in heat exchangers with aggressive atmospheres, high temperature oxidation and carburization.
The 1.4841 can resist creep (a deformation over an extended time at elevated temperatures and high, constant stress) in high temperatures and for extended periods.
