What is stainless heat-resistant steel used for?

Heat-resistant steels are highly versatile. They are primarily used in sheet steel form but also as round steel or steel pipe, for example for the following products or industries:

Rotary kilns in the cement industry
Nitric acid tanks in the food industry
Pipelines in oil and natural gas processing plants
Industrial furnaces and waste incineration plants
Automotive exhaust pipes
Hot water storage in energy supply

What are the properties of stainless heat-resistant steel?

Heat-resistant steel is available as austenitic or ferritic steel as well as duplex steel, a mixture of both structures. Depending on the type of microstructure, different properties arise. For example, austenitic steels have low heat and temperature conductivity, but are more sensitive to thermal fatigue.

The most important basic characteristics are:

High fatigue strength/creep resistance in the desired temperature range
Resistance to corrosion including water corrosion, high temperature corrosion and sulphurous media
Very good resistance to carburisation
Stable microstructure
High mechanical load capacity

What makes stainless steel resistant to heat?

In contrast to conventional stainless steels, heat-resistant steel grades have an increased content of chromium, aluminium and silicon. This leads to the formation of an impermeable oxide layer, which provides an exceptional degree of heat resistance and as such resistance to permanent scaling caused by exhaust gases.
