Stainless Steel - High Temperature Resistance Stainless steels are often used when high temperature oxidation resistance or hot strength are required. Reasons for this including scaling resistance, creep strength, structurla stability, environmental factors and thermal expansion are covered. High-Temperature Application Plating Another challenge when using metals in high-temperature environments is corrosion. High-temperature corrosion does not require a liquid electrolyte. Instead, the metals react with atoms in the atmosphere surrounding them. This reaction can occur at temperatures above approximately 1,200 degrees Fahrenheit.
Glass is characterized by a high degree of corrosion-resistance. Because of its high water-resistance it is often used as primary packaging material in the pharma industry since most medicines are preserved in a watery solution. Besides its water-resistance, glass is also robust when exposed to certain chemically aggressive liquids or gases. High-temperature corrosion Sandvik Materials Technology Materials for high-temperature service can not be selected on the grounds of their corrosion resistance alone. Their creep strength and structural stability also need to be taken into account. High-temperature corrosion testing. In Sandvik's high-temperature corrosion laboratory, testing is mainly performed in air (dry or humid). High Temperature Corrosion - an overview | ScienceDirect Topics High-temperature corrosion in the gas side occurs particularly in the superheaters and in the furnace but also elsewhere when the flue gas temperature is higher than about 500C. High-temperature corrosion is often caused by a combination of problematic ash deposits and corrosive gaseous compounds.
Ceramic coatings can be found sub-sea, in your engine compartment and everywhere in between. High temperature ceramic coatings provide a unique blend of hardness, corrosion resistance and heat resistance. Some formulations are stable up to 2000F and require only an ambient cure.
