Corrosion-resistant alloys and high-temperature-resistant alloys have different application environments and compositions. The former is used in corrosive media and contains corrosion-resistant elements, while the latter is suitable for high-temperature and high-pressure conditions and contains high-temperature strengthening elements.
Selection of alloy
We always need to use some alloy in our lives, so how do we choose different performance alloys? In different use scenarios. We need to identify the similarities and differences between corrosion-resistant alloys and high-temperature alloys, to better choose the alloy that can perform well.
Oxidation resistance
Both corrosion-resistant and high-temperature-resistant alloys have good oxidation resistance and can be stabilized at high temperatures to maintain chemical stability.
Strength
Both typically have high strength and are capable of maintaining structural integrity under high stress and high-temperature conditions.
Wear resistance
Both corrosion-resistant and heat-resistant alloys typically have good wear resistance and are suitable for use in working environments with high friction or high-velocity conditions.

Differences between corrosion-resistant and high-temperature resistant alloy
Application environment
Corrosion-resistant alloys are mainly used in environments with corrosive media, such as the chemical industry, marine engineering, etc., while heat-resistant alloys are mainly used in high-temperature and high-pressure environments, such as aircraft engines and gas turbines.
Composition
Corrosion-resistant alloys usually contain corrosion-resistant elements, such as nickel, chromium, molybdenum, etc., to enhance their resistance to corrosive media; while high-temperature-resistant alloys usually contain high-temperature reinforcing elements, such as tungsten, molybdenum, titanium, etc., to improve their stability and strength under high-temperature conditions.
Temperature range
Corrosion-resistant alloys are generally used at lower temperatures, usually in the range of room to medium temperatures; while high-temperature-resistant alloys can work stably at higher temperatures, even up to thousands of degrees Celsius.
Production process
Due to different application environments and compositions, corrosion-resistant alloys and high temperature-resistant alloys may adopt different production processes and processing methods to meet their performance requirements.
