UHB 20C is a 1% carbon steel with high tensile strength and is often the standard choice for the medium and thinner range of flapper valves. It is hardened and tempered to a fine martensitic structure providing the highest fatigue strength in high carbon steels.
UHB 20C is an excellent choice for applications where corrosion resistance is not so critical and economical volume production of flapper valves is the main criteria, compared to our stainless flapper valve steels. It is frequently used in segments such as automotive air conditioning, refrigerators and household air conditioning.
UHB 20C is a 1% carbon steel developed for flapper valves in compressors.
» Highest fatigue strength among all carbon steels
