Description

Nickle Alloy Stem UNS S32760 Super Duplex F55 1.4501 Valve Disc Connect Actuator

Nickle Alloy Valve Stem is an important component of the valve, used for transmission. It connects to the actuator or handwheel at the top and directly drives the valve core to move or rotate at the bottom, thereby achieving the function of opening, closing, or regulating the valve.

Product Features:

The valve stem is not only a moving part and a load-bearing component during the valve opening and closing process, but also a sealing element. It is subjected to the impact and corrosion of the medium, as well as friction with the packing. Therefore, when selecting the valve stem material, it is necessary to ensure that it has sufficient strength, good impact toughness, anti-scoring properties, and corrosion resistance at the specified temperature. The valve stem is a wearing part, and attention should also be paid to the material’s machinability and heat treatment properties when selecting it.

UNS S32760 / 1.4501 / F55:

Material to UNS S32760 (and the other specifications listed below) is described as a super duplex stainless steel with a microstructure of 50:50 austenite and ferrite. The steel combines high mechanical strength (typically up to 600 MPa yield strength) and good ductility with outstanding corrosion resistance to marine environments and a wide, diverse range of oil & gas production environments. The alloy is supplied with a PREN (Pitting Resistance Equivalent) at >= 40.0 which guarantees high
resistance to pitting corrosion. In addition, the steel offers high resistance to crevice corrosion and stress corrosion cracking. Ambient and sub-zero (down to minus 50 °C) notch ductility is good. These attributes mean that this super duplex steel can be used successfully as an alternative to 300 series stainless steel (such as type 316), standard 22% Cr duplex steel and precipitation hardening stainless steels. Where appropriate the alloy can be considered in lieu of more costly Grade 5 titanium or
nickel based alloys.
