The Super Duplex 32750 is a super duplex stainless steel with incredible corrosion resistance, superior to that of ausenitic and duplex stainless steels in almost all corrosive media.
It combines the desirable aspects of both austenitic and ferritic grades, and includes higher chromium, molybdenum and nitrogen contents, resulting n a Pitting Resistance Equivalent Number (PREN) of >40.
Founded in 1938 and growing steadily throughout the Second World War, we at Langley Alloys take great pride in our successful alloy developments.
We supply a family of unique products to demanding applications, each with a proven track record of application in the chemical, aerospace and major defence industries. In fact, we’ve been involved in defence for a while – with our Hidurel 5 copper bearing alloy used in the engines of the incredible Spitfire aircraft.
In more recent years, we have opened sites in the United States and Singapore, providing a global reach and us with the ability to support our customers wherever they may be.
Our range of Super Duplex stainless steels, including the Super Duplex 32750 are twice as strong as austenitic or ferritic stainless steels.
Their addition of copper results in additional corrosion resistance, and it has been shown that the presence of copper can inhibit the formation of pitting corrosion.
They are a cost effective option for a number of demanding applications – due to their exclusion of high nickel additions.
