Super Duplex

What is the difference between S32750 and S32760?

S32750 and S32760 are both super duplex stainless steels (SDSS). As such, their microstructure is a combination of austenitic and ferritic grains, which imparts the most favourable properties of each. They are based upon a 25% chromium content (25Cr), but differences in their mechanical properties, physical properties and composition are small.

What is SDSS?

SDSS is an acronym for Super Duplex Stainless Steel. A duplex stainless steel is a combination of a ferritic and an austenitic microstructure, and combines the most favourable properties of each.  There are a number of different SDSS available, as the family of alloys based upon a 25% chromium (25Cr) content has developed since the 1960’s.

What are the physical properties of Inconel 718?

Inconel® 718 (UNS N07718, DIN 2.4375) is often considered a super alloy on account of its strength at elevated temperatures.

What is the Impact Toughness of Duplex and Super Duplex Stainless Steels?

Impact toughness is the ability of a metal to withstand a suddenly applied shock load and is quantified by the amount of energy absorbed.

What is the ASTM G48 test?

ASTM G48 is a corrosion test used as a measure of pitting corrosion resistance of stainless steels.

What is the melting point of stainless steel?

As they are an alloy of several different metals, the melting point of stainless steel happens over a temperature range.
