What is the difference between sheet and plate?

A sheet is a thinner item of metal cut from a continuously rolled coil, whereas a plate is a thicker item rolled as a single piece.

What is the difference between the various super duplex alloys?

There are subtle composition differences between super duplex grades, but Ferralium is the only one to exceed a min. yield strength of 85ksi.

How has Ferralium developed over the years?

Improvements have been made to the composition, reducing impurities and associated inclusions, plus improved heat treatment.

How was Ferralium developed?

Ferralium is the original super duplex stainless steel, developed by Langley Alloys throughout the 1960’s and a patent in 1967.

What is the difference between 304 and 316?

Alloy 316 offers improved corrosion performance over Alloy 304, by virtue of an increased molybdenum content.
