What is the difference between a welded tube and seamless tube?

A welded tube will contain at least a longitudinal weld running the length of the tube where the edges of a formed flat sheet are joined.

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 are some signs of alloy corrosion?

Corrosion is a form of chemical reaction which will form a visible corrosion product.

What is localised corrosion?

Localised corrosion occurs in specific locations rather than across the entire exposed surface.

What is General Corrosion?

General (or uniform) corrosion is the most common form of corrosion, where corrosion occurs across most of the surface area of the metal.

What are the main types of corrosion?

There are many different variants of corrosion, reflecting both the impact of different environments and the failure mechanism.

Forging vs. Casting: Which is better?

Forging and casting are fundamentally different processes, so any comparison must consider the particular component and requirements.

What is trepanning?

Trepanning is the process of creating a hole through the centre of a solid bar, where the metal is removed as a smaller solid bar.

What is deep hole boring?

A deep hole is normally considered to be one where its depth is 10 x greater than its diameter.

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.

What is the difference between Alloy 825 and Alloy 925?

Alloy 825 and Alloy 925 are nearly identical in composition, but Alloy 925 is appreciably higher strength.
