04. Martensitic Stainless Steels

Martensite, the hardest structural component in steels, is responsible for the high hardness in many sharp edge tools. The formation of martensite is a remarkable phenomenon in materials science and smiths have known for at least 3000 years how to make use of it to produce implements such as

04. Molybdenum and tungsten in duplex steels

In my previous column, I promised to give an overview of the role of molybdenum and tungsten in duplex stainless steels (DSS). They are neighbors of chromium in the periodic table (Group 6B) and even more potent than chromium in preventing pitting, which is shown in the familiar PRE-relation:
