Specifications define a couple hundred stainless steel grades, differing from one another mainly in chemical composition. Composition is a fundamental characteristic of stainless steel because it determines the alloy’s corrosion resistance, microstructural phase balance, mechanical properties, and physical properties. The … Continue reading →

Duplex stainless steels are called “duplex” because they have a two-phase microstructure consisting of grains of ferritic and austenitic stainless steel. The picture shows the yellow austenitic phase as “islands” surrounded by the blue ferritic phase. When duplex stainless steel … Continue reading →

One of the features that characterize stainless steels is a minimum 10.5% chromium content as the principal alloying element. Four major categories of wrought stainless steel, based on metallurgical structure, are austenitic, ferritic, martensitic, and precipitation hardening. Cast stainless-steel grades … Continue reading →

During a project on the development of sensors for the powder metallurgy industry, NIST has developed a technique for production of nitrogenated stainless steel alloys with enhanced corrosion and mechanical properties. Discussions with metal powder producers are underway to develop … Continue reading →

A nickel based alloy is an alloy whose main constituent is nickel. Nickel and nickel based alloys are vitally important to industry because of their ability to withstand a variety of severe operating conditions involving corrosive environment, high temperatures, high … Continue reading →
