Join Penn Stainless Products and Dr. Metals for our free technical seminar on Stainless Steel products, technology and maintenance. Stainless steel surfaces should be clean, smooth, and free from heavy surface oxides and contamination to provide optimum performance. During fabrication, the surface can alter and degrade corrosion resistance properties. Fabrication can contaminate the surface with free iron and other deposits, damage the passive film through chromium depletion, and damage the surface mechanically. After fabrication, it is essential to restore the properties by appropriate techniques.

Participants will learn simple techniques to reduce the risk of corrosion during the fabrication process:

  • Get the best out of Stainless Steel – How to maintain, protect and properly clean stainless steels
  • The science behind stainless — why Stain Less?
  • The impact of corrosion on society — understanding the inevitable
  • Bring on the heat — stainless steels in high temperature applications

The morning will be broken down into three segments.  Agenda details to follow.  

Get the best out of stainless steel

Stainless steel surfaces should be clean, smooth, and free from heavy surface oxides and contamination to provide optimum performance. During fabrication the surface can alter and degrade corrosion resistance properties. Fabrication can contaminate the surface with free iron and other deposits; it can damage the passive film through chromium depletion; and damage the surface mechanically. After fabrication it is essential to restore the properties by appropriate techniques. These techniques will be discussed during the seminar.

The science behind stainless

Stainless steels are iron-based alloys containing at least 10.5% Chromium, which are used primarily for their corrosion resistance. At this chromium level, a chromium-enriched surface oxide, called the passive layer or passive film, forms on the steel. There are many different stainless steels, but they all meet this minimum chromium requirement. The main types of stainless steels are: austenitic, ferritic, duplex, and martensitic. The main characteristics of the various alloy groups will be discussed.

The impact of corrosion on society

According to a recent study sponsored by the Federal Highway Administration (FHWA), corrosion costs the U.S. industry 3% of the gross national product (GNP) value. This means the direct costs, replacement and cost of corrosion protection is about $276 billion annually. In more comprehensible numbers, the cost is over $1000 per person each year. It is estimated that at least a third of the cost is unnecessary. Some of the main forms of corrosion that cause degradation of stainless steel will be discussed.

Bring on the heat

At elevated temperatures, properties of interest to the designer include mechanical ones, such as yield and tensile strength, creep strength or creep rupture, ductility, thermal fatigue, and thermal shock resistance. Properties that show environmental resistance include oxidation, carburization, sulfidation, and nitriding. A discussion on the various high temperature properties will be presented.

“Dr. Metals”, Hira Ahluwalia, Ph.D., is a scientist, metallurgist, materials and corrosion consultant to some of the world’s largest industrial consortiums, and president of Material Selection Resources, Inc. Dr. Metals has served as chairman of the National Association of Corrosion Engineers and is a recipient of that organization’s Distinguished Service Award. He has published over 20 articles.
