Course Information

In this course, you will learn about stainless steel.  Stainless steel is a specialized type of steel which appears to be more complex than it really is.  

You will have access to the course for 90 days to work through the content.

There are over 100 different grades, each designed to address specific conditions. Understanding product properties, makeup and characteristics, provides an opportunity to make better informed decisions.

Many things have changed over the years including new grades, advanced processing practices, tighter tolerances and specifications, ISO Standards, production consistency, traceability, just to name a few.   

This course is designed to provide you with a high-level, simplified working knowledge of stainless steel; how and why it came to be; what the differences are between the grades and why; how product surface finishes are obtained; types of corrosion typically experienced; and what factors should be considered when selecting a grade.

Learners who successfully complete this course will earn a digital badge and certificate of course completion that can be shared on social media, downloaded as a PDF, and even embedded in an email signature.

Below is an overview of what you will learn in this course.
