Categories, grades and product forms

In this section more information about the different categories, grades and product forms of stainless steels can be found.

Martensitic Stainless Steels

Martensitic stainless steels have an excellent strength to weight ratio, strong resistance to corrosion, a good hardness and a wide range of applications, of which the best known are probably knife steels, which are capable of holding a sharp edge.

To provide the right environment for further growth of this range of materials it was necessary to research existing and potential applications, to provide a technical introduction to the material and testimonials from existing producers who have used the material and can talk with authority about its value.

Duplex Stainless Steels

Duplex stainless steels form the latest family of stainless steels, tested as early as in the 1930’s and mass produced from the 1970’s onwards. Their excellent mechanical properties and their corrosion resistance have made them a first choice material for high-load applications in corrosive environments.

This reference document will inform and guide readers in how to appropriately select the correct duplex stainless steel for specific projects. It will also provide sound guidance for the selection of duplex stainless steels, when this family of stainless steels may not have been otherwise considered. This brochure is recommended for producers, material specifiers, architects, OEMs and stockists, with the knowledge that they will all find this a helpful tool in their material selection decisions and market development activities.

The Ferritic Solution

Ferritic stainless steels share most of the mechanical and corrosion-resistance properties of their more expensive cousins, austenitic stainless steels. However, unlike the austenitics, ferritic stainless steels contain no nickel. This makes them a cost-effective alternative in many applications.

The Ferritic Solution provides an overview of the properties of ferritic stainless steels, the advantages of using them and the applications where they can be used. The Ferritic Solution is a crucial reference document for stainless steel users, specifiers and producers.

This brochure is available in Chinese, English, French, German, Hindi, Italian, Japanese, Korean, Portuguese, Spanish and Turkish.

Practical Guidelines for the Fabrication of High Performance Austenitic Stainless Steels

In recent years, new highly corrosion-resistant austenitic stainless steels have entered the marketplace. They have demonstrated cost-effective performance in a variety of harsh and corrosive environments. This brochure provides basic information on HPASS grades and compares them to the standard grades. Its primary focus is to compare the fabrication characteristics of the two groups of steels, and to identify similarities and differences between them. This information will help those responsible for fabricating HPASS to manufacture a high-quality product that will perform successfully in the field.

Terminology

Navigating the complexities of terminology can be confusing if you don’t have a degree in metallurgy. How are stainless steels and CRAs categorized and graded? What is the difference between a superaustenitic, a superalloy and a nickel alloy? How do all the grading systems gear with one another? This article attempts to guide you through the labyrinth of stainless steel and CRA terminology.

Austenitic Chromium-Manganese Stainless Steels: A European Approach

For Cr-Mn stainless steel to become more acceptable in a European environment, a high level of standardisation is required. Providing technical information has been made a priority, to avoid misunderstanding and improper use.
To respond to these needs, a working group with representatives of the main European flat stainless steel producers was created, under the umbrella of Euro Inox. Its main conclusions are present in this publication.

200 series stainless steels - high manganese (CrMn)

Most growth in 200-series use over recent years has been in low-nickel and therefore lowchromium versions which have less corrosion resistance than grade 304. The end result has been corrosion failures in some applications and dissatisfied customers.
