    Classification of Stainless Steels Historically, stainless steels have been classi-fied by microstructure and are described as austenitic, martensitic, ferritic, or duplex (austenitic plus ferritic). In addition, a fifth family, the precipitation-hardenable (PH) stain-less steels, is based on the type of heat treat-. This article deals with the wrought stainless steels used for high temperature applications. It gives some typical compositions of wrought heat-resistant stainless steels, which are grouped into ferritic, martensitic, austenitic, and precipitation-hardening (PH) grades.

    1 General characteristics The Therma range contains 12 products for use in applications with high service temperatures (≥ °C/ °F). Ferritic stainless steels have resistance to sulfur containing hot gases and lower thermal expansion. Abstract. To gain knowledge about the applicability of ferritic stainless steels in exhaust pipes and other high temperature applications, mechanical testing of EN (ASTM S) and EN (ASTM ) was conducted at °C and °: Kauko Östman, Matti Isakov, Tuomo Nyyssönen, Veli-Tapani Kuokkala.

    The Cr/Ni austenitic steels are also very resistant to high temperature oxidation because of the protective surface film, but the usual grades have low strengths at elevated temperatures. Those steels stabilized with Ti and Nb, types and , can be heat treated to produce a fine dispersion of TiC or NbC which interacts with dislocations.   1.

Ferritic stainless steels are magnetic, non-heat-treatable steels that contain 11–30% chromium but little or no nickel. They are typically employed for nonstructural applications where there is a requirement for good general corrosion resistance or good stress corrosion resistance (an unfortunate synergy of stress and corrosion leading to.

Ferritic Stainless Steel Grades. Ferritic stainless steels are classified in the series, usually with 10% to 30% chromium content, and are often chosen for their excellent corrosion resistance and elevated temperature oxidation resistance.

Monograph 3 Ferritic Steels for High-Temperature Applications book a detailed review of the development of the high-chromium ferritic/martensitic steels for exposure to the high-energy neutron environment of a fission or fusion reactor.

Since the steels are used extensively for a range of high-temperature applications, this book also provides insight into the basic properties of the steels Cited by: 1.

(ii) Low activation ferritic/martensitic steels. Fe–Cr–Mo ferritic/martensitic steels have been used for heat exchangers and core structural materials for fast breeder reactors because of low void swelling rate and reasonable high-temperature strength. For fusion applications, one wt.% of molybdenum may be replaced by 2 wt.% tungsten.

The most commonly used ferritic steels are found in Group 2. They have a higher chromium content and are, consequently, more resistant to corrosion by nitric acids, sulfur gases, and many organic and food acids. In some applications, these grades can be used as a replacement for austenitic stainless steel grade   New generation general-purpose ferritic grade AWM GP™ can be used to replace the workhorse austenitic grade in most applications.

It is a corrosion resistant ferritic stainless steel with excellent strength, toughness, fabrication characteristics and weldability. The present investigation focuses on a new concept of high strength, high chromium ( wt.%), fully ferritic steels on the technical basis of Crofer® 22 H for the application in high Author: Jennifer Lopez Barrilao.

Background: Stainless steels are most commonly used for their corrosion resistance. The second most common reason stainless steels are used is for their high temperature properties; stainless steels can be found in applications where high temperature oxidation resistance is necessary, and in other applications where high temperature strength is required.
