Type stainless steel s also advantageous for high temperature service because of its good mechanical properties. Type stainless steel offers higher creep and stress rupture properties than Type and, particularly, Type L which might also be considered for exposures where sensitization and intergranular corrosion are concerns. Stainless Steel - Grade Grade / L Technical Data Summary. Grade is an improved version of CS , with the addition of molybdenum and a slightly higher nickel content. The resultant composition of CS gives the steel much increased corrosion .

Introduction to Stainless Steels STAINLESS STEELS are iron-base alloys that contain a minimum of about 12% Cr, the amount needed to prevent the formation of rust in unpolluted atmospheres (hence the designa-tion stainless). Few stainless steels contain more than 30% Cr or less than 50% iron. They achieve their stainless characteristics through.   Precipitation hardening steels can be supplied in a readily machineable condition. After fabrication, a single, low temperature heat treatment can dramatically increase the strength of the steel. The properties, applications and fabrication details are provided for PH () stainless steel.

Philadelphia, American Society for Testing Materials []. Stainless steels are widely used at elevated temperatures when carbon and low-alloy steels do not provide adequate corrosion resistance and/or sufficient strength at these temperatures. This article deals with the wrought stainless steels used for high temperature applications.

Stainless steel have good strength and good resistance to corrosion and oxidation at elevated temperatures. Stainless steel are used at temperatures up to ° F for and and up to F for the high temperature stainless grade (S) and up to ° F for (S).

Stainless steel is used extensively in heat exchanger, super-heaters, boiler, feed water heaters, valves and main steam. increase, however, elevated-temperature properties quickly become the primary concern.

The family of stainless steels is most versatile in its ability to meet the requirements of high-temperature service. This booklet discusses factors that should be considered by engineers facing problems in designing equipment for high-temperature service.

"Report on the Elevated-Temperature Properties of Chromium. Stainless steels are mainly used for their re-sistance to aqueous corrosion but are also widely used at high temperatures when carbon and low-alloyed steels do not pro-vide adequate corrosion resistance and/or strength.

They can be found in applications in which high-temperature oxidation resist-ance or high-temperature strength are re-quired [1]. Stainless steels derive their inherent corrosion resistance from the presence of certain alloying elements, primarily chromium and nickel, which result in differences in microstructure compared to carbon steel.

The physical and mechanical properties of stainless steels at room temperature, and at elevated temperatures, also differ from carbon. basic stainless steels offer improved fabrication properties in turn, each modification is given a different name or tYpe number dependent upon its chemical analysis We can see, then, that the entire stainless steel family continues to grow because of variations to improve important fabrication qualities within the basic 11 alloy groups.

A DESIGNERS' HANDBOOK SERIES N o HIGH-TEMPERATURE CHARACTERISTICS OF STAINLESS STEELS. The magnetic properties of ten types of ferritic and martensitic stainless steels have been measured at room temperature and at 77K.

The steel samples studied were in the annealed state as. assessment of fire safety requires that the material response at elevated temperature can be predicted.

However, past work on structural design with stainless steel has been mainly focused on the austenitic and duplex grades [3, 4, 5].

The reduction of mechanical properties of ferritic stainless steels under fire conditions is largely unknown.

Reference is often made to stainless steel in the singular sense as if it were one material. Actually there are over 50 stainless steel alloys.

Three general classifications are used to identify stainless steels. They are: 1. Metallurgical Structure. The AISI numbering system: namely.

The principal metallurgical difference is that the high alloy content of the stainless grades causes the. tion Temperature (DBTT) is taken at the temperature at which the slope of the curve changes.

This is shown schemati-cally in Fig 5. Most steels suffer from a loss of tough-ness as the temperature drops to freezing point (0°C) and below. The actual Impact Strength at the DBTT varies for different steels.

In addition to excellent corrosion resistance and strength properties, the TypesL,and L Cr-Ni-Mo alloys also provide the excellent fabricability and formability which are typical of the austenitic stainless steels.

Two initial criteria (oxidation resistance and oxide scale electrical conductivity) were used to reduce the list.
