Martensitic Stainless Steels

2008
Abstract This chapter discusses the metallurgy, phase structure, thermal processing, and applications of martensitic stainless steels. The phenomenon of martensite formation is explained. A table listing the compositions of martensitic stainless steels is also presented.

Study on nitrogen in martensitic stainless steels

HTM Journal of Heat Treatment and Materials, 2011
Abstract Pressure metallurgy is a means of increasing the nitrogen content and thereby the resistance of stainless martensitic steels to pitting corrosion. The present study on their constitution and heat treatment reveals that even at normal pressure more nitrogen is dissolved in the melt if the carbon content ...

Tensile Properties of Martensitic Stainless Steel Weldments

Advanced Materials Research, 2007
In this study, AISI 420 martensitic stainless steels were welded by GTAW (gas tungsten arc welding) using ER 316L consumables. Pure argon, argon + 25% He and argon + 5% N2 were used as shielding gases. The obtained results indicated that shielding gases have some effect on the properties of the martensitic stainless steel weldments.

Development of low-activation martensitic stainless steels

Journal of Nuclear Materials, 1986
Abstract An evaluation has been made of the properties obtainable from elementally-substituted martensitic stainless steels, the objective being to achieve properties comparable with those of an established 12% CrMoVNb steel in a composition that would allow hands-on recycling after 100 y storage. Tungsten and increased contents of vanadium have been

New Martensitic Age Hardening Stainless Steels

1965
The development of three new martensitic stainless steels is described. As annealed these alloys possess a relatively soft martensitic structure which is amenable to cold processing and forming operations. Two of these alloys may be strengthened from 150,000 to 200,000 psi ultimate tensile strength by means of low temperature precipitation-hardening ...

Reversed austenite in 0Cr13Ni4Mo martensitic stainless steels

Materials Chemistry and Physics, 2014
Abstract The austenite reversion process and the distribution of carbon and other alloying elements during tempering in 0Cr13Ni4Mo martensitic stainless steel have been investigated by in-situ high temperature X-ray diffraction (XRD) and scanning transmission electron microscopy (STEM).

Heat Treating of Martensitic Stainless Steels

2014
Abstract Martensitic stainless steels are the least corrosion-resistant of all stainless alloys. The traditional martensitic stainless steels are iron/chromium/carbon alloys, sometimes with a small amount of nickel and/or molybdenum. This article provides an overview on the influences of the various possible alloying elements on the key ...

Austenite–Martensite Interface Dislocations in Stainless Steel

Nature, 1966
WHEN 18 chromium : 8 nickel austenitic stainless steel is plastically deformed at room and sub-zero temperatures, e (hexagonal closest packing) and α′ (body centred cubic) martensites are formed. The e phase forms as the result of the propagation of Shockley partial dislocations on every second {111} γ plane and appears in the form of thin disks having

The martensite transformation in stainless steel

The Philosophical Magazine: A Journal of Theoretical Experimental and Applied Physics, 1962
Abstract The nucleation of the low temperature h.c.p. ∊ and b.c.c. α phases produced by deformation in a 304 stainless steel has been studied by transmission electron microscopy. The ∊ phase has been found to be an intermediate phase in the nucleation of α martensite from the austenitic matrix.
