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 increases, because the fraction of ferrite is reduced during solidification. Nitrogen is dissolved more readily during austenitisation than carbon which lowers the C/N ratio at hardening… 

Nitrogen and Ausforming to Improve Stainless Martensitic Steels

The chromium content of standard martensitic stainless steel X65Cr14 is raised to 17 mass% to enhance the solubility of nitrogen. Up to 4 mass% of nickel are added to suppress a partially ferritic

New Developments in Martensitic Stainless Steels Containing C + N

The use of nitrogen in martensitic stainless steels is limited by its solubility. Nitrogen solubility can be increased by alloying with elements such as Cr, Mn, and Mo and the use of pressure, such

Corrosion properties of a complex multi‐phase martensitic stainless steel depending on the tempering temperature

In this work, the corrosion resistance of X190CrVMo20‐4‐1 martensitic stainless steel and the hardness are correlated with the tempering temperature. The steel was hardened from a typical

Modeling Hardenable Stainless Steels Using Calculated Martensite Start Temperatures in Thermodynamic Equilibrium Calculations

In this work, martensite start temperatures of several martensitic stainless steels containing different amounts and types of carbides were calculated by means of thermodynamic equilibrium

Hardness and Microstructure of a Newly Developed Stainless Steel after Ausforming

In this work, ausforming is applied to a newly developed stainless steel. This process consists of austenitisation, quenching to a deformation temperature above room temperature, deformation of the

Development of a powder metallurgical corrosion-resistant bearing steel containing NbC and its transfer to industrial applications

In this work, a new powder metallurgical corrosion-resistant bearing steel containing NbC was developed based on thermodynamical equilibrium calculations using CALPHAD (CALculation of Phase Diagrams)


Niobium, like titanium and vanadium, forms super-hard mono-carbides (MC) which remain relatively pure in Fe-base alloys on account of their low solubility for other metallic alloying elements.

Konzept zur Verbesserung der Meerwasserbeständigkeit von Wälzlagerstahl

Zur Entwicklung von korrosionsbeständigen härtbaren Wälzlagerstählen für die Meerwassertechnik wurden die Gehalte an Mo und Cr gegenüber X65Cr14 erhöht und der C‐Gehalt durch Nutzung des löslichen



Carbon or nitrogen alloyed quenched and tempered stainless steels : a comparative study

Some conventional stainless quenched and tempered steel grades were modified by substituting nitrogen for carbon and by variing the contents of chromium, molybdenum and nickel. Results of a

Intensive Interstitial Strengthening of Stainless Steels

The high chromium content of stainless steel impairs the interstitial solubility of carbon in austenite at solution annealing or hardening temperature. Replacing carbon by nitrogen improves the

Tempering of Martensitic Stainless Steel with 0.6 w/o Nitogen and /or Carbon

Martensitic stainless high nitrogen steels are used for advanced bearings because of their superior corrosion resistance and hot hardness. Therefore the tempering behaviour of steels SC, SN and SNC

Precipitates in Tempered Stainless Martensitic Steels Alloyed with Nitrogen, Carbon or Both

The precipitation in martensitic steels alloyed with (wt. %) ∼15Cr, ∼IMo, 0.62N or 0.6 %C or 0.29C+0.35N is studied after tempering in the range of 100-650°C by means of transmission electron

Nitrogen Bearing Martensitic Stainless Steels : Microstructure and Properties

Three experimental nitrogen bearing martensitic stainless steels (nitrogen content ranging from 1600 to 1900 ppm) were produced in an air induction furnace and the N was added into the melt as

Diffusion alloying – a new manufacturing method for PM tool steels

Abstract To increase the wear resistance of tool steels, high contents of super-hard MC type carbides formed by Ti, V or Nb are desirable. Unfortunately, these carbides precipitate primarily from the
