Martensitic Transformation in a Low-Alloy Ultra-High-Strength Steel
Advanced Materials Research, 2011Martensitic transformation is the most important phase transformation strengthening the 30CrNi3MoV ultra-high-strength steel during heat treatment process. Characteristics of the martensitic transformation in the 30CrNi3MoV steel were investigated by means of dilatometric measurements and microstructural observations.

Vanadium Microalloyed High Strength Martensitic Steel Sheet for Hot-Dip Coating
2015Cold rolled steels with various vanadium and nitrogen levels have been treated to simulate the application of galvanizing and galvannealing to hardened martensitic microstructures. Strength levels were raised 100–150MPa by alloying with vanadium, which mitigates the effect of tempering.

Thermal Desorption Analysis of Hydrogen in High Strength Martensitic Steels
Metallurgical and Materials Transactions A, 2011Thermal desorption analyses (TDA) were conducted in high strength martensitic steels containing carbon from 0.33 to 1.0 mass pct, which were charged with hydrogen at 1223 K (950 °C) under hydrogen of one atmospheric pressure and quenched to room temperature.

Design of a low-alloy high-strength and high-toughness martensitic steel
International Journal of Minerals, Metallurgy, and Materials, 2013To develop a high strength low alloy (HSLA) steel with high strength and high toughness, a series of martensitic steels were studied through alloying with various elements and thermodynamic simulation. The microstructure and mechanical properties of the designed steel were investigated by optical microscopy, scanning electron microscopy, tensile ...

Microstructure and high-temperature strength of high Cr ODS tempered martensitic steels
Journal of Nuclear Materials, 2013Abstract 11-12Cr oxide dispersion strengthened (ODS) tempered martensitic steels underwent manufacturing tests and their ferritic–martensitic duplex structures were quantitatively evaluated by three methods: high-temperature X-ray diffraction (XRD), electron probe microanalyzer (EPMA), and metallography.

Performance of High Strength Super 13%Cr Martensitic Stainless Steels
CORROSION 2003, 2003Abstract Martensitic stainless steels have been widely used for oil country tubular goods because of their high strength and excellent corrosion resistance in CO2 gas wells. Recently, much attention has been paid for application of these steels in light sour environments even high strength.

A review of hydrogen embrittlement of martensitic advanced high-strength steels
Corrosion Reviews, 2016Abstract The martensitic advanced high-strength steels (MS-AHSS) are used to create fuel-efficient, crashworthy cars. Hydrogen embrittlement (HE) is an issue with high-strength steels; thus, the interaction of hydrogen with MS-AHSS needs to be studied. There are only a few published works on the HE of MS-AHSS.

Hydrogen Environment Assisted Cracking of Modern Ultra-High Strength Martensitic Steels
Metallurgical and Materials Transactions A, 2017Martensitic steels (Aermet®100, Ferrium®M54™, Ferrium®S53®, and experimental CrNiMoWV at ultra-high yield strength of 1550 to 1725 MPa) similarly resist hydrogen environment assisted cracking (HEAC) in aqueous NaCl. Cracking is transgranular, ascribed to increased steel purity and rare earth addition compared to intergranular HEAC in highly susceptible

Performance of High Strength Low C - 13%Cr Martensitic Stainless Steel
CORROSION 2007, 2007Abstract Low C - 13%Cr martensitic stainless steels have been widely used in the oil and gas industries because of their high strength and excellent corrosion res istance in corrosive conditions. Recently, higher strength(over 110 ksi grade) corrosion resistant alloys have been requested from users.

High Strength Modified Martensitic Stainless Steel Production Tubing for Sour Wells
CORROSION 2009, 2009Abstract This paper describes the material selection and the relative testing for production tubing in two fields, one onshore and the other offshore. Both fields are characterized by sour conditions with relatively low concentrations of H2S.
