Advanced High Strength Martensitic Stainless Steels for High Pressure Equipment
Volume 5: High-Pressure Technology; ASME Nondestructive Evaluation, Diagnosis and Prognosis Division (NDPD); Rudy Scavuzzo Student Paper Symposium and 26th Annual Student Paper Competition, 2018Maraging stainless steels offer a large panel of high strength materials with good ductility and stress corrosion cracking resistance. Their mechanical properties compared to conventional 15-5 PH and 17-4 PH martensitic stainless steels show much better yield strength / toughness compromise for yield strength exceeding 1300 MPa.

Microstructure control for high strength 9Cr ferritic–martensitic steels
Journal of Nuclear Materials, 2012Abstract Ferritic–martensitic (F–M) steels with 9 wt.%Cr are important structural materials for use in advanced nuclear reactors. Alloying composition adjustment, guided by computational thermodynamics, and thermomechanical treatment (TMT) were employed to develop high strength 9Cr F–M steels.

High Strength High Carbon Low Alloy Pearlite-Ferrite-Tempered Martensite Steels
Transactions of the Indian Institute of Metals, 2014High strength multiphase steels have been developed consisting of combination of pearlite, tempered martensite and small amount of ferrite, by suitable heat treatment of a high carbon low alloy rail steel (0.7 % C). The desired microstructure has been obtained by holding fully homogenized steel in pearlitic range for small durations followed by water ...

Microstructure and Mechanical Properties of Martensitic High-Strength Engineering Steel
Metallurgist, 2020A promising martensitic steel with good hardenability is studied. In the cooling rate range 0.1–30°C/sec and the only transformation recorded by a dilatometer starts at an Ms temperature of 355 ± 10°C. Microstructure and mechanical properties of the steel studied are analyzed after various heat treatment regimes: cooling from the austenitizing ...

Low-carbon high-strength alloy steels of the martensitic class
Metal Science and Heat Treatment, 19801. We investigated new high-strength low-carbon steel of the 15Kh3G3MF type with a good combination of mechanical properties: σb = (14-13)· 108 Pa; σ0.2 = (10.7-9.8) · 108 Pa; ψ=60–57.5%; δ=14–12%;a1 = 11.3-8.7 daJ/cm2) 2. The optimal heat treatment for this steel is oil quenching from 920±10°+tempering at 200° with cooling in water or ...

Vibration Stress Relief Treatment of welded high-strength martensitic steel
Welding in the World, 2011The influence of a vibration stress relief (VSR) treatment on the residual stresses for welded specimens of ultra high-strength steel (ARMOX 500T®) was investigated. For the residual stress measurements X-ray diffraction and magnetic Barkhausen noise analysis (BNA) were utilized.

Hydrogen Trapping in Some Automotive Martensitic Advanced High‐Strength Steels
Advanced Engineering Materials, 2017Hydrogen permeation experiments are used to investigate hydrogen trapping in commercial automotive martensitic advanced high‐strength steels. Hydrogen trapping increases with increasing mechanical strength, as indicated by (i) the decrease in the hydrogen diffusion coefficient, and (ii) the increase in reversible hydrogen trap density.

Hydrogen Embrittlement Testing of High Strength Low Carbon Martensitic Steels
CORROSION 2010, 2010Abstract High strength carbon steels are being used as the external reinforcement for a novel composite pipeline. This system combines a thin wall corrosion resistant alloy with the reinforcement to produce a high pressure pipeline which is manufactured on site giving a lower cost alternative to conventional thick-wall pipelines. Despite
