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, 2018
Maraging 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.

Hydrogen trapping in high strength 0Cr16Ni5Mo martensitic stainless steel

Journal of Central South University, 2015
Hydrogen trapping behavior has been investigated by means of thermal desorption spectroscopy (TDS) for a high strength steel after it was tempered at the temperatures of 430 °C, 500 °C and 520 °C, respectively. The loss of ductility was characterized by slow strain rate test (SSRT) and microscopic observation.

Microstructure and Mechanical Properties of Martensitic High-Strength Engineering Steel

Metallurgist, 2020
A 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 ...

The application of dispersion strengthening of martensite in the design of high-strength steels

Materials Science and Engineering, 1975
Abstract With some plain carbon and alloy steels, structures consisting of a matrix of lath martensite strengthened by fine dispersed particles were obtained by unconventional methods of heat-treatment. It was proved that this type of structure is very effective in increasing both strength and ductility.

Martensitic Transformation in a Low-Alloy Ultra-High-Strength Steel

Advanced Materials Research, 2011
Martensitic 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.

Low-carbon high-strength alloy steels of the martensitic class

Metal Science and Heat Treatment, 1980
1. 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 ...

Microstructure control for high strength 9Cr ferritic–martensitic steels

Journal of Nuclear Materials, 2012
Abstract 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.

Thermal Desorption Analysis of Hydrogen in High Strength Martensitic Steels

Metallurgical and Materials Transactions A, 2011
Thermal 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.
