High-strength nonmagnetic steel
Metal Science and Heat Treatment, 19631. 25Cr17Ni4G15AF2 steel has a high yield point (σ0.2>80 kg/mm2) and satisfactory plasticity (αk = 4 kgm/cm2) after quenching from 1180°C and aging 10 h at 700°C. 2. Vanadium strengthens this steel because it favors the precipitation of carbonitrides and the formation of the σ-phase, and also because of the small-grain structure produced.

<div class="htmlview paragraph">The development of new high-strength steels is an important topic at ThyssenKrupp Steel. Application of these new steel grades in automotive production can support significant weight reduction in order to achieve future CO<sup>2</sup> targets. However, it is necessary to consider certain requirements of

This chapter is concerned with the advanced high-strength steels (AHSS). The focus is on AHSS of second generation—the high-alloy austenitic steels with twinning-induced plasticity (TWIP) and transformation-induced plasticity (TRIP). For both groups, the state-of-the-art knowledge regarding the thermodynamic aspects, the deformation behaviour and the ...

1. Weldable high-strength steels can be divided into two groups: those with a ferrito-pearlitic structure and those consisting of acicular upper troostite. Steels of the first group are used either as-rolled or normalized. Their tensile strength is 55–71 kg/sq. mm; their weldability and impact toughness are good.

Fatigue strength of high-strength structural steels
Strength of Materials, 19821. The fatigue strength of high-strength steels 30KhN2MFA and 35KhN2MFA-Sh after quenching and tempering was studied in symmetrical cyclic bending with and without a stress raiser. 2. The fatigue strength of the steels was evaluated according to the appearance of a crack of standard size and in accordance with fatigue fracture ...

Metallurgical Design of High Strength/High Toughness Steels
Materials Science Forum, 2012The proper balance between yield strength, YS, and ductile to brittle transition temperature, DBTT, has been the main concern during development of high strength engineering steels and the effect of microstructure on impact toughness has attracted a great attention during the last decades.

Dynamic Strength Estimates for a High Strength, Experimental Steel
Volume 4: Fluid Structure Interaction, 2005For several years, the Air Force has been engaged in the development of high velocity air to surface missiles. The objective is to replace larger, high mass weapons with smaller, more versatile projectiles that can achieve the same goals. The reduction of mass requires that the impact velocity be increased to meet the performance requirements. This has

Structural strength of high-strength steel Kh5MSFA
Metal Science and Heat Treatment, 19911. The operating capacity of high-strength steel 38Kh5MSFA in structures with the same ultimate breaking strength depends markedly on the structural state. A high and stable structural strength (σbre/σf ≥ 1.0) with ductile breaking of model vessels is achieved after quenching and tempering at 300°C.
