1. In steels with 0.25–0.35% C and 10–14% Ni the mechanical properties after quenching (cooling in air) are approximately the same as for carbon-free maraging steels: σb=190−200 kg/mm2; δ=10–12%; ψ=45–50%;an=6–7 kg-m/cm2;ap=1.7–2.2 kg-m/cm2. Small cold plastic deformation (2–5%) substantially increases the strength characteristics: ΔσT=50−60 kg/mm2,

Favourable Steel Structures using High Strength Steels
ce/papers, 2021AbstractAs a part of the European RFCS‐project STROBE, HOCHTIEF Engineering has developed a calculation programme as the basis of a web‐tool for the design and optimization of steel beams. The programme is suitable for steel girders of normal strength and for high strength girders up to S690 including welded hybrid girders. In this paper, the developed

High strength austenitic steels
Metal Science and Heat Treatment of Metals, 1959‘Transitional’ steels have an unusual combination of mechanical properties. They may have a low yield stress (20–40 kg/sq. mm=28, 400–56, 900 psi) and a high tensile strength (100–200 kg/sq mm=142, 000–284, 000 psi). The mechanical properties of these steels depend mainly on the extent to which austenite decomposes into martensite in deformation, and ...

High-Strength, Low-Alloy Steels
Science, 1980High-strength, low-alloy (HSLA) steels have nearly the same composition as plain carbon steels. However, they are up to twice as strong and their greater load-bearing capacity allows engineering use in lighter sections. Their high strength is derived from a combination of grain refinement; precipitation strengthening due to minor additions of vanadium,

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.

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.
