Mar 18, 2020 · The material used is a high strength steel plate with a thickness of 16 mm and employed in the manufacture of line pipes produced in a commercial heavy plate mill. The chemical composition is shown in Table 1. The plate was made through TMCP and accelerated cooling process in the mill. Effects of microstructure on crack resistance and low May 01, 2019 · Assessing and predicting impact toughness of high strength steel has always been an active field of research (Lee et al., 2015; Zhao et al., 2017). The methods to maintain the high yield strength while increase low-temperature toughness is constantly pursued through either composition design or processing routes for advanced high strength steels.
In this paper, three different kinds of steel fibers, being micro (M), end-hooked (H), and corrugated (C), commonly used in engineering applications, are added to high-strength lightweight aggregate concrete (HLAC) to study the effects of steel fiber and volume content ratio of fiber on the compressive, splitting tensile, and flexural strength of HLAC. The range of steel fiber volume content General Catalog of TOOL STEELS - Hitachi Metalstoughness for general use.

High hardness is achieved by annealing steels with relatively high carbon content in the heat-treating furnace and then quickly water-cooling them in the quencher. This is the conventional technology. The high carbon content makes steel hard, but also brittle, and high degrees of toughness High-Strength Low-Alloy Steels - ASM Internationalenhance strength, toughness, formability, and weldability Acicular ferrite (low-carbon bainite) steels,which are low-carbon (less than 0.05% C) steels with an excellent combination of high yield strengths, (as high as 690 MPa, or 100 ksi) weldability, formability, and good toughness Dual-phase steels,which have a microstructure of martensite dis-
