Steels with controlled hardenability for induction hardening
Metal Science and Heat Treatment, 1980Steels of the CH and LH type developed in the Soviet Union permit the use of a new method of induction hardening — bulk-surface hardening — and efficient utilization of the high-strength conditions (σb = 230–250 kgf/mm2). These steels make it possible to improve the structural strength, operating characteristics, service life, and reliability of ...

Steel hardenability and failure analysis
Practical Failure Analysis, 2001Abstract Hardenability evaluation is typically applied to heat treatment process control, but can also augment standard metallurgical failure analysis techniques for steel components. A comprehensive understanding of steel hardenability is an essential complement to the skills of the metallurgical failure analyst.

Abstract This chapter addresses the concept of hardenability by first describing the basic hardening process for steel, starting with austenitization followed by quenching and tempering. The context also serves to clarify the difference between hardenability and hardness, which are often confused.

Metal Science and Heat Treatment, 1966
1. Preliminary high-temperature tempering of 65S2VA steel reduces the hardness after quenching from the ordinary quenching temperature of 860°C. 2. The original hardness of the quenched steel can be reestablished only by heating to 1000°C or higher.

Hardness and Hardenability of Steels
2020Abstract The hardenability of steel is governed almost entirely by the chemical composition (carbon and alloy content) at the austenitizing temperature and the austenite grain size at the moment of quenching. This article introduces the methods to evaluate hardenability and the factors that influence steel hardenability and selection ...

Hardness and Hardenability of Steels
2013Abstract Hardenability refers to the ability of steel to obtain satisfactory hardening to some desired depth when cooled under prescribed conditions. It is governed almost entirely by the chemical composition (carbon and alloy content) at the austenitizing temperature and the austenite grain size at the moment of quenching.
