※ 연화 (Softening, Soft annealing)
철강재의 경도를 원하는 수준까지 낮추기 위해 시행하는 열처리를 말합니다.

Heat treatment in which heating is carried out around temperatures of Ac1
transformation point with the object of reducing the hardness of the
ferrous product to a given level.

※ Mechanical properties (기계적 성질 : 機械的性質)
Various properties relating to mechanical deformation and
breaking such as tensile strength, yield point or proof strength,
elongation, reduction of area, hardness, impact value,
fatigue strength, creep strength, etc.

인장강도, 항복점, 연신율, 단면 수축율, 경도, 충격치, 피로 강도,
크리프 강도 등 기계적인 변형 및 파괴에 관계되는 성질을 말합니다.

※ Spring steels (스프링강) — EN 10089
Materials which are, because of their properties in the quenched and tempered
condition, particularly suitable for the manufacture of spring like components
of all kinds. The resilience of the steels depends on their elastic deformability,
which enables them to sustain loading within a given range without exhibiting
any permanent deformation when the load is removed.
The properties required of the steels for springs are obtained by higher carbon
contents and alloying constituents such as silicon, manganese, chromium,
molybdenum and vanadium, and also by heat-treatment, i.e hardening with
subsequent tempering.
