Spacification
아이시 1045 steel is a medium tensile steel supplied in a black hot-rolled or normalized condition. It has a tensile strength of 570 – 700 MPa and Brinell hardness ranging between 170 그리고 210.
아이시 1045 steel is characterized by good weldability, good machinability, and high strength and impact properties in either the normalized or hot-rolled condition.
아이시 1045 steel has a low through-hardening capability with only sections of around 60 mm in size being recommended as suitable for tempering and through-hardening. 하지만, it can be efficiently flame- or induction-hardened in the normalized or hot rolled condition to obtain surface hardnesses in the range of Rc 54 – Rc 60 based on factors such as section size, type of set up, quenching medium used etc.
아이시 1045 steel lacks suitable alloying elements and hence does not respond to the nitriding process.

열처리
아이시 1045 is subjected to forging, annealing, normalizing, stress-relieving, hardening and tempering processes – each of which is explained in more detail below:
- 단조 – Heat to 850°C – 1250℃ (1562°F – 2282°F). Hold until the temperature is uniform. Cool in a furnace.
- 가열 냉각 – Heat to 800°C – 850℃ (1472°F – 1562°F). Hold until the temperature is uniform. Cool in a furnace.
- 정규화 – Heat to 870°C – 920℃ (1598°F-1688°F). Hold until the temperature is uniform. Soak for 10 – 15 minutes. Cool in still air.
- Stress-Relieving – Heat to 550°C – 660℃ (1022°F – 1220°F). Hold until the temperature is uniform. Soak for 1 hour per 25mm of section. Cool in still air.
- 경화 – Heat to 820°C – 850℃ (1508°F – 1562°F). Hold until the temperature is uniform. Soak for 10 – 15 minutes per 25mm of section. Quench in water or brine.
- 템퍼링 – Re-heat to 400°C – 650℃ (752°F – 1202°F) as required. Hold until the temperature is uniform. Soak for 1 hour per 25mm of section. Cool in still air.
