※ Stress Relieving(old name : stress relief annealing : 응력 제거 어닐링 (풀림)
Every piece of steel has an amount of internal stress caused
by steel production, machining, surface finish, heat treatment
and other processes.
During a heat treatment process the yield strength is reduced
to a lower level. If precision parts or complicated tools with
close tolerances, this deformation could cause problems.
In the case after rough machining and stress relieving is done
with a high degree of machining allowance.
After this process the internal stress is reduced by the parts deforming.
The standard process is slow heating up to 550~650℃, holding for
minimum 2 hours and finishing with a slow cooling in the furnace.

모든 철강재는 생산, 가공, 표면 마무리, 열처리와 기타 공정 진행에서
내부 응력이 어느 정도 쌓일 수 밖에 없고, 이런 내부 응력을 해소 시키려고
적당한 온도로 가열하고 균열화한 후, 적절한 온도로 냉각함으로써
실질적인 조직의 변화 없이 내부 응력을 줄이고자 시행하는 열처리를 말합니다.

※ Drawing (인발 : 引拔)
The process of pulling material through a die to reduce the size,
change the cross sectional shape, or to harden the material.

소재를 잡아 당겨, 다이를 통과시키면서 단면적이나 크기를
줄여 나가거나, 금속을 경화 시키기도 하는 방법

※ Aircraft Quality Steel (AQ Steel : 항공기강 : 航空機鋼)
AQ Steel is the most commonly specified quality for general aerospace applications.
It is defined in SAE specification AMS 2301, which outlines the procedure for determining
compliance with cleanliness requirements by the magnetic particle inspection method.
