STEELMAX Steel Story

MIl-A-46100 재질은 장갑 강판에 대한 규정으로
총알로부터 보호되어야 할 장비의, 경량화 합금 강판 규정입니다.

MIL-A-46100 재질은, Hardness (경도), Formability (성형성),
Weldability (용접성), Toughness (인성), Flatness (편평성) 을,

고루 갖춘 우수한 방탄 장갑용 강판 규정이고, 이 강재의 방탄 성능은
EN 1522 규정에 따르기도 하고, 제조사 자체 규정을 따르기도 합니다.

EN 1522 규정은 권총, 라이플, 총으로부터 발사된 총알에 대한
windows, doors, shutters and blinds 저항성에 대한 규정입니다.

EN 1522 Standard specifies the requirements and classification
that windows, doors, shutters and blinds — Bullets resistance .

MIL-A-46100 재질은 nominal BHN 500 수준의 경도이며
4.7mm (3/16″) ~ 50.8mm (2″) 수준의 두께입니다.

충격 저항성 (CVN : Charpy V-Notch Impact Test) 에서
Longitudinal -40℃/34 joule, Transverse -40℃/27 joule 입니다.

MIL-A-46100 재질은 combat vehicles, armored carriers, tanks,
ballistic protections for building, military vehicles 용도로 사용됩니다.

※ Longitudinal directions (압연 방향 : 壓延方向)
The principal direction of flow in a worked steel.
Usually the length of the plate.
Grain direction also runs the length of the plate.

※ Transverse directions (역방향 : 逆方向)
Literally, across usually signifying a direction or plane
perpendicular to the direction of working.

※ Charpy V-Notch Impact Test (CVN : 샤르피 충격 시험)
Test to measure the absorbed energy, impact value, percentage
of brittle/ductile fracture, transition temperature, etc. with using
charpy impact testing machine in which test piece is supported by
two supports distant by 40mm so that the notch meets the middle
between supports and is broken by striking with one blow of
pendulum to the face opposite the notch.

샤르피 충격 시험기를 사용하여 시험편을 40mm 간격이 있는 두 개의
지지대에 올려 놓고, 또는 노치부를 지지대 사이의 중앙에 놓고
노치부의 뒷면을 해머로 1회만 충격을 주어, 시험편을 파단 시키고
흡수 에너지, 충격치, 파면율, 천이 온도 등을 측정하는 시험.
