A75, Crane Rail, DIN 536-1, 880 MPa Tensile Strength
STEELMAX Steel Story

A75 Crane Rail 은, 공장의 overhead gantry crane (갠트리 크레인),
floor-mounted crane, 창고, 항만, 부두에서 사용하는 크레인용 레일입니다.

※ A75 Crane Rail Dimension

Rail 높이 : 85mm, Rail 바닥 넓이 : 200mm, Rail 머리 넓이 : 75mm,
Rail 목 두께 : 45mm, Section : 71.6㎠, 단위중량 : 56.20 m/kg.

A75 Crane Rail 은, 인장강도에 따라 2가지 종류가 많이 사용되고
Tensile Strength 690 MPa, 880 MPa, 선택 사용됩니다.

A75 Crane Rail 은, 탄소강재로 탄소량으로 강도를 조정한 강재로
탄소량이 일반강재보다 비교적 높은 수준의 함량입니다.

※ Tensile Strength (인장강도) — DIN EN
Measures the engineering stress applied at the point when it fails.
The maximum amount tensile stress is called “Tensile strength”
It is determined by the tensile test.
Years ago a lot of construction steels were named according to
their tensile strength.
For example St37 (tensile strength is 370 N/㎟) or St52 (tensile
strength 520 N/㎟).
Nowadays they changed their designation and method has been
changed and yield strength is used.
For example S355JR (yield strength is 355 N/㎟) or S420 (yield
strength 420 N/㎟).

※ Carbon Steel (탄소강 : 炭素鋼) – AISI Definition)
Generally speaking carbon steels contain up to 2% total alloying
elements, and can be subdivided into as following categories
Low-carbon steels (저탄소강), which contain up to 0.30% C
Medium-carbon steels (중탄소강), which contain 0.30% to 0.60% C
High-carbon steels (고탄소강), which contain 0.60% to 1.00% C
