STEELMAX Steel Story

Standard European Profiles A-Rail 은, A100 을 포함해
Profile A45-A150 까지, 7가지 Profile가 있습니다.

A100 Crane Rail, 강도는 700 or 70 Type로,
탄소량 Nominal 0.50%이며, 인장강도 min 690 N/㎟ 과

900 or 90 Type로, 탄소량 Nominal 0.70%,
인장강도 min 880 N/㎟ 두 가지 Type이 주로 사용됩니다.

※ Tensile Strength (인장강도 : 引張强度)
Value of maximum load during tensile test divided by the
original sectional area of parallel portion.
As for materials in which the maximum load withstood by test piece
after yielding is lower than the upper yield point, it shall be the
value of the maximum load after yielding divided by original
sectional area of parallel portion.
인장시험에서 시험편의 평행부가 두 동강 날 때까지 견딘 최대 하중.
