A786 Floor Plate, Raised Thread Pattern

A786 Floor Plate, Raised Thread Pattern
STEELMAX Steel Story

A786 규정에는 열간압연 탄소강, 저합금강, 고장력 저합금강,
그리고 합금강 Floor Plate (체크 플레이트) 제품에 대한 규정으로

마루, 계단, 운송장비, walkways, running board, truck bed flooring,
entrances, tranch covers 등, 미끄럼 방지용 (skid resistance)으로 쓰입니다.

A786 규정 중 탄소강 Floor Plate, Raised Thread Pattern 제품 원소재는
ASTM A1018 Grade 33 commercial grade — 항복강도 230 MPa minimum 을

사용하며, 인장강도 360 MPa minimum 으로, ASTM A36 강재보다는
기계적 성질에서 약간 아래인 grade 강재로 raised thread pattern 제조합니다.

※ Mechanical properties (기계적성질 : 機械的性質)
Various properties relating to mechanical deformation and
breaking such as tensile strength, yield point or proof strength,
elongation, reduction of area, hardness, impact value,
fatigue strength, creep strength, etc.

인장강도, 항복점, 연신율, 단면수축율, 경도, 충격치, 피로강도,
크리프 강도 등 기계적인 변형 및 파괴에 관계되는 성질을 말합니다.

※ 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% Carbon
Medium-carbon steels (중탄소강), which contain 0.30% to 0.60% Carbon
High-carbon steels (고탄소강), which contain 0.60% to 1.00% Carbon
