STEELMAX Steel Story

S355J2C, 1.0579 재질은 항복강도 355 MPa 로, 고장력강이면서
영하 20℃ 에서 CVN 충격 시험이 있는 환봉 규격입니다.

EN 10277-2 규격의 S355J2C 강재에 As Rolled + Turned 인 경우는
Symbol +SH 로 표기하고, Cold Drawn +C 로 표기해 구분합니다.

S355J2C +C, S355J2C +SH 모두 Bright Bar EN 10277-2 규정 강재로
냉간 인발 또는 냉간 압연과 Turned (Lathe turning : 旋削 : 선삭) 냉간재입니다.

S355J2 +SH 인 경우는 Diameter 16 mm 이상
S355J2 +C 인 경우는 Diameter 5 mm 부터 기계적 성질이 있습니다.

※ Turned products (Lathe turning : 旋削 : 선삭 제품) : Symbol +SH (DIN-EN)
Round bars products by turning on a lathe where the products
can be further processed by straightening and polishing.
This operation gives the bar special features with respect to shape,
dimensional accuracy and surface finish.
The removal of metal is carried out in such a way that the bright
product is generally free from rolling defects and surface decarburization.
For technical reasons some bars ordered as hot rolled products may be
delivered roughly turned(peeled), nevertheless such products are
treated as hot rolled products and not as bright products.

※ Cold finished steel bars (마봉강 : 摩棒鋼, Bright Bar)
Finishing steel bar with cold drawing, grinding, cutting,
smooth turned, rough turned, centerless, cold rolling
or combination of them to improve the surface
quality and dimension precision
The term “Cold Finish” is an umbrella definition for any
material that has had some sort of surface treatment
There are round, square, hexagon, flat and so on according
to the cross-sectional shape.

강재를 냉간 인발, 연삭, 절삭, 센터리스 또는 이들의 조합으로
마무리한 봉강으로, 봉강 뿐 아니라, 원형, 정방형,
육각형, 장방형 및 이형 등이 있습니다.
