F 조건: RHEINFELDEN in-house performance ranges for Sand casting; test pieces were separately cast or taken from castings (PDF p. 75). The ranges have no reported wall thickness. Parenthetical values are separate casting minima for wall ≤20 mm; the sand-cast O yield minimum conflicts between PDF pp. 34 and 78.

화학 조성

검토를 마친 질량 백분율(wt%) 한계만 표시합니다. 비어 있는 한계는 다른 쪽 한계만 보고되었다는 뜻입니다.

The 2016 handbook reports composition in percent of mass. Single element values are upper maxima (PDF p. 76). The numerical designation 44 000 applies only if Si is below 11.8%; it is not an unconditional synonym for this 10.0–13.5% Si grade. (Na/Sr) is a modification option, not an element-percent limit.

검토 중인 데이터

항복강도 보류: The original developer handbook prints the sand-cast O parenthetical yield minimum as 70 MPa on PDF p. 34 but 60 MPa on PDF p. 78. The parenthetical values are casting minima at wall thickness ≤20 mm (PDF p. 75). Neither minimum is selected pending issuer clarification; the separate specimen performance range 60–120 MPa agrees.
