출처 문서의 제목과 조건 설명은 출처 언어 그대로, 공정 항목의 값·보류 사유·검토 메모는 영어 그대로 표시하며 번역하지 않습니다. 숫자, 단위, 질별, 합금 지정도 번역하지 않습니다.

화학 조성

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

Original-supplier Silafont-90 in 2015 and 2016 official documents. Both are one publisher, not two independent references. The current Silafont product page omits this grade, so current availability is not asserted. Mechanical intervals are supplier performance ranges, not universal minima or EN 1706 requirements. Exact wall thickness, specimen size and test temperature are not provided for these rows. Parenthetical casting minima for walls up to 20 mm are withheld pending separate treatment. The overview selection graphic mentions T6 but supplies no condition-bound T6 numerical row; no T6 properties are inferred. Additional processing fields remain for separate review. The supplier physical table applies to heat-treatable alloys in a heat-treated state, but does not name a unique temper for Silafont-90.
