Generated from the Hyphae knowledge graph.
Statement: Silicon content range 0.2–2.5 wt%, phosphorus 0.05–2.0 wt%, sulfur <0.06 wt% in composition field.
Needs verification (non-blocking)
These ranges are consistent with general metallurgical knowledge but are not explicitly stated in the verified Wikipedia snapshot. CIT-PI-02 (Fruehan 1999) is cited but Worker does not have direct access. The carbon content range (3.8–4.7%) is the only composition figure directly verified from CIT-PI-01.
