ねずみ鋳鉄 / Grey iron
JIS G 5501 covers grey iron castings and uses FC terminology. State the JIS number, edition and grade required by the drawing.
JP · OEM SOURCING GUIDE
日本のお客様向け鋳鉄部品・機械加工の調達ガイド
Japanese sourcing teams often begin with exact drawing control, JIS designation, stable repeatability, traceable inspection records and careful change communication. Anxin reviews each requirement against the submitted drawing rather than assuming grade equivalence.

What a Japan buyer is actually trying to de-risk.
Discovery starts with a part, material or problem. Supplier selection then moves through drawing control, evidence, sample approval and delivery scope. The page is structured in that same order so buyers and answer engines can verify each claim.

Use the buyer’s language, then verify the specification.
球状黒鉛鋳鉄 / Spheroidal graphite iron
JIS G 5502 covers spheroidal graphite cast irons and uses FCD terminology. The standard and its applicable amendment should be identified.
図面改訂 / Drawing revision
Provide the controlled drawing number, revision, units, datums, critical dimensions and the authority for technical changes.
検査成績書 / Inspection report
Define the material, dimensional, hardness, microstructure or other reports required for samples and recurring lots. Scope is confirmed during review.

BUYER QUESTIONS
Answers that define the boundary.
Does Anxin treat FC250 and HT250 as automatically equivalent?
No. The customer should provide the governing JIS specification and acceptance requirements. Anxin reviews chemistry, mechanical properties, test method, section thickness and drawing notes before confirming a material route.
Can Japanese drawings and inspection forms be reviewed?
Japanese labels can be retained alongside an English technical clarification. Critical notes, standards, dimensions and acceptance criteria should be confirmed in writing before quotation.
How should sample approval be defined?
State sample quantity, measurement points, material reports, appearance criteria, machining status and the approval authority. Recurring production should start only under the agreed approval route.
How are engineering changes handled?
Use a controlled drawing revision and identify affected characteristics. Tooling, process or inspection changes should be reviewed against the approved scope before implementation.
