Valve Materials • Global Standards
Four Common Valve Materials & the International Standards They Meet
Do clients keep double‑checking the material spec and asking, “Does this meet our national standard?” This embedded guide clears it up—at a glance. We break down Ductile Iron, Stainless Steel, Carbon Steel, and Brass: their common grades and the key standards accepted across the U.S./EU, Japan/Korea, Middle East, Southeast Asia, and more.
What you'll get in this quick read
Typical grade names and equivalents you can quote with confidence.
Regional standards by market (ASTM/EN/JIS/KS/ISO), including common callouts.
Pro tip: confirm the country and standard first to avoid rework and returns.
Scope
Valves • Bodies • Trim
Markets
US/EU • APAC • MENA
1) Ductile Iron (DI)
ASTM A536: 65-45-12, 60-40-18
EN 1563: GJS‑400‑15, GJS‑500‑7
JIS G5502: FCD450, FCD500
USASTM A536 • tensile & elongation focused.
EUEN 1563 • GJS + numbers for grade naming.
JP/KRJIS G5502 / KS D 4302 • FCD grades commonly used.
MENA/SEATypically adopt ASTM or ISO.
2) Stainless Steel
Austenitic: 304/316 (F304/F316)
Cast: CF8 / CF8M
Duplex: 2205 (UNS S31803)
USASTM A351 (cast) • A182 (forged).
EUEN 10283 • EN 10088 • e.g., 1.4308 ≈ CF8, 1.4408 ≈ CF8M.
JP/KRJIS G4303 / G5121 • SCS13 (≈ CF8), SCS14 (≈ CF8M). KS D 3595 aligns.
MENA/AsiaASTM and EN widely accepted.
3) Carbon Steel
Cast: A216 WCB
Forged: A105 • Low‑Temp: LF2
Plate: A516 Gr.70 • A36
USASTM A216 (cast) • A105 (flanges/forgings).
EUEN 10213 • EN 10028 • e.g., 1.0619 equivalence in use.
JP/KRJIS G5101 • common grade: SCPH2. KS D 3562 aligns.
MENAOften follow ASTM or ISO.
IndiaIS 2062 (structural steels) referenced for related components.
4) Brass
C36000 (free‑cutting)
C37700 (forging brass)
C63200 (aluminum brass)
USASTM B16 (forgings) • B62 (cast) • e.g., C83600, C37700.
EUEN 1982 • CW617N • CW602N common for valves/fittings.
JP/KRJIS H3250 • CAC406 • CAC203. KS D 5301 aligns.
MENA/AsiaASTM or ISO generally recognized.
IndiaIS 319 often used for low‑pressure water systems & fittings.
Bottom line: ASTM, EN, JIS, and ISO are the core frameworks in global trade. Confirm the
country + standard with your client
before you quote—this prevents rework, returns, and makes you look undeniably professional.
