ASTM A182 F304L Valve

F304L Low Carbon SS (Forged)

ASTM A182 F304L is the low-carbon (≤ 0.

Form

Forged

Max Temp

+425°C (+800°F)

Min Temp

−196°C (−320°F) — suitable for cryogenic service

Category

Stainless Steel

Chemical Composition — ASTM A182 F304L

C ≤ 0.030%, Mn ≤ 2.00%, Si ≤ 1.00%, Cr 18.0–20.0%, Ni 8.0–12.0%, P ≤ 0.045%, S ≤ 0.030%, N ≤ 0.10%. UNS S30403. Yield ≥ 170 MPa.

Temperature Range

−196°C to +425°C (−320°F to +800°F) — note lower max than 316 due to sensitisation limit

Maximum Temperature

+425°C (+800°F)

Minimum Temperature

−196°C (−320°F) — suitable for cryogenic service

Suitable Services

Cryogenic service: liquid nitrogen, liquid oxygen, liquid argon, LNG auxiliary

Pharmaceutical: water-for-injection (WFI), CIP/SIP lines, API synthesis vessels

Food and beverage: dairy, brewing, and bottling service

Nitric acid and other mildly oxidising acids at ambient temperature

General chemical service in non-chloride, non-reducing environments

Pulp and paper: weak liquors and wash water

Not Suitable For

High chloride environments (seawater, brine) — use 316L or duplex

Reducing acids (HCl, H₂SO₄) at any significant concentration — use Hastelloy

Service above 425°C — sensitisation risk; use stabilised grades (321, 347)

Sour (H₂S) service without specific hardness control

Valve Body Applications

Forged valve bodies in pharmaceutical and food-grade applications

Cryogenic ball and globe valve bodies (LN₂, LO₂, LAr service)

Welded valve assemblies in chemical service where PWHA is not practical

Gate and globe valve bonnets in mildly corrosive chemical service

Trim Applications

Stems and packing followers in food-grade and pharmaceutical valves

Ball and seat ring in small-bore 304L chemical ball valves

Typical Valve Types in ASTM A182 F304L

Ball valves: 304L full-bore, Class 150–300, pharmaceutical and cryogenic

Gate valves: Class 150–600 in food-grade and general chemical service

Globe valves: small-bore control valves in pharmaceutical processes

Needle valves: instrumentation in cryogenic and chemical service
