Chemical & Process Industry Forging
Chemical plants attack their own equipment. Grade selection is the entire engineering problem — a correctly specified stainless lasts decades, while the wrong one fails in months at exactly the same cost to buy.

Grade Selection by Media
304 for mild service, 316 wherever chlorides are present, duplex where chloride stress corrosion threatens, and specialist grades for acids. We ask what the medium, temperature and concentration actually are before recommending anything.

Cleanliness and Contamination
Stainless is handled on segregated tooling and storage. A carbon steel smear from shared handling becomes visible rust weeks later — unacceptable in pharmaceutical and food-adjacent process equipment.
Parts We Supply
Process flanges, valve bodies and trim, agitator shafts and hubs, pump components, reactor fittings, sight glass hardware and drawing-specific process components.
Grade Selection by Medium
Chemical plants attack their own equipment, and grade selection is the entire engineering problem. A correctly specified stainless lasts decades; the wrong one fails in months at the same purchase price.
| Environment | Starting-point grade | Note |
|---|---|---|
| General process, no chlorides | SS 304 | Most economical austenitic option |
| Chlorides present | SS 316 or 316L | Molybdenum resists pitting |
| Welded assemblies | 316L | Prevents sensitisation in the HAZ |
| Chloride stress corrosion risk | Duplex | Ferrite phase resists SCC |
| Hardness plus mild corrosion | SS 410 | Hardenable martensitic grade |
Contamination Control in Stainless Manufacture
Stainless handled on tooling shared with carbon steel picks up embedded iron that rusts weeks later on the finished surface. It looks exactly like a grade failure, and in pharmaceutical or food-adjacent equipment it is unacceptable regardless of cause. Stainless work is therefore processed on segregated tooling and storage, with pickling and passivation available where surface condition matters for corrosion resistance. See corrosion problems in forged parts.

Questions Answered
How do you prevent carbon contamination of stainless?
+
Segregated tooling, handling equipment and storage for stainless work, so no carbon steel transfer occurs.
Can you supply pickled and passivated parts?
+
Yes, pickling and passivation are arranged where surface condition matters for corrosion resistance.
Which grade should I use for chlorides?
+
SS 316 as a minimum; duplex where chloride stress corrosion cracking is a realistic risk.
Do you supply agitator shafts?
+
Yes, forged and ground agitator shafts in stainless grades with runout verified.
