Materials for Chemical Processing

Chemical plants handle acids, alkalis, chlorides, solvents and oxidisers at varying temperatures and concentrations, so no single material fits all. Selection moves up a ladder from SS 304L and SS 316L to SS 317L, SS 904L, duplex, 6Mo, and nickel alloys such as 825, 625, C276 and C22 as conditions get harsher.

Which materials are used in chemical processing?

Quick answer

SS 316L Stainless Steel for general process piping and vessels; SS 317L Stainless Steel for higher-chloride and acid streams; SS 904L Stainless Steel for sulphuric and phosphoric acid; Duplex 2205 Stainless Steel for chloride SCC resistance with strength; Hastelloy C276 for hot contaminated acids and wet chlorine.

What are the material challenges in chemical processing?

01

Pitting and crevice corrosion by chlorides

02

Reducing acids (sulphuric, phosphoric, hydrochloric)

03

Stress corrosion cracking

04

Product purity and contamination control

Frequently asked questions

How do I choose between SS 316L, SS 904L and C276?

Based on the acid, concentration, temperature and chloride level. SS 316L handles mild conditions, SS 904L handles sulphuric and phosphoric acids, and C276 handles hot, contaminated or mixed acids. Corrosion data or plant trials should confirm the choice.

Which product forms do you supply for chemical processing?

Pipes, Tubes, Plates, Sheets, Fittings, Flanges, in the grades listed above, from stock or mill-sourced with EN 10204 certificates.

Which standards apply to chemical processing materials?

Commonly ASTM A312, ASTM A240, ASTM B622, ASTM A262, plus project and code requirements.

Do you supply chemical processing projects outside India?

Yes, including Singapore, Malaysia, United States, Canada, United Kingdom, Germany.
