Chemical & Material Interaction Analysis
Ink is classified as an industrial process chemical (requires verification of concentration and thermal operating envelopes prior to deployment). Used in chemical manufacturing, fluid transfer, and industrial storage systems. When selecting wetted components for Stainless Steel, engineers must account for both concentration-dependent chemical attack and thermal stress:
- Reaction & Failure Mechanism: Triggers progressive mechanical degradation, plasticizer extraction, elastomeric swell, or localized corrosion over multi-day exposure.
- Material Profile (Stainless Steel): Superior mechanical strength, high-temperature tolerance, and complete immunity to organic solvent swelling in ketones, esters, aromatics, and fuels. However, vulnerable to catastrophic localized pitting, crevice corrosion, and chloride stress-corrosion cracking (SCC) in halide acids (HCl, HBr), ferric/cupric chlorides, and sodium hypochlorite bleach.
- Application Scope: Common wetted components include high-pressure process piping, sanitary food/pharma vessels, centrifugal pump casings, heat exchangers, and valve bodies.
