Features & Specifications
[Processing Services]
TIG Welding: Gas Tungsten Arc Welding (GTAW/TIG) for precision welding of tubes, thin plates, and critical joints. Produces uniform, aesthetically clean weld beads with reliable strength.
Pickling: Removes heat-affected-zone oxide scale, weld discoloration, and rust, restoring the original surface finish of stainless steel. Uses eco-friendly formulations.
Passivation: Chemical passivation forms a dense chromium oxide protective layer on the surface, significantly improving corrosion resistance. Compliant with ASTM A967 / AMS 2700.
PTFE Coating: Industrial-grade PTFE coating with excellent non-stick properties, chemical resistance, and low friction coefficient. Food-grade specifications available.
