Overview

Why choose Stainless Steels?

Stainless steel selection begins with the component environment, required condition, geometry and verification plan. Tianlu reviews these requirements together before confirming a production route.

  • Exposure and corrosion environment
  • Required material condition and treatment
  • Joining, machining and finishing expectations
  • Inspection and documentation requirements

Availability

Stainless Steels options

Standards, material condition, equivalent designations and final availability are confirmed for each project. No equivalence should be assumed without engineering review.

The grades below are representative, not a complete availability list. Final grade, condition and applicable standard are confirmed during engineering review; cross-standard equivalence is not implied.
