Why this combination

Why SS 316Ti in bars

Titanium-stabilised against sensitisationBetter elevated-temperature strength than SS 316LStandard SS 316-type grade in German/EU specifications (1.4571)Same molybdenum-based pitting resistance as 316

Valve and pump makers working to EN drawings specify 1.4571 bar to match vessel and pipe material.

Titanium makes it slightly harder to machine than SS 316L; tooling should allow for that.

Specification

How to specify SS 316Ti bars

Round bars about 3 – 500 mm diameter; hex 6 – 100 mm A/F; square and flat sections to order; lengths 3 – 6 m random or cut to size
