Louis Metals is a premium supplier of Titanium Grade 4 Bars and Rods, providing exceptional strength and endurance for the most demanding uses. Grade 4 titanium is the strongest of all commercially pure grades and provides superior corrosion resistance in oxidizing and mildly reducing conditions. Being extremely strong, it‘s predominantly utilized in medical, aerospace, and marine applications. At Louis Metals, our Grade 4 bars are manufactured under strict quality controls, ensuring consistent material properties and tight dimensional tolerances. With reliable stock, fast delivery, and competitive pricing, we’re your trusted partner for Grade 4 titanium rod supply in the USA.
Titanium Grade 4 is composed of 99% titanium with controlled amounts of oxygen, iron, carbon, and nitrogen. It provides high tensile strength of about 550–600 MPa and yield strength of 485 MPa. Grade 4 has good corrosion resistance, especially in marine and oxidizing chemical environments, and good biocompatibility. Although less formable than lower grades, it still has high durability and weldability. With its combination of strength and resistance to corrosion, it is the choice for applications requiring high mechanical performance and chemical resistance without alloying additions.
