ER 2209 Stainless Steel TIG Wire

What are the key chemical compositions and mechanical properties of ER 2209 Stainless Steel TIG wire?

ER 2209 stainless steel TIG wire contains a particular chemical composition as well as mechanical properties that make it ideal for welding tasks. The primary constituents for an ER-2209 TIG wire would be chromium which ranges between 21.5% to 23.5%, thereby improving its anti-corrosion ability; nickel makes up around 6.5% to 7.5% of the alloy enhancing the stability of the joint through imparting strength; while molybdenum constitutes 2.5% to 3.5% promoting more pitting plus crevice corrosion resistance on top of other factors. Lastly, nitrogen comprising approximately 0.1% -0.2% enhances both the strength and toughness of this alloy.

In terms of mechanical properties, the most commonly exhibited by an ER-2209 TIG Wire include tensile strengths of approximately 750 to 950 MPa and yield strength ranging between 550 and 650 MPa. Additionally, the material has superior elongation with respect to stress before breakage, which is roughly between 25% and 35%. These beneficial mechanical and chemical properties ensure confidence of ER2209 stainless steel TIG wire use in critical engineering applications including those requiring demanding welding jobs.
