AWS Chemical Composition

The nominal composition of ER409 weld metal is 12% chromium with Ti added as a stabilizer. This material often is used to weld bare metal of similar composition.

General Hazard Statement: Solid metallic products are generally classified as “articles” and do not constitute a hazardous material in solid form under the definitions of the OSHA Hazard Communication Standard (29 CFR 1910.1200). Any articles manufactured from these solid products would be generally classified as non-hazardous. However some hazardous elements contained in these products can be emitted under certain processing conditions such as but not limited to: burning, melting, cutting, sawing, brazing, grinding, machining,milling, and welding. Products in the solid state present no fire or explosion hazard. Small chips, fines, and dust may ignite readily, though.The following classification information is for the hazardous elements which may be released during processing.
