Low Alloy & High Strength
ER100S-G
ER100S-G welding wire is an AWS A5.28 high-strength low-alloy solid welding wire classification for applications requiring ER100-strength weld metal and manufacturer-defined alloy chemistry. The G classification does not define one single fixed alloy chemistry, so the actual chemical composition, mechanical properties and application should be verified from the manufacturer's technical documentation and qualified welding procedure.
Low Alloy & High Strength
ER110S-G
ER110S-G is a high-strength low-alloy solid welding wire classified under AWS A5.28. The G classification does not define one single fixed alloy chemistry, so the actual chemical composition, mechanical properties and application should be verified from the manufacturer's technical documentation and qualified welding procedure.
Low Alloy & High Strength
ER120S-G
ER120S-G welding wire is an AWS A5.28 high-strength low-alloy solid welding wire classification for applications requiring ER120-strength weld metal and manufacturer-defined alloy chemistry. The G classification does not define one single fixed alloy chemistry, so the actual chemical composition, mechanical properties, toughness and application should be verified from the manufacturer's technical documentation and qualified welding procedure.
