What is Stainless Steel ER308H Filler Wires?

Stainless steel ER308H filler wires have a higher carbon content (up to 0.08%) than regular ER308 and are primarily made of nickel (9–11%) and chromium (19–21%), which improves high-temperature strength. Manganese, silicon, and trace amounts of phosphorus and sulphur are other elements. Excellent mechanical qualities are provided by these wires, such as tensile strength exceeding 600 MPa, yield strength approximately 400 MPa, and elongation usually exceeding 30%. Strong, long-lasting, and corrosion-resistant weld joints are guaranteed by ER308H’s exceptional heat resistance, creep strength, and oxidation resistance, which qualify it for service at high temperatures.

Stainless Steel ER308H Filler Wires Uses

For welding 304H and other high-temperature austenitic stainless steels used in elevated temperature applications, stainless steel ER308H filler wires are perfect. Power plants, refinery units, boilers, furnace parts, heat exchangers, and pressure vessels all make extensive use of them. In settings where strength and resistance to corrosion at elevated temperatures are crucial, these filler wires perform exceptionally well. Both manual and automated welding processes can benefit from their stable arc characteristics and low spatter. Because it produces strong, long-lasting welds that can withstand stress and thermal cycling, ER308H is a popular option for crucial fabrication and maintenance jobs.
