Kyaw Stainless, a prominent manufacturer and supplier in Naypyidaw, Myanmar, produces high-quality AWS Class ER308/308H SAW and Flux materials aimed at high-performance submerged arc welding applications. With a strong focus on quality and customer satisfaction, Kyaw Stainless ensures all products meet international welding standards. The ER308/308H wires are designed for welding austenitic stainless steels, providing outstanding mechanical and corrosion-resistant properties. Through advanced production technology and strict quality control, Kyaw Stainless supplies reliable welding consumables used in petrochemical, power generation, and food processing industries, meeting Myanmar’s growing need for durable and effective stainless steel joining solutions.
AWS Class ER308/308H SAW wires mainly consist of chromium (19-21%), nickel (9-11%), and controlled carbon levels—ER308 containing ≤0.08% C and ER308H up to 0.10% C. The flux improves weld bead smoothness and helps with slag removal. Mechanical properties include a tensile strength of about 580 MPa, yield strength around 350 MPa, and elongation of 35%. Their excellent ductility and corrosion resistance against intergranular attack and oxidation make this wire-flux combination well-suited for joining 304/304H stainless steels under high-temperature service conditions.

Used for submerged arc welding of stainless steel, providing strong, durable welds with excellent corrosion resistance, ideal for high-strength, high-temperature applications.
Designed for submerged arc welding of stainless steel, offering superior weld quality, high strength, and excellent corrosion resistance in various industrial applications.
Enhances the welding process by providing a clean, slag-free weld with minimal spatter, offering excellent corrosion resistance and strength for stainless steel applications.
AWS Class ER308/308H SAW and FLUX are commonly applied in petrochemical, power generation, food processing, and marine industries. They are best for welding 304 and 304H stainless steel pressure vessels, boilers, storage tanks, and heat exchangers. Due to their excellent corrosion resistance and high-temperature strength, they can be applied for use in exposure to harsh heat, steam, and aggressive chemical environments. With better weldability and mechanical properties, these fillers provide tough, strong welds in demanding industrial applications where long-term performance is needed.
AWS Class ER308/308H SAW and Flux are intended for welding stainless steels like 304, 304H, and similar grades in chemical, petrochemical, and power plant equipment. These materials are perfect for fabricating storage tanks, boilers, heat exchangers, and pressure vessels that work in high temperatures. The high-carbon ER308H version offers better creep resistance for long-term use in high-heat applications. Additionally, the smooth bead finish and ease of slag removal make it ideal for automatic and semi-automatic welding operations where consistent quality and corrosion resistance matter.
