submerged arc welding wires

Hook:
In the fabrication of high-volume, mission-critical structures like pressure vessels, industrial equipment, and heavy machinery, achieving consistent weld quality with high deposition rates is a primary production objective. Submerged arc welding is a process often considered for such demanding applications.
Product Overview:
We supply a comprehensive range of submerged arc welding wires to support diverse industrial fabrication needs. Our portfolio includes wires for carbon steel, low-alloy steel, and a variety of stainless steel grades. These products are designed to be paired with appropriate agglomerated fluxes to form a complete welding system. Our standard submerged arc welding wires are available in diameters of 0.8mm, 1.0mm, 1.2mm, and 1.6mm, packaged on 15 kg spools. We also offer customized specifications and packaging to meet specific project requirements.
Product Selection Guide by Material Type:
1. Carbon & Low-Alloy Steel Submerged Arc Welding wires
These submerged arc welding wires are engineered for general fabrication, structural welding, and high-speed applications where strength and productivity are key. They are typically used with fluxes like SJ101, SJ301, and SJ501.
Common Grades: H08A, H08MnA, H10Mn2, H10MnSi, H08Mn2SiA, H08E, H15Mn, H15A.
Typical Applications: Welding of carbon and low-alloy steels for pressure vessels (e.g., Q245R, Q345R), bridges, shipbuilding, pipelines, and boiler components. Some grades are noted for supporting high-speed, multi-pass welding procedures.
2. Stainless Steel Submerged Arc Welding wires
This series includes austenitic, martensitic, and ferritic grades designed for applications requiring corrosion resistance, high-temperature performance, or specific metallurgical properties.
Austenitic Grades (e.g., ER308/L, ER309/L, ER316/L, ER321, ER347):
Applications: Widely used in pressure vessels, petrochemical plants, fertilizer equipment, food processing machinery, and medical devices for welding materials like SUS 304/L, 316/L, 321, 347. Special cryogenic grades (ER308L, ER316L) are applied in CNG, LNG, and LPG storage and transport systems.
Martensitic & Ferritic Grades (e.g., ER410, ER430):
Applications: Used for welding components requiring wear and corrosion resistance, such as in hydropower stations and specific industrial machinery, for materials like SUS 410, 430.
3. Specialized & High-Performance Submerged Arc Welding wires
This category includes wires formulated for unique challenges, such as dissimilar metal welding, high-temperature service, and applications demanding exceptional toughness.
Dissimilar Metal & Cladding (e.g., ER309, ER310): For joining carbon steel to stainless steel or for overlay welding. ER310 is also used in high-temperature furnace and coking equipment.
High-Toughness & Pipeline Grades (e.g., H08Mn2E, H08Mn2R, CJQ-1): Paired with high-toughness fluxes (e.g., SJ101Q), these wires are used in critical structures like bridges, ships, pressure vessels, and engineering machinery in low-temperature environments.
High-Strength & Other Alloys (e.g., H60Q, H13CrMoA): For welding high-strength, low-alloy steels and specific alloyed materials.
