Home > Electrodes > AWS Class E330-16 Electrodes
Weston Stainless of Midland, UK, is a reputable supplier of high-quality stainless steel welding consumables, providing high-performance solutions for industrial use. The AWS Class E330-16 Electrodes are engineered specifically to weld stainless steel alloys with similar composition, offering superior resistance against oxidation and high-temperature corrosion. The electrodes come in standard rod shapes and different diameters, ensuring a stable arc and reduced spatter. Fabricated from high-grade stainless steel materials, E330-16 electrodes produce tough welds with high resistance to thermal cycling and are suitable for conditions exposed to severe temperatures and harsh chemical conditions.
AWS Class E330-16 Electrodes have about 34-37% nickel, 17-21% chromium, and negligible carbon content, which provides high resistance to oxidation and carburization at high temperatures. These electrodes possess a tensile strength of approximately 550-700 MPa and yield strength of about 300 MPa with an elongation rate of 30-40%, giving them outstanding mechanical strength and ductility. They possess a density of approximately 8.0 g/cm³ and have a melting range of roughly 1350-1400°C. Their character makes them capable of withstanding harsh thermal conditions without serious degradation

Excellent corrosion resistance for welding stainless steel. They are typically available in diameters ranging from 2.5 mm to 5.0 mm and lengths of 300 mm to 450 mm. The light coating ensures smooth arc stability and ease of operation.
Superior corrosion resistance, heavy-coated electrodes are designed for demanding environments. Sizes generally range from 3.2 mm to 5.0 mm in diameter and lengths of 350 mm to 450 mm. The heavy coating enhances the arc stability and weld quality in challenging applications.
Excellent corrosion resistance and are ideal for shielded arc welding. They come in diameters from 2.5 mm to 4.0 mm and lengths of 300 mm to 450 mm. The shielding provides effective protection against contamination during the welding process.
AWS Class E330-16 Electrodes find extensive applications in applications needing high resistance against oxidation and carburization, for example, furnace parts, heat exchangers, and industrial boilers. They are perfectly suited for the welding of heat-resistant alloys used in the petrochemical, power generation, and metallurgical industries. The electrodes also find application in incinerators, combustion chambers, and chemical plants where strength at high temperatures and resistance against corrosion are critical. Their better mechanical properties guarantee long-term weld integrity in the presence of repetitive thermal cycling and harsh chemical exposure.
AWS Class E330-16 Electrodes come with test certificates guaranteeing compliance with AWS A5.4 and ISO 3581 standards, confirming their mechanical and chemical properties. They are packaged in moisture-proof containers to avoid contamination and ensure weld integrity. They come in different diameters and are shipped in standard or special packaging to suit industry needs, guaranteeing safe handling and timely delivery across the globe.
