Weston Stainless, Midland, UK, is a reputable supplier of high-quality stainless steel products, and they specialize in high-performance welding consumables. Among their notable products is AWS Class E312-16 electrodes, which are part of Grade 312 and are produced in a solid cylindrical form. The electrodes are made of austenitic stainless steel, which are renowned for their high strength, corrosion resistance, and capacity to weld dissimilar metals. E312-16 electrodes contain excellent crack resistance and high mechanical strength, rendering them suitable for welding hard-to-weld material and high tensile strength, and durability required in harsh applications.
AWS Class E312-16 electrodes contain high Chromium (28-32%) and Nickel (8-10%), supplemented by balanced percentages of Manganese, Silicon, and Carbon. These electrodes have a tensile strength of about 800 MPa and an elongation of about 25%, making them highly tough and impact-resistant. They possess good physical characteristics such as a density of about 7.8 g/cm³ and a melting point range of 1400-1450°C. The high resistance of these electrodes to cracking and wear makes them very appropriate for welding processes that undergo high stress, thermal cycling, and corrosive environments.
