HORDA 310
ISO 14343 A/B:
W 25 20 I1
AWS A5.9:
ER 310
ГОСТ 2246-70:
GTAW, corrosion-resistant, chromium-nickel rod for welding heat-resistant austenitic steels of the 25% Cr, 20% Ni types. HORDA 310 has good general oxidation resistance, especially at high temperatures, due to its high Cr content. Common applications include industrial furnaces and boiler parts, as well as heat exchangers
