Improvements relating to the welding of ingot iron, gray cast iron, cast steel, cast silicon steel and structural steel

摘要

Chromium nickel steel alloys for use as welding rods in welding ingot iron, grey cast-iron, cast steel, cast silicon steel and structural steel contain from 10-30 per cent of chromium and 2-30 per cent of nickel, preferably 25 per cent of chromium, 20 per cent of nickel, and 0,15 per cent of carbon. The alloy may also contain tungsten, molybdenum, titanium, vanadium, and beryllium. Such alloys may contain 18 per cent of chromium and 8 per cent of nickel together with either 4 per cent of molybdenum and 0,15 per cent of carbon or 0,6 per cent of titanium and 0,12 per cent of carbon, or may contain 18 per cent of chromium, 10 per cent of nickel, 0,8 per cent of tungsten and 0,1 per cent of carbon.
