Abstract The effect of time and green inhibitor addition in 1 M HCl on API 5L steel X52 and X65 impact resistance is studied. The concentration of green inhibitor of 3, 5 and 10 % is produced by extract of compound for natural plant. Charpy V specimens are manufactured by special machine and covered by special resin. The immersed specimens are then subjected to high velocity impact with energy 150 J. The concentration of green inhibitor of 5 % resulted in optimum properties, with 42 % improvement in peak load and 32 % increase in elongation. Keywords: impact testing, green inhibitor concentration, API 5L steel |
