E8018-B3L

8018-B3L is a low hydrogen, low alloy, chrome-moly electrode containing extra low carbon and designed for welding 2-1/4% chromium -1% molybdenum steel. The extra low carbon content of 8018-B3L improves micro structure stability during high temperature service applications such as found in pressure piping or boiler work. 8018-B3L can be used in any position with AC or DC (re verse polarity) and offers good arc stability, low spatter and high deposition efficiency. Excellent mechanical properties and X-ray quality weld deposits.8018-B3L is similar in usage and applications to our 8018-B3. 8018-B3L is most commonly used for castings, forgings and plates of 2-1/4 chromium -1% molybdenum steel, pressure piping such as found in steam power generating equipment, boiler and heat exchanger steel tubes, marine equipment, chemical processing equipment and oil refinery equipment.PREHEATING AND POST-HEATING Depending upon the thickness and hardening characteristics of the work piece, preheating at a temperature between 400-650°F and post heating at 1250-1350°F (for 1 hour) is required. Note: In many cases the lower carbon content of USA 8018-B3L will permit a lower preheat temperature
