Kobelco FAMILIARC LB-52-18 is a low-hydrogen electrode with a high deposition rate for mild steel and 490 MPa high tensile steel. It is an excellent choice for a variety of applications. It produces the weld metal of excellent toughness and crack resistibility because of the characteristic peculiar to the low hydrogen type electrode.
“L” stands for low hydrogen, while “B” symbolizes a slagshielding covered electrode. “52” refers to the typical tensile strength of deposited metal at the time the electrode was developed. “1” shows that it can be used in all positions, while “8” is the designation for “iron powder, low hydrogen” as in the AWS E7018 specification.
Since it’s development in 1962, LB-52-18 has seen its features refined and its markets expanded. Kobe Steel pursues keen quality control in order to maintain the excellency of LB-52-18 produced in Japan and overseas. The maintenance of quality is an important factor in the high reputation LB-52-18 has persistently earned in such diverse fields as machinery, steel structures, bridge construction and shipbuilding.
