\u25b6\ufe0e Characteristics:<\/strong><\/h5>\n

LKT-90B9, The weld metal contains 9%Cr-1%Mo and some little Nb,V to improve the creep problem at prolonged high temperature. It\u2019s designed for welding low-alloy steels with high tensile strength and creep-resistance steels such as A355 Grade P91 or similar materials.<\/p>\n

 <\/p>\n

\n

 <\/p>\n

\u25b6\ufe0e\u00a0<\/strong>Applications:<\/strong><\/h5>\n

It is suitable for welding of pipelines in pressure vessels and boilers with operating temperatures up to about 700\u00b0<\/span>C<\/p>\n

 <\/p>\n

\n

 <\/p>\n

\u25b6\ufe0e Notes on Usage:<\/strong><\/span><\/p>\n

1. Use DC(-) current and 100%Argon gas at proper flow rate.
\n2. In order not to derogate the weld metal quality from particle. Be sure to clean up the contaminations on base metal and welding seam.<\/p>\n
