Stainless Steel Electrodes LKE-9016-B91 E9016-B91

描述

特点

LKE-9016-B91 is a low hydrogen electrode. The weld metal contains 9%Cr-1%Mo and some little Nb,V to improve the creep problem at prolonged high temperature. With stable arc, low spatter and easy slag removal.

应用:

It is suitable for welding of the steel such as ASTM A213-T91, A335 P91, A387 Gr.91,A182 F91.

使用说明:

1.Dry the electrodes at 350-400°C for 60 minutes before use.
2.Do not exceed the range of recommended because over heat input might decrease the impact value.
3.Keep the arc as short as possible.
4.Take the back-step method at the arc starting to prevent blowholes.
5.Preheat the workpiece at 250-350°C and proceed PWHT.
