AA M460

Category 
type 
Seamless metal-powder cored wire without slag for M21
applications 
Steel construction, shipbuilding, pressure vessels, mechanical engineering, pipe work, offshore, crane building, heavy transport, lifting equipment etc.
Properties 

Seamless metal cored wire with remarkable stable arc and no spatters. Excelent for use in automated welding applications such as orbital Mag or robotic welding.This wire offers a unique approval class at most third parties that anables you to use only one wire to cover more procedures upto 460N/mm2 yield strenght steels. AA M460 can also be used for constructions that needs post weld heat treatment after welding and still offers mechanical properties confirming 5Y46 class. Due to the seamless production process the hydrogen content is below 3ml/100gr weld metal even after long storage.
