New specs requires:
Maximum hardness value shall not exceed 310HV10 - this is for the Welding Procedure Qualification.
In previous project acceptance criteria was 350HV10
I believe it can be difficult to achieve 310HV10
Do somebody has such as experience..some advise?
Can somebody advice regarding welding consumable for Carbon steel grade 450
New Project specifications require: content of Boron (B) in deposit weld metal cannot exceed 0.0005% for welding base materials with SMYS of 415 MPa or greater.. Have somebody preformed review of the inclusion of Boron...
thanks for the answer metengr. Why is it minimum temp. not the maximum? sorry if this is stupied question I just dont know a lot about the pressure test. I'm asking about the contaminations from the carbon steel pressure plugs on stainless steel line. I know that the line have to be cleaned...
is there recomendation for the material type for plugs to pressure testing of the welded pipe line made by super duplex material and carbon steel with inconel clad. a specialy with thinking om contamination aspect. Recomendations in standars such as ASTM. if yes where can if find this in standards?
