SAW hardfacing flux

[AW]

I am struggling with hardness in my SAW hardfacing flux at present i use 68/8 HCFCR and still cant go beyond 52 HRC

Hi ,

 

Your query is not specific, What’s the base metal (substrate) and the hard facing alloy being considered for deposition? Could you be more specific?

 

Thanks.

Thanks Mr. Goswami for your reply

Here are the details

Base metal is Mild steel plates of 8mm thickness grade IS 2062 and hardfacing alloy I am using is high carbon ferrochromium of 68% ferrochrome and 8 % carbon I am getting a weld deposit of approx 2 to 3% carbon and 15 to 20% chromium. 

What is the best way to mix flux as I also find lot of porosity in the end. 

regards
