Effect of Metallurgy in hot dip galvanising
Effect of Metallurgy in hot dip galvanising
(OP)
Dear All,
what should be the % of silicon and phospherous in substrate for Hot dip galvanising ?
Does it have an effect of grey shade and over coating in HDG ?
And what is the appropriate hot rolled low carbon sheet for hot dip galvanising as per ASME or ASTM ? Please help .............

There are many papers/articles available on internet for galavanization of hot rolled and cold rolled sheets. Si killed steel cause increased thickness of galvanized layer. See attached file for a tabular comparison but you will find many articles relating to these.
For ASME and ASTM difference, ASME is same as ASTM however is taken from ASTM specifically for pressure vessel design. All the ASME material shall fully comply to ASTM requirements.

Refer above link for detailed study. You will find many similar papers and articles for this issue.

Incorrect statement. ASTM is not the same as ASME. There can be differences where ASME material specification takes exception to ASTM specification.

I agree that ASME material may have some modifications so ASTM may not fully comply to ASME but vice-versa is true.
Please advise as this is my conclusion from other threads on this issue.
