ASME SA543 alloy steel plates

SA543 in the standard ASME SA543/SA543M is a kind of Ni-Cr-Mo alloy steel plates material used to fabric high temperature pressure vessels. ASME SA543 have two grades or levels. They are : grade B and grade C. SA543 need to be done the (Quenching + Tempering ) heat-treatment to meet the property requirement in the standard ASME SA543/SA543M.

CONDITION A--Soak at 1900 F (1038 C) for 30 minutes and cool below 60 F (16 C) for complete martensite transformation. CONDITION H 950- Treat Condition A material at 900 F(482 C) for 1 hour, air cool.. CONDITION H925, H1025, H1075, H1100, H1150- Soak solution treated material for 4 hours at specified temperature, air cool, CONDITION H1150M- Soak solution treated material at 1400 F (760 C) for 2 hours, air cool, then re-heat to 1150 F (620 C) for 4 hours and air cool.

ASME SA543 alloy steel plates Successfully welded by common fusion and resistance methods, this alloy should not be joined by oxyacetylene welding. AWS E/ER630 filler metal is recommended if required.
