ASME AND ASTM

ASME AND ASTM

ASME AND ASTM

(OP)
I am in the process of obtaining some 304 stainless for weld certification samples. My company calls out ASME SA240 304 STAINLESS on our Weld Procedure Specification. The stainless I received a quote on was listed as ASTM A276, ASTM A479, & QQS-763. Does this mean that I need to obtain different materials? Does it not matter?

RE: ASME AND ASTM

I think sa240 is a plate spec... I think the others are bar specs... not sure, but dont you need to weld plate for certifications for the tests?

also maybe you can use the astm a240 stuff if it says in the asme section II that the sa240 is identical to the astm spec... it would say it right at the begining... but I dont know about for a procedure or welder qualification if you can use the astm material... better wait for another comment... I have limited experience level with this, so I'll be anxious to see what others have to say

RE: ASME AND ASTM

Generally, a type like 304 would be in the same group numbers and all regardless of whether it was bar, plate, sheet, pipe, or what.  Check Section IX to confirm.

Most material that meets an ASTM specification is going to meet the corresponding ASME standard as well.  See if the supplier has mill test reports for the material, which may show it is dual or triply certified for various specifications.  Or check stencils on the plate/bar if there are any.

RE: ASME AND ASTM


Type 304 stainless steel is a T 300 Series Stainless Steel austenitic. It has a minimum of 18% chromium and 8% nickel, combined with a maximum of 0.08% carbon. It is defined as a Chromium-Nickel austenitic alloy.

It is shiny

Magnets don't work very well on it.
