ASME / ASTM SA/A 333 Gr. 6 Heat treatment

[zebmahar]

Hello Guys

According to ASME SA 333, Gr. 6 Product should be Quench and Tempered but we don't have the facility. Any how we do achieve the properties required by the said standard through simple heat treatment furnace. In your opinion, does our product qualify according to the standard?

Regards

zebmahar,
I always suspected the ASME SA 333 is a fake, but you just brought the proof;- you don't need to follow the standard requirements to manufacture the materials with the same properties. You also get a significant saving on the Q&T for your product. I congratulate you for your endeavour, but if I were you, I wouldn't rush to claim patent on your invention, I could hear a few giggles in the background.
Good luck,

Quenching & tempering is not required for SA-333 Gr 6. Per 4.2.1.5, it "may be heat treated...followed by quenching in liquid and reheating to a suitable tempering temperature..."

You need to read all of 4.2.1.
