Is A182FGR.304/304+HF available?

Reply #22011-12-08

304+HF is 304 cladded with cemented carbide, right?

A182 F304 is forged 304 HF; HF is probably an abbreviation for hard face, meaning surface hardening, which involves welding in alloys or something similar

What the poster provided is the specification for the valve materials: the body is made of Bonne:ASTM A182F Gr.304; the wedge is made of A182.Gr.304+HF. The internal components of the valve are forged from 304 stainless steel, while the valve seat is made of 304 stainless steel with cemented carbide.

Reply to 4# yuzhilicn: I saw it in the \"Handbook for the Installation and Design of Process Piping in the Petrochemical Industry\" – there is no mention of GR. What is the difference between A182F304 and A182F304GR?
