The material of “ASTM A182 F304” and “ASTM A182 F304L” are under the same material standard ASTM A182 ,but the only chemical compostion DIFFERENCE BETWEEN THE MATERIAL OF ASTM A182 F304 AND ASTM A182 F304L is that F304L has a slightly lowe carbon content than A182 F304.

 A 182-A182M is the a standard Specification for Forged or Rolled Alloy-Steel Pipe Flanges, Forged Fittings, and Valves and Parts for High-Temperature Service.

They are all a kind of very common forged stainless steel material which can be made for A182 F304 FLANGES AND A182 F304L Flanges.
