A182 F22 Cl2. is not there. A 336 F22 has better chemistry control w.r.t. S & P compared to A 182 though mechanical properties are same at room temp. and also elevated temperature performances. Before accepting just check latest code edition of ASME section II-D line items for this two and can move ahead with your approval. A336 will be costly. almost similar. >Hi Dears >I am not a material specialist . >I am a equipment designer.
