[MW:4433] RE: 4430] Material Properties :

Dear Sir,

Present here the basic differences between the Two Materials.

A 351/A 351M – Standard Specification for Castings, Austenitic, Austenitic-Ferritic (Duplex), for Pressure-Containing Parts

 

A 743/A 743M –Standard Specification for Castings, Iron-Chromium, Iron-Chromium-Nickel, Corrosion Resistant, for General Application

Grade, Type,                 Carbon max, Manganese max,   Silicon max,  Phosphorus max,   Sulfur max,   Chromium,      Nickel,         Molybdenum

A743/CF3M,                        0.03,              1.50,                            1.50,                   0.04,                            0.04,             17.0–21.0,        9.0-13.0,      2.0–3.0, 

19 Chromium 10 Nickel, with Molybdenum,

 

A351/ CF3M                      0.03,              1.50,                            1.50,                   0.04,                            0.04,             17.0–21.0,          9.0-13.0,      2.0–3.0,

Subject: [MW:4430] Material Properties :

 

1. A 351 CF3M
2. A 743 CF3M

 

Both material grades are for Casting. Requirement is for Pump Impeller in SS 316LCast Material.

 

What is the diff. between above TWO Materials.
