Stainless Steel 1.4319 1/2H vs 1.4319-FH

Stainless Steel · 1.4319 temper comparison

1.4319 1/2H and 1.4319-FH are two conditions of the same stainless steel grade, 1.4319: 1/2H (half hard) versus FH (full hard). The chemistry is identical, so every difference below comes from the condition. 1.4319-FH is the stronger of the two: yield strength 1,100 MPa (160 ksi) against 820 MPa (119 ksi) for 1.4319 1/2H, about 34% more; tensile strength follows at 1,380 MPa (200 ksi) vs 1,080 MPa (157 ksi). In exchange, 1.4319 1/2H is the more ductile: elongation 16% versus 8% for 1.4319-FH, and 1.4319 1/2H is harder (310 HB vs 170 HB). On the shop floor, 1.4319 1/2H welds better (good vs fair).

1.4319 1/2H vs 1.4319-FH — frequently asked

Is 1.4319-FH stronger than 1.4319 1/2H?

Yes. 1.4319-FH has a typical yield strength of 1,100 MPa (160 ksi) against 820 MPa (119 ksi) for 1.4319 1/2H — about 34% more. Tensile strength is 1,380 MPa (200 ksi) vs 1,080 MPa (157 ksi).

Which condition does FabDigit quote by default, 1/2H or FH?

Annealed is the default 1.4319 condition in the FabDigit quote flow (neither 1/2H nor FH). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

Which is easier to machine, 1.4319 1/2H or 1.4319-FH?

1.4319-FH, by a small margin. Both rate fair for machinability — 40/100 against 35/100 for 1.4319 1/2H; for welding the order is 1.4319 1/2H first (good, 60/100) then 1.4319-FH (fair, 50/100).
