Stainless Steel 1.4372 1/2H vs 1.4372 1/4H

Stainless Steel · 1.4372 temper comparison

1.4372 1/2H and 1.4372 1/4H are two conditions of the same stainless steel grade, 1.4372: 1/2H (half hard) versus 1/4H (quarter hard). The chemistry is identical, so every difference below comes from the condition. 1.4372 1/2H is the stronger of the two: yield strength 800 MPa (116 ksi) against 570 MPa (82.7 ksi) for 1.4372 1/4H, about 40% more; tensile strength follows at 1,080 MPa (157 ksi) vs 900 MPa (131 ksi). In exchange, 1.4372 1/4H is the more ductile: elongation 25% versus 14% for 1.4372 1/2H, and 1.4372 1/2H is harder (300 HB vs 255 HB).
