Stainless Steel 13-8 PH Condition A vs 13-8 PH-H1100

Stainless Steel · 13-8 PH temper comparison

13-8 PH Condition A and 13-8 PH-H1100 are two conditions of the same stainless steel grade, 13-8 PH: Condition A (solution annealed) versus H1100 (aged 593 °C (1100 °F) for 4 h). The chemistry is identical, so every difference below comes from the condition. 13-8 PH-H1100 is the stronger of the two: yield strength 1,070 MPa (155 ksi) against 827 MPa (120 ksi) for 13-8 PH Condition A, about 29% more; tensile strength follows at 1,170 MPa (170 ksi) vs 1,000 MPa (145 ksi). 13-8 PH-H1100 is the more ductile: elongation 16% versus 13% for 13-8 PH Condition A, and 13-8 PH-H1100 is harder (35 HRC vs 33 HRC). 13-8 PH-H1100 runs hotter in service (480°C vs 425°C continuous).

13-8 PH-H1100Choose it when strength drives the design, or when the part is bent, formed or impact-loaded.
