EN 1.4849 Stainless Steel vs. ASTM Grade HF Steel

Both EN 1.4849 stainless steel and ASTM grade HF steel are iron alloys. Both are furnished in the as-fabricated (no temper or treatment) condition. They have 70% of their average alloy composition in common. There are 30 material properties with values for both materials. Properties with values for just one material (2, in this case) are not shown.

For each property being compared, the top bar is EN 1.4849 stainless steel and the bottom bar is ASTM grade HF steel.
