Easy-to-Weld Wear-Resistant 8620 Alloy Steel Rods

Yield Strength: 55,000 psi
Hardness: Rockwell B85 (Medium)
Heat Treatable: Yes
Max. Hardness After Heat Treatment: Rockwell C60
Fabrication: Cold Worked
Specifications Met: ASTM A108

While the low carbon content makes 8620 alloy steel easy-to-weld, it's the nickel, chromium, and molybdenum content that provides wear resistance.

Easy-to-Weld Wear-Resistant 8620 Alloy Steel Sheets

Yield Strength: Not Rated
Hardness: Not Rated
Heat Treatable: Yes
Max. Hardness After Heat Treatment: Not Rated
Fabrication: Hot Rolled
Specifications Met: ASTM A829

Made of 8620 alloy steel, these sheets have low levels of carbon that make them easy to weld. High nickel, chromium, and molybdenum content make them resistant to wear. For even greater wear resistance, you can harden their surface with heat treating. They’re often used for wear plates and structural supports. These sheets have been manufactured to meet ASTM standards for quality and performance.
