AR450

While many grades of steel are produced to meet a certain yield strength, Abrasion Resistant steel is specifically engineered for surface hardness. Read more about Abrasion Resistant steels here.

Steel Warehouse's main website has a plethora of information about Valast® 450.

1. Why do I want this?

Many fabrications have parts that experience wear. Sliding wear, abrasive wear, surface fatigue, and erosive wear are common in parts that are designed for contact during their service life. Think of parts designed for moving - dump bodies, snow plows, chutes, buckets, etc. When considering service life, there are a few reasons to consider using abrasion resistant grades.

​

  • Wear failure is usually predictable. Unlike overload failure, where failure can happen suddenly, wear implies a progressive loss of mass over time. Using a grade of steel with higher wear resistance means replacing worn parts less often.

  • If wear progress rapidly or beyond the anticipated rate, wear can cause catastrophic failure. Protect against unwelcome surprises by using a more wear resistant grade.

  • Increase the wear resistance allows for lightweighting: parts of a higher grade will wear slower, allowing for thinner material to be used.

2. Will it work?

I'm The biggest concern when switching to a high abrasion resistant grade is formability. With a yield strength above 200 ksi, AR450 requires a 4.5t minimum bend radius.

With a maximum CEV of 0.45, all conventional welding methods can be used.
