Nerf bars come in all shapes and sizes. They provide far more than just good looks and as such, you want to make sure they last. Just like their styles vary in length and appearance, their durability will vary based on the materials they’re built with. Since their main duties include protecting your ride and holding more than 100 lbs of weight at a time, nerf bars are constructed from only the strongest components. From ABS composite to aluminum and steel, the list is extensive when it comes to choosing the best material for your new nerf bars.

In this article, we’ll take a closer look at stainless steel construction and the two major types of stainless steel that exist – T304 and T409. Some types of steel eventually corrode, but when it comes to T304 and T409 stainless steel, you know you’re dealing with the toughest types of steel in the market.

What’s Stainless Steel?

Not all steel is created equal and while stainless might not necessarily mean it will never stain, it does a good job at keeping corrosion at bay regardless of the water damage it may encounter. The level of corrosion a stainless steel object might be able to withstand varies according to how much chromium and nickel are found in the alloys of said object.

Take a look at our Westin Pro Traxx 4” Oval Nerf Bars, for example, they are made to withstand regular car washes and everyday driving. They are available in two options, a polished, stainless-steel finish or a black, powder-coated finish. The price you pay for the stainless-steel finish is almost twice the amount of the powder-coated one, but it comes with a longer warranty because of its known durability.

T409 Stainless Steel

Unless otherwise stated in the product description, chances are your stainless steel nerf bars are constructed using T409 because it is the most widely known and used type of stainless steel. T409 has enough chromium and nickel to keep rust away, so puddles and storms are no threat to T409 nerf bars.

Some stainless steel nerf bar favorites are Dee Zee 4” Oval Nerf Bars, Lund 5” Oval Nerf Bars and Aries 3” Round Nerf Bars.

T304 Stainless Steel

Hands down the toughest stainless steel out there, T304 is almost completely rust-proof. T304 is the highest stainless-steel quality used in the auto industry, the standard, the king of the jungle – you get the point. Containing about 20% chromium and 10% nickel in the alloy, T304 is easy to distinguish because the ferrous metal content is low enough that magnets don’t stick.

A few best-selling nerf bars made with T304 stainless steel include Westin 4” Platinum Oval Nerf Bars, Proz 3” Premium Round Nerf Bars, and Steelcraft 3” Round Nerf Bars.

Now that you’ve read about the differences between T409 and T304 stainless steel, you can choose your next nerf bar wisely. Remember, the tougher the material is, the price will go up. Although you’d be paying more up front, you’ll save more in the long run by going with stainless steel nerf bars. There’s no wrong choice when it comes to T409 and T304, as they’ll both keep you protected over the long haul. Plus, most of our stainless steel nerf bars are backed with a Lifetime Warranty.
