Why Choose a Stainless Steel Round Bar for Your Project

Selecting the right component materials for a fabrication or construction project is crucial. The wrong materials will lead to the degradation or failure of a project, and the right materials will ensure the project performs well for decades with little to no maintenance. Stainless steel round bars will meet both of these expectations.

Not all metals are created equally. Aluminum will deform and carbon will rust. Stainless steel round bar are strong and will not corrode, and are also clean for applications where the round bar will be visible.

Stainless steel will not corrode. Stainless steel has at least 10.5% chromium, and in the majority of moist and corrosion promoting environments, will self-passivate.

High Strength — Stainless round bars are also well suited for structural components due to their strength.

Professional Appearance — Stainless steel round bars can be finished in either a brushed or polished finish.

Welding — Most grades of stainless steel round bar will be easily welded without the alteration of characteristics of the surrounding material.

304 or 316?

This is the grade selection question of stainless steel round bars for a reason. Both grades are easy to source, but an easy choice may lead to a lot of regret if the application is not well considered.

GradeBest for Key Advantage

304

General fabrication, kitchens, indoor structures

Lower price, more available

316

Marine, chemical, and outdoor

Better resistant to chloride corrosion

316 should be used when projects will be exposed to salt water, be in contact with chemicals, or acid. 304 should be used for the majority of the projects, as it also performs well and is often much cheaper.

Common Applications

Round bars are used in more applications than you may think.

Shafts – shafts for pumps, motors, and conveyor shafts are usually made of machined round bars.

Food Processing Equipment – bars must be made of materials that are easy to clean and that do not rust; these are required in the food processing industry.

Construction and Architecture – the handrails, balustrades, and structural pins all use stainless durability.

Medical – stainless round bars are used for many surgical tools and components of implants.

What to Know before Buying

Take these into account before purchasing stainless steel round bar.

Diameter Tolerance – this matters when you are working a machining project that requires this to be spot on; you will need to specify whether you need a hot-rolled or cold-drawn bar as there are different tolerances.

Certification – request it as a mill test will provide the grade, heat number, and the mechanical properties of the stainless bar.

Cut Lengths – will custom lengths be offered for a reduced price; are standard lengths more economical; reduced lengths will be less waste.

Ask about the finish – this will differ depending on the environment, e.g., bright annealed, black, or polished.

Having reliable bar stock is important for many different reasons that concern more than just the stock. You also want a supplier who can be relied on to certify the grade, tolerances, and specifications. When ordering one bar or many, choosing a supplier who specializes in bar stock saves a ton of guesswork.

An example of a great supplier is Great Metal. They have many levels of stainless steel round bar, different sizes, and even offer bar stock that is cut to length. They also offer stock for both industrial and precision applications.
