Products Description
Durability
In terms of strength, A572 is the clear choice over A36. If the finished structure has to stand up to large amounts of weight, you should consider using the HSLA alloy steel. A36 steel has a minimum yield of 36 ksi, while A572 offers a minimum yield of 50 ksi. The ksi, or kilo-pound per square inch, is a unit of pressure like psi. Unlike PSI, which is ordinarily a measurement for gases, ksi denotes a material's tensile strength or yield strength.
Another important factor in choosing a grade of steel is if the structure needs to stand up to the elements. Steel structures that won't be painted should resist corrosion from exposure to water. In addition to its higher strength, A572 steel also resists corrosion. Because A572 doesn't need painting to resist rusting, it can save material costs and time for outdoor structures. A36 steel, despite being easier to work with and inexpensive, is less corrosion-resistant, meaning it will rust over time if not painted. As a result, manufacturers should avoid this grade of steel for projects that will come into contact with water regularly.
Some finished projects will have to hold up to extremely high or low temperatures. A36 steel is less likely to hold its shape under extreme heat than A572. However, both grades of steel can withstand temperatures up to 750° Fahrenheit. If a structure needs to withstand higher temperatures, mild steel of any kind probably isn't suitable.
