The description ‘structural steel’ usually applies to a ductile cold-forming steel with yield strengths from around 350 MPa up to 1300 MPa. Steels with higher yield strengths – typically starting at around 600 MPa – are often called advanced high-strength steel (AHSS). 

High-strength steel can be used in thinner dimensions than mild steel and still make the equipment stronger. Bending and welding the steel into a hollow rectangular beam, for example, will give the component a high strength-to-weight ratio.

Reduced thickness makes structural steel components lighter. By upgrading a crane boom from a 650 MPa steel to a 1300MPa steel, new design opportunities open up. A crane boom’s strength can, for example, be increased by 70% for higher lifting capacity while the amount of material required to build the boom is reduced by 40%. 

Upgrading to stronger and thinner steel increases payload and saves fuel in operation. This reduces the equipment’s carbon footprint. When manufacturing, less steel needs to be handled and welding is faster and requires less filler material for more cost- and resource-efficient production.

High-strength structural steel is a highly multi-purpose material. It is used for steel structures that benefit from the high strength and ductility that characterize this type of steel. It also has high toughness, as measured by a Charpy impact test. This steel has properties that follow common standards such as ASTM A1011, ASTM A1018, ASTM A514, EN 10149 and EN 10025.

In construction machinery it is used for vehicle frames and other load-bearing parts. In heavy transport, structural steel is commonly used for chassis beams and crossmembers, utilizing the steel’s strength to reduce a truck’s total weight and fuel consumption.

The lifting industry relies on structural steel to make high-performing mobile and loader cranes. Crane booms can carry more load and reach higher when made with strong steel in thinner dimensions.

Agricultural equipment also benefits from the use of high-strength structural steel. Strong and light equipment has greater loading capacity and is gentler on the soil when moved empty. Wider reach allows it to cover more ground with fewer passes, increasing the farmers’ productivity.

Cars and truck body manufacturers are always looking to reduce weight while at the same time improving vehicle safety. This is an area where ultra-high-strength steel (UHSS) is becoming more and more common.
