High strength steels are mainly used for structural applications so it is also called structural steel. High strength steel is used in a various variety of applications, most prominent are automotive, heavy machinery manufacturing, energy and power, shipbuilding, aerospace, packaging, and consumer goods.
Considering this, what are the main properties of steel?
The most important properties of steel are great formability and durability, good tensile and yield strength and good thermal conductivity. As well as these important properties the most characteristic of the stainless steel properties is its resistance to corrosion.
Similarly, what is high strength material?
High-strength low-alloy steel (HSLA) is a type of alloy steel that provides better mechanical properties or greater resistance to corrosion than carbon steel. HSLA steels vary from other steels in that they are not made to meet a specific chemical composition but rather specific mechanical properties.
How can the properties of steel be improved?
The strength of steel can be increased by the addition of alloys such as manganese, niobium and vanadium. However, these alloy additions can also adversely affect other properties, such as ductility, toughness and weldability . The more steel is rolled, the stronger it becomes.
What is considered high strength steel?
High-strength steels (HSS) are categorized as 300 MPa tensile strength and above. These types of products have much higher strengths than mild steels and can help reduce thickness and part weight in comparison to mild steel parts.
