HSS Steel Meaning

HSS Steel Meaning

HSS steel has two meanings. In the steel pipe industry, HSS steel meaning eHollow Structural Section. In the cutting tool and machinery industry, HSS imeaning High-Speed Steel.

HSS steel meaning: Hollow Structural Section, primarily used for load-bearing structural steel pipes. It comes in three types: Square HSSRectangular HSS, and Circular HSS. HSS steel can be produced via cold forming or hot forming, adhering to standards such as A500 or EN 10219. Manufactured from low-carbon steel or low-alloy steel, it offers excellent weldability, ductility, and strength to meet engineering requirements.

HSS: High-Speed Steel, a high-alloy tool steel. Due to its stable performance and hardness under high-speed operation, it is commonly used for cutting tools such as drill bits and turning tools. High-Speed Stee contains 10%-20% alloy content, with primary chemical elements including W, Mo, and Co. These elements enhance High-Speed Steel hardness, wear resistance, red hardness, and toughness.
