What does HSS flat mean?
A hollow structural section (HSS) is a type of metal profile with a hollow cross section. The term is used predominantly in the United States, or other countries which follow US construction or engineering terminology.

What does a high Young’s modulus mean?
Young’s modulus is a measure of the stiffness of an elastic material, and it is defined as the ratio of stress to strain. Rocks with low Young’s modulus tend to be ductile and rocks with high Young’s modulus tend to be brittle.
What is the range of tensile strength of structural steel?
Steel material is divided into three categories: Normal strength: Yield stress is about 240 MPa, tensile strength about 360 MPa. High strength: Yield stress is about 340 MPa, tensile strength about 470 MPa. Extra-high strength: Yield stress is about 450 MPa, tensile strength about 550 MPa.
What is the hardness of HSS?
Combining molybdenum, tungsten and chromium steel creates several alloys commonly called “HSS”, measuring 63–65 Rockwell “C” hardness.
What is the difference between A500 Grade B?
The specified yield strength of A53 Grade B is 35 ksi. That’s over a 30% increase in yield strength. Therefore, A500 round HSS have greater strength-to-weight ratios than A53 pipes.
What is A500 grade steel?
A500 Tubing ASTM A500 (Also known as A-500) carbon steel tubing is a standard specification for cold-formed welded and seamless carbon steel structural tubing in round, square and rectangular shapes. ASTM A500 is the most common specification in North America for Hollow Structural Sections (HSS).
What does Young’s modulus tell us?
The Young’s modulus (E) is a property of the material that tells us how easily it can stretch and deform and is defined as the ratio of tensile stress (σ) to tensile strain (ε).
What is the mechanical properties of steel?
Steel has a number of properties, including: hardness, toughness, tensile strength, yield strength, elongation, fatigue strength, corrosion, plasticity, malleability and creep.
Is 2062 a Grade B?
Alloy IS 2062 GR B is the micro-alloy that helps in manufacturing the micro-alloyed plates, sheets, and sections that are used in the industries. This is the way that the alloy is provided in the killed and semi-killed conditions that are there in the industrial working environment.

What is HRC of HSS?
Rockwell hardness of high-speed steel – AISI M2 depends on heat treatment process, but it is approximately 65 HRC. Rockwell hardness test is one of the most common indentation hardness tests, that has been developed for hardness testing.
What is the difference between TS and HSS?
What is the difference between a tube shape (TS) and HSS? Structurally, there is no difference. The Steel Tube Institute, an organization representing the manufacturers of hollow structural sections, initiated the change from “tube” to “HSS” in 1997 to conform to their designation practices.
What is the difference between hot rolled and cold rolled?
The main difference between hot and cold rolled steel is in how they are processed. Hot rolled steel is steel that has been rolled at high temperatures, while cold rolled steel is essentially hot rolled steel that is further processed in cold reduction materials.
What is the grade of ASTM A500?
ASTM A500 is the current market leader for HSS materials. Material is produced to Grade C, which provides a minimum yield strength of 50 ksi. They are widely available in many sizes, shapes and wall thicknesses in service centers throughout North America.
What is A500 material?
A500 carbon steel structural tubing is only manufactured from materials that match the criteria for carbon steel. The chemical composition for A500 is mostly iron with added carbon, manganese, phosphorus, sulfur, and copper.
