Is HSS a steel?
Hollow Structural Sections (HSS) are manufactured hollow steel sections, typically of circular, rectangular, or square cross-section. Popular uses include architecturally exposed structural steel, staggered truss and conventional truss structures, and basic column or vertical bracing elements.
What is HSS-e material?
Carbon, tungsten, vanadium, molybdenum and chromium are the additives used in HSS steels. The alloying element cobalt is of particular importance. If the steels have a cobalt content of 5% or 8%, then these steels form their own alloy group, which is designated by the abbreviation HSS-E.
What is high speed steel properties?
High speed steel (HSS) is a tool steel with high hardness, high wear resistance and high heat resistance. High-speed steel is often used in power-saw blades and drill bits.
How is HSS steel made?
Conventional High Speed Steels (HSS) are manufactured with the conventional steel’s melting processing which includes ingots solidification, forging or rolling, heat treatments and final quality inspections.
How do you identify HSS?
Defining High Speed Steel
- High alloy content, primarily tungsten or molybdenum, with lesser amounts of chromium, vanadium and cobalt;
- High carbon content—a minimum of 0.65% by weight, but commonly anywhere from 0.8% to 1.5% carbon content;
- Rockwell hardness of at least 64 HRC at room temperature;
What is HSS made of?
Typically, they consist of carbon steel alloyed with tungsten or molybdenum, together with percentages of chromium, vanadium and cobalt. The alloying elements raise the temperature at which tempering occurs, allowing HSS to be used at temperatures up to about 650°C.
What is HSS tube steel?
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. Rectangular and square HSS are also commonly called tube steel or box section.
What does HSS G mean?
This precision-ground bit made of HSS (high-speed steel) enables up to 40% faster drilling rate and up to 50% lower feed pressure than standard-ground HSS drill bits with chisel edges. …
How much is tungsten in HSS?
These molten alloys contain large amounts of carbide-forming elements, such as chromium (30–33%) and tungsten (10–20%), in a cobalt matrix (38–53% Co) to produce a fine-grained, hard surface of 60–65 HRC made up of complex carbides.
Which is the most common type of HSS steel?
M2 is the “standard” and most widely used industrial HSS. It has small and evenly distributed carbides giving high wear resistance, though its decarburization sensitivity is a little bit high.
How is HSS used in the construction industry?
The use of HSS is growing with popularity all around the world in the building industry and in the United States accounts for approximately 18% of the structural steel market. Popular uses include architecturally exposed structural steel, staggered truss and conventional truss structures, and basic column or vertical bracing elements.
What kind of steel is high speed steel?
High-speed steel is made from W, Mo, Cr, Co, V, and etc elements. And HSS is high alloy steel with high carbon content. Its carbon content is about 0.7%-1.65%. And the alloy content is about 10%-25%. High-speed steel is widely used in all kinds of processing cutting tools.
What are hollow structural sections ( HSS ) made of?
HSS Hollow Structural Sections (HSS) are manufactured hollow steel sections, typically of circular, rectangular, or square cross-section. In the United States, HSS sections conform to either the ASTM Specification A500 or A1085.
