What are the advantages of high speed steel?
Advantages of HSS in general
- Application temperature over 600°C.
- High cutting speeds.
- High strength (high breaking strength)
- Good grindability during production.
- Good regrindability of blunt tools.
- Relatively low price.
What is HSS used for?
High-speed steel (HSS or HS) is a subset of tool steels, commonly used as cutting tool material. It is often used in power-saw blades and drill bits. It is superior to the older high-carbon steel tools used extensively through the 1940s in that it can withstand higher temperatures without losing its temper (hardness).
What are the properties of HSS?
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.
What are the properties and uses of high speed steel?
Broadly, high speed steel excels in hardness and abrasion resistance, with different grades trading for toughness, hot hardness or reduced brittleness. As a result, these alloys see the most use in industrial cutting tools—tool bits, milling cutters, saw blades, drills, taps, broaches and more.
Can HSS cut stainless steel?
High-speed steel tools can be used on stainless steel, but shorter drills are the most effective as they are less susceptible to deflection. The best HSS drills for stainless steel are alloyed with tungsten or molybdenum.
What is HSS e material?
HSS-E is a higher quality material, which is additionally alloyed with cobalt. Metal cutting circular saw blades in this grade of steel are used for materials which are difficult to machine such as VA (stainless) steel or other material grades with higher strength.
Which is better HSS or carbide?
Carbide steel has more high cutting speed and is 4- 7 times higher than high – speed steel. Carbide is much harder, so it has a longer tool life and faster cutting data than conventional high speed steel. HSS tools also cost less than Carbide tools and are often a good solution in high-mix, low-volume applications.
What is composition of HSS?
A common type of high-speed steel contains 18% tungsten, 4% chromium, 1% vanadium, and only 0.5–0.8% carbon. See also heat treating, stainless steel.
Is HSS good for aluminum?
Coatings. Aluminum is soft when compared to other metals. If you’re using high-speed steel (HSS) tooling, look for coatings like titanium carbo-nitride (TiCN). That way you get the lubricity needed for aluminum, but you can spend a little less cash than on carbide.
What is the hardness of HSS?
The alloying elements raise the temperature at which tempering occurs, allowing HSS to be used at temperatures up to about 650°C. Their hardness is limited to 750 HV, adequate for machining most of the common metals, including alloy steels in their unhardened forms.
Which is better HSS or Carbide?
What kind of alloys are used in HSS steel?
There are high speed steels with different alloying additions, which in turn contribute to different tool properties. Carbon, tungsten, vanadium, molybdenum and chromium are the additives used in HSS steels.
What are the pros and cons of HSS tools?
1 HSS tools may cost less, but they wear out much faster than carbide does 2 While the edge may be sharper, HSS tools need replacing more often since they can only be sharpened a few times before it affects the stability of the instrument 3 Will not work on certain high hardness alloys
What are the advantages of using a HSS drill?
Another great advantage of using HSS drills is that the HSS drill can thrive and perform even in old and infirm machine tools with limited power. As power requirement for cutting is directly proportional to cutting speed (with other cutting parameters like feed rate remaining same), use of HSS becomes unavoidable in machines with limited power.
Where does the hardness of HSS come from?
HSS obtains its hardness from its basic structure, which consists mainly of iron and carbon. In addition, alloying additions of more than 5 % are contained, making HSS a high-alloy steel. The name additions HSSE-Co 5 or HSSE-Co 8 indicate the percent of cobalt content.
