high-speed tool steel
High speed steel abbreviation senior steel or HSS

It is suitable for high speed cutting of high carbon high alloy tool steels.
Its outstanding characteristic is high hardness, wear resistance and thermal rigid (also called red rigid),
When rj temperatures as high as 500 to 600 degrees Celsius, hardness is still no dropped significantly,
Can than with low alloy steel rj higher speed cutting, is mainly used to produce cutting speed is high,
Load weight, high operating temperature of various cutting tools, such as turning, milling cutter, hob, planer knives, pull knife, drills, taps,
Also can be used in the manufacture of hot deformation requirement high abrasion resistance, high temperature, high temperature spring mould bearings, etc.
Execution standard: a standard GB/T 9943-1988
Second-ranking characteristics and applicable scope:
W6Mo5Cr4V2 steel for tungsten molybdenum department general HSS grades
The steel with high toughness and carbide tiny evenly, thermoplastic advantages.
Since resources and price relationship, many countries to replace W6Mo5Cr4V2 steel W18Cr4V and become the main grades of knives.
W6Mo5Cr4V2 HSS toughness and wear resistance, thermoplastic are optimal W18Cr4V and hardness, red, rigid, high hardness and W18Cr4V quite,
Therefore W6Mo5Cr4V2 HSS except for producing various types general tools outside, still can make the large-scale and hot plastic molding tool.
Because W6Mo5Cr4V2 steel high strength, good abrasion resistance, and can produce high load resistance to abrasion parts, such as cold extrusion mould etc,
But at the moment, must be appropriately reduced quenching temperature to meet the strength and toughness requirements. W6Mo5Cr4V2 HSS to oxidation decarburization.
In a hot-working and heat treatment should take note. W6Mo5Cr4V2 steel abbreviation W6 or 6542, molybdenum department is representative of the universal HSS grades .
It contains a variety of alloying elements of high alloy steels, With high hardness and high wear resistance, high fever, rigid.
High  its quench-hardening ability and enough plasticity and toughness and good casting, forging, welding and machining performance, so it plays in tool steels and important position

To introduce
M35 (W6Mo5Cr4V2CO2) is high cobalt high speed steel toughness of steel, mainly used for precision high toughness wear-resistant metal cold die, also can be used for cutting tools and knife in cooling. Steel, high hardness, can be up to 65 HRC, good red hardness, high temperature and high hardness, grinding easily. Made of the steel cutting tools that can cut iron-based high-temperature alloy, casting high temperature alloy, titanium alloy and super high strength steel, etc., but the toughness is a bit poor, quenching temperature should be adopted when the lower limit. Due to grinding can be good, so can be used to manufacture all kinds of high precision complex cutting tool.
W6Mo5Cr4V2CO2 steel code M35. Cobalt is the brand of superhard high speed tool steel, M35 mass fraction of vanadium in steel is not high (1%), high quality, and the volume fraction of cobalt (5%), cobalt can make carbide during quenching heating more dissolved in the matrix, using the high matrix hardness increase abrasion resistance. The hardness of the steel column, hot hardness, wear-resisting and grinding is very good. Heat treatment can reach 65-66 HRC hardness, but also has a special heat treatment, hardness of 65-66HRC, make its cutting performance (especially the intermittent cutting) improve, improve the impact toughness. The steel can be made into all kinds of knives, cutting difficult-to-machine materials when the effect is very good, and because of its good grinding performance. This can make the complex cutting tool, but the lack of cobalt, cobalt high speed steel is expensive, at about five to eight times that of the common high speed steel.
Domestic cobalt high speed steel used in quenching tempering hardness, red hardness, had certain improvement in such aspects as performance, close to or reached the level of imported steel. After quenching and tempering hardness HRC 67 or higher, the uniformity + 0.5% or less. Product specifications: phi is 10 to 150 mm, hot rolling, forging round steel, rectangular, square steel, forgings, etc. According to standard
