Differences between cemented carbide steel and high-speed steel:(Supplementary Instructions)

Three, different classification
1. Cemented carbide classification
(1) Spheroid
Cemented carbide balls are mainly composed of carbides (WC, TiC) micron powders of high hardness refractory metals. Common cemented carbides include YG, YN, YT, YW series.
Commonly used cemented carbide balls are mainly divided into: YG6 cemented carbide balls. YG6x cemented carbide balls. YG8 cemented carbide balls. YG13 cemented carbide balls. YG20 cemented carbide balls. YN6 cemented carbide balls. YN9 cemented carbide balls .YN12 Carbide Ball. YT5 Carbide Ball. YT15 Carbide Ball.
(2) Rod-shaped body
The main features of cemented carbide rods are stable mechanical properties, easy welding, high wear resistance and high impact resistance.
Carbide rods can be used not only for cutting and drilling tools (such as micron, twiste drills, drills for vertical mining tool indicators), but also as input pins, various roll wear parts and structural materials. In addition, it can be widely used in many fields, such as machinery, chemical, petroleum, metallurgy, electronics and defense industries.
(3) Plate body
Carbide plate, with good durability and strong impact resistance, can be used in hardware and standard stamping dies. Carbide plates are widely used in the electronics industry, motor rotors, stators, LED lead frames, EI silicon steel sheets, etc. All cemented carbide ingots must be inspected strictly and only those without any damage, such as pores, air bubbles, cracks, etc., can be shipped out.
2. Classification of high-speed steel
(1) High-speed steel is classified according to the alloying elements it contains
① Tungsten series high-speed steel (containing 9-18% tungsten);
② Tungsten-molybdenum high-speed steel (containing 5-12% tungsten and 2-6% molybdenum);
③ High-molybdenum high-speed steel (0-2% tungsten, 5-10% molybdenum);
④ Vanadium high-speed steel is divided into high-speed steel with general vanadium content (containing 1-2% vanadium) and high-speed steel containing vanadium (containing 2.5-5% vanadium) according to the content of vanadium;

⑤ Cobalt high-speed steel (containing 5% of cobalt) ~10%).
(2) High-speed steel is classified according to different uses
① Universal high-speed steel: It is mainly used to manufacture cutting tools (such as drills, taps, saw blades) and precision tools (such as hob, gear shaper, and broach) for metal materials with a cutting hardness of HB≤300. The commonly used steel grades are W18Cr4V, W6Mo5Cr4V2, etc.
② Special-purpose high-speed steel: including cobalt high-speed steel and super-hard high-speed steel (hardness HRC68-70), mainly used to manufacture tools for cutting difficult-to-machine metals (such as superalloys, titanium alloys and high-strength steels, etc.), commonly used steel grades There are W12Cr4V5Co5, W2Mo9Cr4VCo8 and so on.
Small modulus carbide solid gear hobbing cutter:
Application industry
Auto parts: wheel drills, rivet hole drills, decorative drills, etc.;
Steam turbine field: Christmas tree milling cutter, profile tool, blade root blade processing tool, etc.;
Aero-engine field: small modulus gear shaper, machining titanium alloy, superalloy tool, etc.

Cemented carbide inserts are made of cemented carbide, which is an alloy material made of hard compound of refractory metal and bonding metal through powder metallurgy process.
Cemented carbide has a series of excellent properties such as high hardness, wear resistance, good strength and toughness, heat resistance and corrosion resistance, especially its high hardness and wear resistance, which remain basically unchanged even at a temperature of 500 °C , still has high hardness at 1000℃

Cemented carbide inserts are mainly made of solid carbide as the base body, and are processed through multiple production processes.
Cemented carbide, also known as tungsten steel, is made of high-quality tungsten carbide + cobalt powder after mixing by formula and sintering. It has high hardness, high strength, high wear resistance and high elastic modulus. It belongs to the powder metallurgy industry. . As the teeth of modern industry, carbide cutting tools play a fundamental role in promoting the development of the manufacturing industry.
Cemented carbides can be divided into ordinary cemented carbides, fine-grained cemented carbides, sub-fine and ultra-fine grained cemented carbides, and newly introduced twin-crystal cemented carbides. According to the main chemical composition, it can be divided into tungsten carbide-based cemented carbide and titanium carbide-based cemented carbide. Tungsten carbide-based cemented carbides include tungsten-cobalt (YG), tungsten-cobalt-titanium (YT) and added rare carbides (YW). The commonly used metal bonding phase such as Tic) and niobium carbide (NbC) is Co. Titanium carbide-based cemented carbide is a cemented carbide with Tic as the main component, and the commonly used metal bonding phases Mo and Ni. Cemented carbide has high hardness (86~93HRA, equivalent to 69~81HRC), second only to diamond, good hot hardness (up to 900~1000℃, maintaining 60HRC); high flexural strength (MPa5100), good impact toughness and chemical inertness with extremely high corrosion resistance and other characteristics that ordinary alloy blades do not have.
