Q:Is nickel base alloy hard alloy?: 2, YT--- tungsten cobalt titanium alloy products, applicable to coarse, carbon steel and alloy steel uneven section in interrupted cutting when the YT5 rough planing, semi finishing, discontinuous surface rough milling and drilling.

Q:What is the resistivity of the yg13 cemented carbide?: Three, technical parameters of YG13 tungsten steel1, WC and other alloy composition content%:87.2 and CO content%:13.3 density g/cm3:14.2.4 hardness HRA:90.5.5 、 grain size um:0.6 ultra-fine grain alloy.6. Flexural strength MPa:4000.7 thermal expansion coefficient 10-6/0C:5.8.8. Modulus of elasticity GPa:460.

Q:What does WC refer to in cemented carbides?: Of or relating to an alloying element that is tungsten carbide.Tungsten cobalt carbideThe main ingredients are tungsten carbide (WC) and binder cobalt (Co).The brand is from "YG" ("hard cobalt" Pinyin prefix) composition and percentage of average amount of cobalt.For example, YG8, a tungsten cobalt carbide represented by an average WCo=8% and the remainder of tungsten carbide.

Q:My uncle is a hard alloy round bar. Can you tell me where to use an alloy round bar?: I have some hard alloy round bars (tungsten steel) and high speed steel round rods (all used for cutting tools). Now I want wire cutting, laser, diamond, wire cutting

Q:Where does Tianjin sell yt30 carbide tool?: Now there are the same, express, everything is not afraid. I am the agent of Zigong the Great Wall brand cemented carbide, quality assurance, definitely authentic.

Q:Compare the advantages and disadvantages of high speed steel and cemented carbide: Must be in a hardened state, in high speed steel iron, chromium, tungsten and carbon forming hard carbide can improve the wear resistance of steel (hardness of HRC6468). Another part of tungsten dissolved in the matrix, increase the hardness of steel red.High speed steel can reach 650 degrees of red hardnessHigh speed steel has good strength and toughness, cutting edge is sharp after grinding, and its quality is stable. It is used to make small and complex cutting tools

Q:Method for assembling hard alloy cold heading die: If it is made of hard alloy cold die core and the steel bushing assembly, depends on the heat treatment hardness you cold die steel sleeve to be, if not steel heat treatment, direct heat bushing, the amount of interference for hard alloy core diameter of about 0.6%, if the steel heat treatment to HRC40 about the amount of interference for hard alloy core diameter about 0.3%.

Q:What are the features of cemented carbide YG8 knives?: Pig iron and non-ferrous metal processing. Can also be used in general stainless steel rough processing

Q:How hard is the carbide knife?: Cemented carbide has high hardness, high temperature resistance and good red hardness. It can still maintain good cutting performance at high temperature about 1000 degrees centigrade.

Q:What is the heat treatment process of cemented carbide?: The common heat treatment process of steel bonded carbide is spheroidizing annealing, quenching and tempering.1, spheroidizing annealing die steel bonded carbide matrix is steel, as the alloy tool steel, need to be spheroidizing annealing treatment, can machine processing. The process of spheroidizing degradation is: heating 850~890 DEG C, holding 4h, and cooling the furnace to about 730 DEG C, holding 6h, the furnace is cold, and the air cooled below 500 degrees centigrade,2, the purpose is to make the quenching matrix transforms into martensite, obtain high mechanical properties, due to poor thermal conductivity, preheating, hard steel bonded carbide in carbide phase of austenite grain growth to deter, and the dissolution of carbide in the matrix alloy, iron and hinder the diffusion of carbon atoms, of austenite the grain growth plays an inhibitory effect, so the steel bonded hard alloy quenching overheating less than alloy tool steel, quenching temperature can be higher, the time may be longer, usually for WC type steel bonded hard alloy, quenching temperature of 1020~1050; for TiC type steel bonded hard alloy, quenching temperature is 950~1000 DEG C; G type steel bonded cemented carbide phase with high speed steel, quenching temperature of 1200~1280.3, steel bonded hard alloy die after quenching tempering should be timely, especially the large die should be timely, in order to eliminate quenching stress, prevent mold cracking, while tempering can adjust the organization to obtain the mechanical properties required, tempering temperature often take 180~200 C, 2h insulation, high toughness, high temperature tempering can be used as 500~650 C, but the need to avoid the brittle temperature zone at 250~350 DEG C, high temperature tempering, the carbide precipitation and residual austenite transformation, there will be two hardening, but high temperature tempering will cause precipitation of lead carbide link impact toughness decreases.
