Product Description:

Ferro manganese

1. Mainly used as alloy additives and deoxidizer in steelmaking.

2. Used as alloy agent ,widely applied to be widely applied to alloy steel, such as structural steel, tool steel, stainless and
heat-resistant steel and abrasion-resistant steel.

3. It also has the performance that it can desulfurize and decrease the harmfulness of sulfur. So when we make steel and cast iron, we always need certain account of manganese.

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.
Q:What is the difference between hard alloy steel and high speed steel?
1, two kinds of material composition is different: the former WC+Co+TiC, etc., the latter is generally C+Cr+W+Mo+v2, forming methods are generally different: hard alloy is powder metallurgy process (of course, some are powder metallurgy high speed steel)
Q:What type of carbide is the most ductile?
Cemented carbide material with tungsten and cobalt carbide toughness is better, at present the carbide grade in the most toughness of YG15. The relation between cobalt content and toughness is shown below. It can be seen that cobalt content and 13%-16% toughness are the best. In this interval, only YG15 cobalt content is 15%.
Q:What is the hardness of YG8 cemented carbide?
The hardness of YG8 cemented carbide produced by Zhuzhou fine drill is 89.5, all of which are made of cemented carbide raw material
Q:With 80 diameter milling cutter,
This belongs to the category of ductile iron, more difficult to process, because the material is hard particles, it is recommended around S=1200 F=400
Q:It is hard alloy steel
Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.
Q:Chengdu which has carbide scrap acquisition point?
Bars of 75000 yuan / kg (Fu Xujian) Zhejiang Zhoushan self-employed waste tungsten 150-200 yuan / kg, Hebei Hengshui Gucheng County Sindh rare metals tungsten tailings 100-300 yuan / ton Guangzhou lechran gold bars 1200 yuan / kg, Zhengzhou Zhengzhou Hongsen tin small PCB tungsten steel drill 160-190 yuan / kg in Zhejiang Taizhou
Q:What is the reason for the metallographic cavity (as shown in the drawing) of cemented carbide?
Too many factors, but according to the shape, size, number and distribution state can be roughly determined what caused by links.
Q:Carbide tool number with a suitable speed of 20
The surface quality is good, the blank diameter is 50MM. Can play around eight hundred rpm. When the car is refined, 1200r/min.Cemented carbide is a kind of alloy material made by powder metallurgy process of hard metal and bonding metal of refractory metal.Hard alloy with high hardness, strength and toughness, good wear resistance, heat resistance, corrosion resistance and a series of excellent performance, especially high hardness and wear resistance of it, even at a temperature of 500 DEG C also remained unchanged, at 1000 degrees C still have high hardness.Hard alloy is widely used as a tool material, such as turning, milling, planing, drilling, boring, used for cutting cast iron and non-ferrous metals.
Q:What kind of material is the alloy drill bit?
the hardness is relatively high, generally above HRC90 degrees, and it is suitable for batch processing and hard processing!
