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 coefficient of thermal expansion of cemented carbides?
- The thermal expansion coefficient of cemented carbide is about 6*10^ (-6) / C, and there is a slight difference according to the type of cemented carbide
- Q:What are the types and specifications of carbide cutters?
- Classification and grade of common cemented carbide (example)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 cobalt content.For example, YG8 is a tungsten cobalt carbide that represents an average WCo = 8% and the remainder is tungsten carbideTungsten, titanium and cobalt carbide
- 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:How are cemented carbides separated from the cutting tools?
- Brazing heating to melt after the pain, you can take off!
- Q:We'll drill on the stainless steel column. Which bit is better?
- Carbide drills are suitable for high speed steel
- Q:General carbide and high-speed steel blade cutting speed? (about the range is OK.)
- Carbide cutting tools, cutting speed limit is 100 meters / minute, usually 50-70 meters per minute;High speed steel cutting tool cutting line speed limit is 10 meters / minute, commonly used 5-8 meters / min..
- Q:What type of carbide for punching dies? Better. Where can I buy it?
- Stamping die is divided into cold stamping and hot stamping, need more different uses to choose different characteristics of carbide brand, you can understandZhuzhou same cemented carbide.
- Q:Carbide yk20? What do you mean?
- Cemented carbides YK20, Y represent alloy categories - tungsten cobalt, K20 represents cobalt contentDensity g/cm3:14.30-14.60;The hardness of HRA is more than or equal to 86.5;The shear strength is greater than or equal to N/mm2:2350,Performance and usage: with high toughness and wear resistance, suitable for embedding percussive rotary drilling bit, drilling in hard and tight hard rock.
- Q:What are the three types of commonly used cemented carbides?
- ISO divides cemented carbide into 3 classes: P, K and M.P class (equivalent to China's YT class) carbide by WC, TiC, and Co composition, also known as tungsten titanium cobalt carbide. This kind of alloy is mainly used for processing steel materials.
- 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.
