Tungsten steel

Noun explanation

Alloy steel containing tungsten.Hard and ductile, resistant to high temperatures.It is used for manufacturing cutting tools, gun barrels, gun bodies, armor piercing bullets and so on.

Introduction to the

For steels containing tungsten, the hardness and heat resistance of the steels are significantly higher than that of high-speed steels and some hot die steels, but the toughness decreases sharply.The main component of cemented carbide is tungsten carbide, so it is also called tungsten steel.Tungsten steel belongs to hard alloy, also known as tungsten titanium alloy.Tungsten steel contains about 18% tungsten and has a hardness of 10K, second only to diamond.The hardness of tungsten steel is four times that of titanium and twice that of steel.So it's basically a zero scratch.Because of this, tungsten steel products (tungsten steel has a lot of consumer love, the hardness of this material is similar to natural diamond, not easy to wear out, brightness as a mirror, never fade, and can withstand mechanical impact.Tungsten steel watches are common, with the characteristics of not easy to be worn.

Tungsten steel is mainly used in industrial applications, often used in lathe tools, impact drill bit, glass knife head, ceramic tile cutter, high quality stainless steel smelting is vacuum coating materials, hard not afraid of annealing, but crisp.Rare metals are extremely expensive, costing around 100 yuan for a large piece of tungsten steel as a rubber eraser, and prices have been rising recently.Another use is accessories, such as the tungsten jewelry we come in contact with.Tungsten generally requires a purity of more than 85% to be called tungsten gold.The high purity tungsten gold does not have too many processing methods in addition to grinding, mainly because the hardness of tungsten is too high, generally after grinding tungsten gold jewelry are more texture brightness and luster is the general metal does not have, especially the high purity tungsten jewelry proportion is very large on the body very weight.

Composition structure

Tungsten steel sintering is to press the powder into a blank, then into the sintering furnace heating to a certain temperature (sintering temperature), and keep a certain time (holding time), and then cool down, to get the desired properties of tungsten steel materials.The sintering process of tungsten steel can be divided into four basic stages:

1: removal forming agent and presintering stage, at this stage the sintered body changes as follows: the removal of forming agent, the early stage of sintering with the increase of temperature, molding agent gradually break down, or vaporization, out of the sintered body, at the same time, forming agent more or less to increase carbon sintered body, increases the amount of carbon will vary depending on the type, quantity and sintering process of forming agent of change.The oxide on the surface of the powder is reduced. At the sintering temperature, hydrogen can reduce the oxide of cobalt and tungsten. If the molding agent is removed in vacuum and sintered, the carbon-oxygen reaction is not strong.The contact stress between powder particles was gradually eliminated, the bonding metal powder began to produce recovery and recrystallization, surface diffusion began to occur, and the compressive strength increased.

2: Solid phase sintering (800℃-- eutectic temperature) : At the temperature before the appearance of liquid phase, in addition to continuing the process occurred in the previous stage, solid inverse stress and diffusion intensification, plastic flow enhancement, sintering body appears obvious shrinkage.

3: liquid phase sintering stage (eutectic temperature -- sintering temperature) : When the sintered body appears liquid phase, the shrinkage is quickly completed, followed by the crystallization transformation, forming the basic structure and structure of the alloy.

4: Cooling stage (sintering temperature-room temperature) : In this stage, the microstructure and phase composition of tungsten steel will change with the different cooling conditions. This feature can be used to conduct heat treatment on tungsten steel to improve its physical and mechanical properties.

5. Stress relief: The sintered tungsten steel has uneven internal stress, line cutting is easy to crack.Usually the sintered tungsten steel needs to be cryogenically cooled for 6~8 hours, eliminating 80% of the interior

Above internal stress.Residual stress can be eliminated by natural aging or cryogenic storage in refrigerator for more than 7 days.

Our common tungsten steel

MD40A, MD45A, YG6, YG7, RD50, RD60, CFH40S.YG15, YG20.KG7, KG5, MD10A

General knowledge: Tungsten steel for fragile materials, so in handling, processing, assembly should be particularly careful.Avoid the work piece to bump or crack.
