This specification covers a corrosion and heat resistant cobalt alloy in the form of welding wire. This wire has been used typically as as filler metal for gas-metal-arc or gas-tungsten-arc welding of parts fabricated from similar or dissimilar corrosion and heat resistant steels or alloys, but usage is not limited to such applications.
ASTM A297 HP Cobalt Alloy Castings - ebcastworldDescription. ASTM A297 Cobalt Alloy Castings . Heat Resistant Parts Specimens for joining were cut from the as-cast ingot. Transient liquid phase (TLP) bonding was carried out at the standard solution cycle, using MBF-30 interlayer.
Cobalt alloy is a kind of metal alloys containing cobalt as the base material. Cobalt alloys have excellent high strength and toughness, high-temperature strength and resistance, and good corrosion resistance.

May 22, 2019 · Divided into two major categories of casting and sintering. The cast alloy has high brittleness and low toughness, and has little practical application value. Widely used are sintered alloys, which are generally sintered from tungsten carbide or titanium carbide and cobalt powder and have high hardness, wear resistance and hot hardness.
Heat Treatment of Tungsten Carbide Products - Meetyou CarbideMay 22, 2019 · Divided into two major categories of casting and sintering. The cast alloy has high brittleness and low toughness, and has little practical application value. Widely used are sintered alloys, which are generally sintered from tungsten carbide or titanium carbide and cobalt powder and have high hardness, wear resistance and hot hardness.
Heat resistant sintered hard alloy - Toyo Kohan Co., Ltd.A heat-resistant sintered hard alloy comprises 35% to 95% by weight of a WCoB type complex boride in a cobalt base alloy. The alloy contains 1.5% to 4.1% boron, 19.1% to 69.7% tungsten, optionally to 25% chromium, the balance being cobalt and a maximum of 1% impurities.
Newer alloys, such as HAYNES® 188 alloy and the alloys listed below, are following in its footsteps. The most significant aspect of 188 alloy is the use of lanthanum, a rare earth metal. Very small additions of the rare earth metal provide an order-of-magnitude increase in the oxidation resistance of both nickel- and cobalt-based alloys.

Superalloys - an overview ScienceDirect TopicsA. Nowotnik, in Reference Module in Materials Science and Materials Engineering, 2016 Abstract. Superalloys are heat resistance alloys of nickel, iron-nickel, and cobalt which can be used at high temperatures, often in excess of 0.7 of the absolute melting temperature, frequently operate at temperatures exceeding 1050 °C with occasional working at temperatures up to the value of
Superalloys, or high performance alloys, are alloys that exhibit excellent mechanical strength and creep resistance at high temperatures, good surface stability, and corrosion and oxidation resistance. They typically have an austenitic face-centered cubic crystal structure with a base alloying element of nickel, cobalt, or nickel-iron.
The Cobalt Family of Alloys - Geronimo AlloysMay 16, 2016 · The reason for this is that this alloy is not changed by heat treatment. None of the properties can be changed once the alloy has solidified. These alloys, cobalt 1, cobalt 3, cobalt 4, cobalt 12, and cobalt 6, etc. get their wear resistance at the instant the alloy goes from liquid to solid in the casting process.
Tungsten:Properties, Production, Applications & AlloysDec 08, 2019 · Tungsten-steel alloys are also used in the production of rocket engine nozzles, which must have high heat resistant properties. Other tungsten alloys include Stellite (cobalt, chromium, and tungsten), which is used in bearing and pistons due to its durability and resistance to wear, and Hevimet, which is made by sintering a tungsten alloy powder and is
However, several low-carbon, wrought cobalt-nickel-chromium-molybdenum alloys exist to satisfy the need for a corrosion-resistant cobalt-base alloy. Wear-resistant alloys are those that are made to resist abrasive wear, sliding wear, and erosive wear. They consist mostly of cobalt and chromium but may also contain tungsten or molybdenum and a US Patent for Heat resisting alloys Patent (Patent Tungsten content less that 0.3% will make the alloy fail to attain required high creep strength, however tungsten in excess of 5.0% will spoil the structural stability and ductility. Cobalt is the component not contained in the conventional heat resisting alloy as aforementioned.
