The heat treatment of H13 hot steel

H13 is the most commonly used hot work steel, it has higher thermal strength and hardness, wear resistance and toughness, better heat resistance fatigue performance, has been widely used in the manufacture of various forging die, hot extrusion die and aluminum, copper and its alloy casting mold. Hot-working tool steel undertakes a lot of impact […]

The welding of stainless steel-carbon steel clad plate

The clad plate is produced by bonding two or more metals together into a single steel sheet or plate. Stainless steel-Carbon steel clad plates combined the stainless steel and carbon steel material through the explosion and rolling process, which make the metal plate more corrosion resistant, abrasive resistance and high temperature and pressure resistance. But […]

3 tips for Ni-based high temp alloy cutting

In the last article we discussed what’s the high temp alloy, we know nickel-based alloy is the most commonly used high temperature alloy used in aerospace, aviation and other fields at about or above 1000℃. Because it contains many high-melting-point alloy elements such as Fe, Ti, Cr, Ni, V, W, Mo, etc., which forms austenitic […]

What are high temp alloys?

High temp alloy is the alloy based on the element of Fe, Ni and Co, a kind of metal material that can work for a long time under the action of high temperature above 600℃ and certain stress; It has good high-temperature strength, oxidation resistance, corrosion resistance, fatigue performance, fracture toughness and other comprehensive properties. […]

Why Inconel 600 is popular in high temperature and corrosion resistant valve?

Nickel-based alloy Inconel is widely used in the production of high temperature and corrosion-resistant valves. As specified in ASTM UNS N06600, the specified Inconel 600 is specified in ASTM A494 CY‐40. They are mainly used in stress corrosion resistant environments, especially for high concentration chloride media, when the Ni content is greater than 45%, it […]

Classification of corrosion-resisting nickel-based alloys

Alloys with nickel above 50% are known as nickel-based corrosion-resistant alloys. Like Austenitic stainless steel, the microstructure of nickel-based alloys is single-phase austenitic without phase change in solid-state, and the grains of base metal and weld metal cannot be refined by heat treatment. It has excellent corrosion resistance and high-temperature resistance performance that can withstand […]

A complete introduction of Hastelloy B,C,G alloy for chemical industrial

Ultra-low carbon Ni-Cr-Mo alloy is known as Hastelloy alloy. Hastelloy is a trademark of Haynes International company, consist of the letter “HA” in Haynes, “STELL” in STEILITE and “OY” in ALLOYS. As an advanced nickel-based alloy, Hastelloy offers excellent corrosion resistance to a variety of harsh corrosion environments such as wet oxygen, sulfurous acid, strong […]

What’s the Power Metallurgy High Speed Steel?

Powder high-speed steel is a kind of metallurgical steel, which is made from molten steel by high-pressure atomization, through screening, compaction, vacuum sealing and hot-static pressing, and then forged and rolled. Powder metallurgical steel is compacted by uniform and fine carbide particles. It overcomes a series of shortcomings caused by carbide segregation and forms a […]

A brief introduction of mold steel

Last article, we have introduced the “Tool Steel Grades Definition System”. As we all know, tool steels can be classified to many different types according to different standards. According to their detail application, tool steels can be divided into cutting tool steels, mold steels and gauge steels. Here we introduce the classification of mold steel. […]
