What’s urea grade stainless steel?

Urea grade stainless steel is a kind of austenitic stainless steel specially for use of urea industry. Derivatives such as CO2, NH3, NH2COONH4, (NH2)2CO, etc. in the process of urea production are not highly corrosive when they exist alone, but the reactant formed when they are mixed together will cause strong corrosion to the equipment.

The effect of rare earth elements in cooper and its alloy

Rare Earth Elements (REE) is a group of metals for short, which including 17 kinds of Elements: 15 lanthanides, that is lanthanum (La), cerium (Ce), praseodymium (Pr), neodymium (Nd), promethium (Pm), samarium (Sm), europium (Eu), gadolinium (Gd), terbium (Tb), dysprosium (Dy), holmium (Ho), erbium (Er), thulium (Tm), ytterbium (Yb), lutetium (Lu), and two other Elements […]

What is copper alloy 110?

110 Copper is UNS commercial pure grade number and its full name is C11000, also known as electrolytic tough pitch copper(ECP).  It offers excellent electrical conductivity, thermal conductivity and good processability. Usually speaking, copper 110 contains 99.99% copper and oxygen-free, because the trace oxygen is likely to cause “hydrogen embrittlement” and should not be processed […]

H13 tool steel heat treatment

Hot-working AISI H13 tool steel offers high hardenability, excellent wear resistance and hot toughness, has been widely used in hot forging dies, pressure dies casting tools, extrusion tools, hot shear blades, stamping dies, plastic mold and aluminum alloy die casting dies, is the most commonly used hot-worked die steel. The H13 steel made by electroslag remelting […]

Advantages of H13 tool steel made by ESR process

For high-quality tool steel, steel mills generally adopt the smelting processes such as furnace refining, vacuum treatment, vacuum smelting, powder spraying and electro slag re-melting to reduce the content of harmful elements such as oxygen, hydrogen and inclusions in steel. Hot-working AISI H13 tool steel offers High hardenability, excellent wear resistance and hot toughness, has […]

Titanium and its alloy polishing methods

Titanium and its alloy have low density and excellent strength and weight ratio, good corrosion resistance and high mechanical strength, but expensive production cost. Titanium and titanium alloy grinding and polishing’s low efficiency make its microscopic structure change because the excessive severe cutting and polishing process will create a mechanical twin in the alpha phase. […]
