What Is Penetrant Inspection (FPI And LPI)?   Penetrant inspection is a popular detection method because it is relatively inexpensive, can be done remotely, and can be administered on a surface that is oriented in nearly any direction.  Penetrant Inspection may take the form of Fluorescent Penetrant

What Is AOD (Argon Oxygen Decarburization)?   Argon Oxygen Decarburization, frequently referred to as “AOD”, is an advanced technology for the refinement of iron, nickel, and cobalt based alloys.  By melting a charge in a furnace, and then placing it into the AOD vessel, the metal producer

Nickel: Where Does It Come From?   Because of its strength, toughness, and resistance to corrosion, nickel is a key component of stainless steels.  In fact, the majority of the world’s nickel is consumed in the creation of stainless steel.   But where does nickel come from? 

What Is Pitting Resistance Equivalency Number (PREn)?   The Pitting Resistance Equivalency Number (PREn) is an objective way to do an initial comparison of the relative resistance to corrosion of various metals. It is based on a calculation that considers the weight percentage of alloying elements.  

1.2311 and 1.2378, which is one is more suitable for you？ Nowadays, with the development of economic, plastic plays an important role in our daily life. so the plastic mold steel also important for us. Plastic mold steel is mold steel for plastics. Plastic mold materials are

What is incoloy 925 alloy? Introduce incoloy 925 alloy application property element   What is nickel alloy materials? Nickel alloys are metals made from combining nickel as the primary element with another material. It merges two materials to deliver more desirable features, such as higher strength or

408: Good heat resistance, weak corrosion resistance, 11% Cr, 8% Ni 409: The cheapest model (British and American), usually used as car exhaust pipe, is a ferritic stainless steel (chrome steel) 410: Martensite (high-strength chromium steel), good wear resistance, poor corrosion resistance. 416: The addition of sulfur

301: Good ductility, used for molded products. It can also be hardened at machine speed. Good weldability. Abrasion resistance and fatigue strength are better than 304 stainless steel. 302: Corrosion resistance is the same as 304, and the strength is better due to the relatively high carbon

Key Performance Requirements for Steel in Oil and Gas Pipelines   (1) Strength General oil and gas pipelines are designed according to the yield strength of steel. The use of higher yield strength steel pipe, you can improve the working pressure of the pipeline, to obtain better

The difference between carbon steel wire and piano wire   Carbon spring steel wire Carbon spring steel wire is the selection of high-quality carbon steel coils, isothermal quenching by the lead bath and then cold-dialed to strengthen and become. There are three groups by purpose Group B:
