Super Purchasing for Hexagon Steel Pipe - Welded steel pipe Straight Seam Carbon Steel Welded tube – Lu
Introduction Welded steel pipe refers to steel pipes with seams on the surface that are welded by steel strips or steel plates that are bent and deformed into round or square shapes. The blanks used for welded steel pipes are steel plates or strip steels. With the rapid development of high-quality strip continuous rolling production and the advancement of welding and inspection technology, the quality of welds continues to improve, and the variety and specifications of welded steel pipes are ... -
2021 wholesale price Electro Galvanized Steel Sheet - Galvanized steel strip Q235 Q195 SGCC Hot in the Chinese market – Lu
Introduction Galvanized steel strip is a raw material called (zinc, aluminum) that is cold-rolled or hot-rolled, long and narrow strip steel plate is plated to varying degrees with a layer of (zinc, aluminum). Hot-dip galvanizing has the advantages of uniform coating, strong adhesion and long service life. The hot-dip galvanized strip steel matrix undergoes a complex physical and chemical reaction with the molten plating solution to form a corrosion-resistant zinc-iron alloy layer with a comp... -
Cheap price Steel Wire Rod - Free cutting steel alloy AISI 1212 1117 1215 Mould Steel Tool steel – Lu
Introduction Free-cutting steel refers to an alloy steel in which a certain amount of sulfur, phosphorus, lead, calcium, selenium, tellurium and other free-cutting elements are added to the steel to improve its machinability. With the automation, high speed and precision of cutting, it is very important to require steel to have good machinability. This type of steel is mainly used for processing on automatic cutting machine tools, so it is a special steel. Parameter Item Free cutting steel... -
High definition Zn-Al-Mg Coil - Spring steel plate Carbon structure Polished blue spring steel strip – Lu
Introduction As a general-purpose steel, spring steel is used to make springs for automobile and industrial suspensions. Generally, low-alloy manganese and medium/high carbon steels with very high yield strength are used. This allows objects made of spring steel to be prominent In the case of deflection or distortion, it returns to its original shape. For springs subjected to fatigue loads, high requirements are placed on surface finish and internal cleanliness (limiting the number of non-met... -
Good Quality Galvanized Steel Sheet - Electro galvanized coil SECC SGCC Hot Dipped Galvanized Steel Coil – Lu
Introduction Electro-galvanizing, also known as cold galvanizing in the industry, is the process of using electrolysis to form a uniform, dense, and well-bonded metal or alloy deposition layer on the surface of the part. Compared with other metals, zinc is relatively cheap and easy to be plated. It is a low-value anti-corrosion electroplating layer. Because zinc is not easy to change in dry air, and it can produce a basic form in a humid environment. Zinc carbonate film, this film can protect... -
China wholesale Medium Thickness Steel Plate - Alloy steel Carbon high strength high toughness wear resistance – Lu
Introduction Alloy steel, in addition to iron and carbon, also adds other alloying elements, called alloy steel. The main alloying elements of alloy steel are silicon, manganese, chromium, nickel, molybdenum, tungsten, vanadium, titanium, niobium, zirconium, cobalt, and aluminum. , Copper, boron, rare earth, etc. An iron-carbon alloy formed by adding an appropriate amount of one or more alloying elements on the basis of ordinary carbon steel. According to the different added elements, the use... -
Factory Free sample Galvanized Channel Iron – Galvanized round steel pipe gi seamless carbon steel tubes – Lu
Introduction Galvanized steel pipes are divided into cold-galvanized steel pipes and hot-dip galvanized steel pipes. Cold-galvanized steel pipes have been banned, and the latter is also recommended by the state to be temporarily used. Galvanized steel pipes are welded steel pipes with a hot-dip galvanized or electro-galvanized layer on the surface. Galvanizing can increase the corrosion resistance of the steel pipe and prolong the service life. Parameter Item Galvanized round steel pipe ... -
