Factory selling Fluid Tube - Alloy structural steel 15CrMo alloy steel Carbon customizable – Lu
Introduction Alloy structural steel refers to steel used as mechanical parts and various engineering components and containing one or several certain amount of alloying elements. Alloy structural steel has suitable hardenability, after suitable metal heat treatment, the microstructure is uniform sorbite, bainite or very fine pearlite, so it has a high tensile strength and yield ratio. (Generally around 0.85), higher toughness and fatigue strength, and lower toughness-brittle transition temper... -
Factory selling Fluid Tube - Tool steel chinese manufacturer 1.2080 D3 AISI D3 DIN 1.2080 GB Cr12 – Lu
Introduction Tool steel is steel used to manufacture cutting tools, measuring tools, molds and wear-resistant tools. Tool steel has high hardness and can maintain high hardness and red hardness at high temperatures, as well as high wear resistance and appropriate toughness. Tool steel is generally divided into carbon tool steel, alloy tool steel and high-speed tool steel. High-speed tool steel is an alloy tool steel that contains C, Mn, Si, Cr, V, W, Mo, Co. And it can be used as a high-speed... -
Factory Free sample High Frequency Welded Pipe - High pressure boiler pipe Custom manufacturers – Lu
Introduction It is a kind of boiler tube and belongs to the category of seamless steel tubes. The manufacturing method is the same as that of seamless pipes, but there are strict requirements on the steel grades used in the manufacture of steel pipes. High-pressure boiler tubes are often in high-temperature and high-pressure conditions when used, and the tubes will be oxidized and corroded under the action of high-temperature flue gas and water vapor. The steel pipe is required to have high d... -
Factory Cheap Hot Silicon Steel Coil - Alloy steel coil structural steel high yield strength – Lu
Introduction Alloy steel coil In addition to iron and carbon, steel is called alloy steel by adding other alloying elements. 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 and adopting appropriate processing technology, special properties such as high strength, high toughness, wear resistance, corrosion resistance, low temperature resistance, high temperature resistan... -
Professional China Low Alloy Plate - 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... -
Manufacturing Companies for Special Steel - Carbon structural steel ASTM A36 Q195 Q215 Q235 For building structur – Lu
Introduction High-quality carbon structural steel is referred to as carbon structure steel. Specifically, its carbon content is less than 0.08%. Compared with ordinary carbon steel, its quality is better, it has strict chemical composition and requires to ensure the mechanical performance index, high-quality carbon structural steel with low content of impurities such as phosphorus and sulfur. The types of carbon steel are divided into three categories according to the carbon content: low carb... -
Factory directly supply High Pressure Fertilizer Pipe - Square rectangular steel pipeQ195 Q235 Q345 Square and rectangular – Lu
Introduction Square tubes are classified according to their cross-sectional shapes: simple cross-section square tubes: square tubes and rectangular tubes. After the process is processed, it is rolled into strip steel. Generally, the strip steel is unpacked, flattened, crimped, and welded into a round tube, then the round tube is rolled into a square tube, and then cut to the required length. According to the production process, the square tube is divided into: hot-rolled seamless square tube,... -
Cheap price Galvanized Steel Pipe - Rectangle pipe Q195 Q235 Q345 Q215 Square and rectangular – Lu
Introduction A steel material that is open at both ends and has a hollow and concentric cross-section, The specifications of steel pipes are expressed by external dimensions (such as outer diameter or side length) and inner diameter and wall thickness. The size range is very wide, from small diameter capillary tubes to large round steel pipes with a diameter of several meters. Round steel pipes can be used for pipelines, thermal equipment, machinery industry, petroleum geological drilling, co... -

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 ... -
Manufacturing Companies for Hfw Steel Pipe - Ductile iron pipe Made in China K9 C30 C40 En545 ISO2531 – Lu
Introduction The essence of cast iron steel pipe is ductile iron pipe. Because Ductile iron pipe has the essence of iron and the performance of steel, it is called this way. The graphite in the ductile iron pipe is in the form of spheroids, and the size of the graphite is generally 6-7. In terms of quality, the spheroidization grade of the cast iron pipe is controlled to be 1-3, and the spheroidization rate is ≥80%, so the mechanical properties of the material itself have been better improved... -
China OEM Galvanized Round Bar - Galvanized H-beam structural steel Q235b Q345b price – Lu
Introduction H-section steel is a kind of economical section and high-efficiency section with more optimized cross-sectional area distribution and more reasonable strength-to-weight ratio. It is named because its section is the same as the English letter “H”. Since the various parts of the H-section steel are arranged at right angles, the H-section steel has the advantages of strong bending resistance, simple construction, cost saving and light structure in all directions. The zin...
