16Mn is a low-alloy high-strength structural steel: the carbon content is 0.1%-0.25%, and the main alloying elements manganese, silicon, vanadium, niobium and titanium are added; its total alloy content is less than 3%. According to the strength, it is divided into 4 levels of 300, 350, 400 and 450MPa. There are mainly Q295, Q345, Q390, Q420, Q460. "Q" is the capital letter of the Chinese pinyin of the word "Qu" for yield, and the subsequent number is the minimum yield point (σs) value of the brand, and the subsequent symbols are based on the content of impurity elements (sulfur, phosphorus) in the steel from high to high. Low and with the change of carbon and manganese elements, it is divided into A, B, C, D and so on. Among them, A and B grade steel are usually called 16Mn. According to the strength, it is divided into 4 levels of 300, 350, 400 and 450MPa. There are mainly Q295, Q345, Q390, Q420, Q460. A material in 16Mn seamless steel pipe. A name for Q345B seamless steel pipe in the past. The current name is: Q345B seamless steel pipe, and the similar materials are Q345C, Q345D, Q345E, and the quality grade symbols A B C D E represent different requirements for impact tests. The impact test temperature is +20 degrees 0 degrees -20 degrees 40 degrees. 16mn seamless steel pipe is a low-alloy high-strength structural steel with a carbon content of 0.1%-0.25%, and the main alloying elements manganese, silicon, vanadium, niobium and titanium are added; its total alloy content is less than 3%. According to the strength, it is divided into 4 levels of 300, 350, 400 and 450MPa. There are mainly Q295, Q345, Q390, Q420, Q460. : The change of manganese element is divided into A, B, C, D four and so on. Among them, the chemical composition of A and B grade steel is usually called 16Mn seamless steel pipe: C: 0.12~0.20; Mn: 1.20~1.60; Si: 0.20~0.55; Tensile strength: 470~660 N/mm2; ~345 N/mm²; Elongation: 21%. hot rolled or normalized 16Mn seamless steel pipe and 16MnR, 19Mng merged into Q345R. Q345R is an ordinary low-alloy steel, which is commonly used in boilers and pressure vessels. The delivery status is divided into: hot-rolled or normalized. It is a low-alloy steel with low Mn content. The performance is similar to 20G (412-540), the tensile strength is slightly stronger (450-655), and the elongation is 19-21%, which is worse than 20G's greater than 24%. Q345R process reference standard GB713-2008. 16Mn seamless steel pipe is an ordinary low-alloy steel, which is commonly used in boilers and pressure vessels. It is hot-rolled or normalized. It is a low-alloy steel with low Mn content. The performance is similar to 20G (412-540), the tensile strength is slightly stronger (450-655), and the elongation is 19-21%, which is worse than 20G's greater than 24%. 16Mn seamless steel pipe is a special plate for pressure vessels with a yield strength of 340MPa. It has good comprehensive mechanical properties and process properties. The content of phosphorus and sulfur is slightly lower than that of ordinary 16Mn steel. In addition to the requirement of higher tensile strength and elongation than ordinary 16Mn steel, impact toughness is also required. It is the most widely used and used steel plate for pressure windows in my country. use The special steel grade used for bridges is "16Mnq", the special steel grade for automobile girders is "16MnL", and the special steel grade for pressure vessels is "16MnR". This kind of steel relies on adjusting the amount of carbon (C) to improve the mechanical properties of the steel. Therefore, according to the level of carbon content, this kind of steel can be divided into: Low carbon steel - the carbon content is generally less than 0.25%, such as 10, 20 steel, etc.; Medium carbon steel - the carbon content is generally between 0.25 and 0.60%, such as 35, 45 steel, etc.; High carbon steel - the carbon content is generally greater than 0.60%. Such steels are generally not used in the manufacture of steel pipes. main features Good comprehensive performance, good low temperature performance, cold stamping performance, good welding performance and machinability.

Zhengde hot-rolled seamless steel pipe is a long strip of steel with a hollow section and no joints around it. The steel pipe has a hollow cross-section and is widely used as a pipeline for transporting fluids, such as pipelines for transporting oil, natural gas, gas, water and certain solid materials. Compared with solid steel such as round steel, seamless steel pipe is lighter in weight when the bending and torsional strength is the same. It is an economical section steel and is widely used in the manufacture of structural parts and mechanical parts, such as oil drill pipes and automobile transmission shafts. , bicycle racks and steel scaffolding used in building construction, etc. The use of seamless steel pipes to manufacture ring parts can improve the utilization rate of materials, simplify the manufacturing process, save materials and processing hours, such as rolling bearing rings, jack sets, etc., which have been widely used in steel pipes. Hot-rolled seamless steel pipe is also an indispensable material for various conventional weapons. Gun barrels, barrels, etc. must be made of steel pipes.

Our Advantages
Three-roll pipe mill The seamless steel pipe produced by the three-roll mill for hot-rolling seamless steel pipe has high precision. Because of the cross-rolling with the mandrel, the rolling action is repeated many times in one pass, which greatly improves the accuracy of the wall thickness and is not easy to produce. Defects such as scratches, ears, and green lines; the flexibility in production is large, and the pass size can be changed with the help of the clutch of the roll.
Adequate inventory Standing inventory of carbon seamless tubes, seamless special-shaped tubes, alloy seamless tubes, precision tubes. Various types of seamless steel pipes with a specification of 5-426*0.5-60mm and a length of 2-16m. The cold-rolled precision bright tubes produced by our factory have smooth appearance, uniform wall thickness, no oxide layer, and high precision. The inner hole of the steel pipe can be divided into round type, spline type, plum blossom type, etc. It is widely used in automobiles, motorcycles, electric power, petrochemicals, ships, aerospace, bearings, pneumatic components, oil cylinders, boiler equipment, medical equipment, fitness equipment and other industries.
Attention to detail No matter how to choose the hot-rolled seamless steel pipe, its quality cannot be ignored. It must be noted that there should be no defects on the surface, such as small cracks or scars, etc., and that the thickness of the pipe wall is the same to ensure uniformity. The physical comparison is still very important. Only after the basic comparison of the physical objects is done, can the steel pipes that meet the needs be selected. The processing technology of each seamless steel pipe is different, which will also affect its application field. Now it is generally processed by cold drawing and hot rolling, and the processing effect of the two and the application of steel pipes will also have certain differences.
Applicable scene Hot-rolled seamless pipes specifically include low and medium pressure boiler steel pipes, high-pressure boiler steel pipes, seamless steel pipes for ships, petroleum cracking steel pipes, seamless steel pipes for high-pressure fertilizer equipment, oil jacket steel pipes, pipeline steel pipes, hollow sucker rods, and ordinary fluid steel pipes. , structural seamless steel pipes and imported alloy steel pipes, etc., with rich varieties and complete specifications, widely used in petroleum, chemical, electric power, boilers, ships, machinery and other industries, and have been sold all over the world.
Quality first: production and inspection in strict accordance with production standards; Price advantage: discounts based on real market prices; Transaction security: There will be no loss of customer funds; After-sales guarantee: the customer's problem is our problem; Long-term cooperation: quality assurance, price advantage, sincere service can last for a long time.
