Generally, the phosphorus content does not exceed 0.045%, and the sulfur content does not exceed 0.045%.Brands from various countries that match 16Mn（Q345）steel: A572 Grade50、SM490、S355、EN10025-2 S355.

Stainless steel 321 seamless steel pipe is a pipe made of 321 stainless steel. It belongs to austenitic stainless steel, the main elements are iron, chromium, nickel, and titanium is added. The addition of titanium improves the resistance to intergranular corrosion, making its performance more stable in high temperature environments of 450-800°C. The pipe has good corrosion resistance, high strength, good toughness and plasticity, and is easy to process and weld. It is widely used in petrochemical, aerospace, food processing, medical equipment and other fields, and often implements ASME SA-213/SA-213M, GB/T14976 and other standards.

316 seamless steel pipe is a pipe made of 316 stainless steel. Its main component is iron, and it contains about 16%-18% chromium, 10%-14% nickel, and 2%-3% molybdenum. It has excellent corrosion resistance, especially strong resistance to chloride corrosion, and also has good high temperature resistance, low temperature resistance, creep resistance, processing and welding performance. Its manufacturing processes include hot rolling and cold rolling. It is widely used in chemical, petroleum, marine engineering, food processing, pharmaceutical and other industries. Common implementation standards include GB/T5310-2017.

Hot dip galvanized pipe is a type of steel pipe that has undergone a specialized coating process to enhance its resistance to corrosion. The process involves immersing the steel pipe in a bath of molten zinc, which forms a robust protective layer on the surface. This zinc coating not only provides a barrier against moisture and environmental elements but also offers cathodic protection, ensuring that the underlying steel remains intact even if the coating is scratched or damaged.

A galvanized rectangular tube is a type of steel tubing that has undergone a galvanization process, which involves coating the steel with a layer of zinc. This protective layer serves as a barrier against corrosion, rust, and other environmental factors that can compromise the integrity of the metal. The rectangular shape of the tube provides added structural support, making it ideal for various construction and manufacturing needs.

A galvanized square tube is a hollow structural section made from steel that has been coated with a layer of zinc to protect it from corrosion. The process of galvanization involves immersing the steel in molten zinc, which forms a robust barrier against moisture and environmental elements. This protective coating ensures that the steel remains intact and functional, even in harsh conditions.

Electrogalvanized pipe is a type of steel pipe that has undergone a specialized coating process to enhance its resistance to corrosion. This process involves the application of a thin layer of zinc to the surface of the steel through electrolysis. The result is a pipe that not only retains the inherent strength of steel but also boasts a protective barrier that significantly extends its lifespan, making it an ideal choice for various applications.

Seamless alloy steel pipe is a type of pipe made from alloy steel that is manufactured without any seams or welds. This unique production process involves heating a solid round billet, which is then perforated to form a hollow tube. The tube is then further processed through a series of rolling and drawing steps to achieve the desired size and specifications. Seamlessness significantly improves the structural integrity of the pipe, making it less susceptible to leaks and failures under high pressure and temperature conditions.

Carbon Steel Alloy Pipe is a type of piping made from a combination of carbon steel and other alloying elements. The primary component, carbon steel, is an iron-carbon alloy that is known for its excellent strength and durability. By incorporating additional alloying elements such as manganese, chromium, nickel, and molybdenum, the properties of the steel can be enhanced, resulting in a pipe that is not only robust but also resistant to corrosion, wear, and high temperatures.

A hot rolled alloy tube is a type of metal tube that is produced through a hot rolling process, where metal is heated above its recrystallization temperature and then shaped into a tube. This method not only enhances the material's mechanical properties but also allows for the creation of complex shapes and sizes. The alloy composition typically includes elements such as chromium, nickel, and molybdenum, which contribute to the tube's strength, corrosion resistance, and overall performance.

An aluminum alloy tube is a hollow cylindrical structure made from aluminum and its alloying elements, which are added to enhance specific properties such as strength, corrosion resistance, and machinability. The most common aluminum alloys used in tube manufacturing include 6061, 6063, and 7075, each offering unique characteristics tailored to meet the demands of different applications.

Cold rolled alloy tubes are cylindrical metal products that undergo a specific manufacturing process to enhance their mechanical properties. The term "cold rolled" refers to the method of shaping the metal at room temperature, which allows for tighter tolerances and improved surface finishes compared to hot rolled alternatives. The process involves taking a metal alloy, typically steel, and passing it through rollers to achieve the desired dimensions and properties without the application of heat.

A welded alloy pipe is a type of pipe made from a combination of metals, typically including elements such as nickel, chromium, and molybdenum, which are known for their exceptional strength and corrosion resistance. The manufacturing process involves taking flat sheets of alloy material, which are then formed into a cylindrical shape and welded along the seam. This welding process not only enhances the structural integrity of the pipe but also allows for the creation of longer lengths without the need for joints, reducing potential leak points.

Stainless steel alloy pipe is a type of pipe that is made from a combination of stainless steel and other alloying elements that enhance its properties and performance. Stainless steel itself is an iron-based alloy that contains at least 10.5% chromium, which gives it the properties of being resistant to rust and corrosion. When combined with other metals such as nickel, molybdenum or titanium, the resulting alloy pipe exhibits improved mechanical properties, making it suitable for a wide range of applications.
