Introduction to carbon steel pipe material characteristics, application areas and manufacturing processes:

1) Material characteristics of carbon steel pipes

1. Composition: Carbon steel pipe is a steel material with carbon as the main alloy element. Its carbon content is usually between 0.18% and 0.25%, and it also contains small amounts of elements such as silicon, manganese, phosphorus, sulfur and other impurities.

1.What is carbon steel plate?
Carbon steel plate, also called carbon structural steel plate, refers to carbon steel with a carbon content of less than 0.8%. This type of steel contains less sulfur, phosphorus and non-metallic inclusions, so it has excellent mechanical properties. Carbon steel plates can be divided into three categories: low carbon steel, medium carbon steel and high carbon steel. The carbon content of low carbon steel is less than 0.25%, the carbon content of medium carbon steel is between 0.25%-0.6%, and the carbon content of high carbon steel is greater than 0.6%. This type of material has certain plasticity, toughness and strength, good machinability, and has good comprehensive mechanical properties after quenching and tempering treatment. However, their hardenability is poor, cracks are prone to occur, and their welding performance is not high. They require good preheating before welding and heat treatment after welding.

As industrial applications have evolved and grown more complex, the piping products and systems that serve them have had to keep pace.

While many pipe manufacturing methods exist, the most prominent discussion in the industry compares electric resistance welded (ERW) vs. seamless (SMLS) steel pipe.

Both ERW and seamless steel pipe manufacturing methods have been in use for decades; over time, the methods used to produce each have advanced. So which is better?

Carbon steel plate usually been considered as the steel that does not contain much alloy steel elements. Generally elements are C, Mn, P, S, Si, besides these there are no minimum limits for elements of Al, Cr, Ni, Mo, V etc.

Recently, Baosteel Marketing Center (Baosteel International) Steel Trading Company has deeply explored user needs and achieved the first order of battery shell materials for Baowu Aluminum Industry.
Since Baowu Aluminum was put into production, the steel trade company has actively investigated the aluminum plate processing capacity and aluminum plate market in the region, understood the demand of downstream industries, cooperated with Baowu Aluminum and the Academia Sinica, started from the existing cooperative users, took the main engine plant as the dimension, investigated the end customers with useful aluminum demand, visited the main engine plants and supporting plants in East China in a timely manner, and collected the demand for automobile aluminum plates. Based on the unit configuration, design capacity, and product price of Baowu Aluminum, Steel Trading Company simulates and calculates the unit marginal contribution of products based on the current mature aluminum plant's operating rate and yield rate.
Regarding the key product of Baowu Aluminum in the future - aluminum sheet automotive panels, the steel trading company actively promotes Baowu Aluminum's aluminum products when visiting steel aluminum shared customers. With the promotion of the international process of automobile lightweight, new aluminum models of joint venture brands have begun to be produced domestically in recent years. With the deepening of the new energy credit system and the continued opening of foreign investment entry barriers for new energy vehicles by the National Development and Reform Commission, the demand for aluminum alloy plates for automobiles has further increased, and the demand for aluminum plates for battery shells in China has also continued to rise.
The Baosteel team conducted point-to-point visits to battery shell manufacturers and had sufficient communication on technology, processing, transportation, and business aspects. Finally, they locked in trial materials for

What is pure aluminum plate? In fact, the material with a higher aluminum content in pure aluminum sheet is one with an aluminum content exceeding 99%. Compared to other aluminum sheet materials, pure aluminum sheet is a common series in traditional industry. Due to the absence of other technical elements, the production process is relatively simple and the price is relatively cheap.
Currently, it is typically the 1050 and 1060 series. Of course, there is more than one model of pure aluminum plate. Let's take a look at the materials of pure aluminum panels.
What is performance? Ordinary pure aluminum panels are cheap, with a price of 1000 series and 10601100 series. These are so-called pure aluminum panels with relatively low strength, and are generally suitable for patterned aluminum panels, photovoltaic panels, indoor decoration, and other post-processing applications. For example, the 5000.6000 series is generally more common in transportation.
Pure aluminum plate is cheap and has many advantages. It can be reinforced with low-density pure copper, making it easier to process large machinery with medium to low hardness. The corrosion resistance and conductive thermal conductivity series are no less than 5000.6000 series. In daily applications, pure aluminum plate and sound absorption function can be used as sound insulation materials. Low strength equipment using pure aluminum plates can also improve aesthetics, as pure aluminum plates look better and more corrosion-resistant by changing color through anodizing or nickel plating.
In addition, pure aluminum panels also have the following general characteristics:
1. Low density: The density of pure aluminum plate is close to 2700kg/m, and the iron density is about 35%.
2. Reinforcement: After cold processing, pure aluminum plate can enhance the strength of the plate, which can be increased by more than twice. Magnesium, zinc, copper, manganese, silicon, lithium can also be added. After heat treatment, alloying and o
