SHANGHAI SHUNYUN INDUSTRIAL CO., LTD. has been one of the most trusted names in the manufacturing and supply of steel tubing and pipes for over a decade now. Established in 2010, the company has been dedicated to providing high-quality products that are both durable and reliable. Based in Shanghai, China, the company is strategically located in a prime location that allows for easy transportation of its products to customers all over the world.

One of the products that have earned SHANGHAI SHUNYUN INDUSTRIAL CO., LTD. a stellar reputation in the industry is their ASTM A519 4130 low alloy steel tubing. Alloy 4130 is a low alloy steel that possesses excellent strength and toughness, making it ideal for use in various industries such as aerospace, automotive, and defense. The tubing is known for its high tensile strength, durability, and resistance to corrosion, making it a popular choice among manufacturers and engineers.

One of the key advantages of ASTM A519 4130 low alloy steel tubing is that it is easy to work with. Cold working using conventional methods is readily accomplished on this alloy. This means that manufacturers can process the tubing using methods such as cold drawing, bending, and machining to achieve the desired shape and size. The ease in which the tubing can be worked with makes it a popular choice among manufacturers who require complex shapes and designs for their products.

To ensure that the ASTM A519 4130 low alloy steel tubing possesses the desired properties, annealing may be required. Annealing is a heat treatment method that involves heating the material to a specific temperature and cooling it down slowly to improve its ductility and toughness. Alloy 4130 may be annealed at 1550 F for a time long enough to allow thorough heating of the section size. It should then be cooled in the furnace at a rate of less than 50 F per hour down to 900 F, followed by air cooling from 900 F.

Tempering is another heat treatment method that is used to restore some of the ductility that may be lost after the hardening heat treatment and quench. Alloy 4130 is tempered at between 750 F and 1050 F, depending upon the strength level desired. The lower the tempering temperature, the greater the strength.

It is important to note that the 4130 alloy is a through-hardening alloy and should not be case hardened. The alloy possesses excellent machinability and weldability, making it easy to work with and weld.
