Process

The production process of Qste500tm steel automotive tubing mainly includes steps such as smelting, continuous casting, hot rolling, cooling, straightening, cutting, and inspection. Firstly, the raw materials are refined into qualified molten steel through smelting processes, and then the molten steel is poured into billets through continuous casting machines. Next, the billets are heated and rolled by hot rolling machines to form square tubes of a certain size. During the rolling process, it is necessary to strictly control the rolling temperature and speed to ensure the dimensional accuracy and surface quality of the square tubes. After rolling, the square tubes need to go through cooling, straightening, and cutting processes, and finally undergo quality inspection to ensure that the products meet relevant standards and requirements.

FAQS

Can Yuantai Derun make 1 2 steel automotive tubing?

Yes,send your inquiry to email:sales..........com

How do I calculate the weight capacity of a automotive square tube?

For automotive square tubes (with equal sides):

W=0.0075 × B × T × (L-2 × T) ×σ

Among them, W is the static load borne by the square tube (kgf), B is the outer length of the square tube (mm), t is the wall thickness of the square tube (mm), and L is the length of the square tube (mm), σ Is the tensile strength of the material (kgf/mm ²）。

2. For solid automotive square tubes:

W=(B × T ²×σ)/ (4) × L)

Among them, W is the load-bearing capacity (kgf), B is the side length (mm), t is the thickness (mm), and L is the length (mm), σ Is the tensile strength of the material (kgf/mm ²）。

It should be noted that the above formula is only applicable to square tubes of standard materials and shapes. When selecting and using them, it is necessary to follow relevant standards and specifications for selection and use. In addition, in practical applications, factors such as the engineering site environment, load type, and support method need to be considered to ensure the stability and safety of the square tube structure.

Can Yuantai Derun supply automotive stainless steel tubing?

Yes,Although Yuantai Derun does not directly produce automotive stainless steel tubing, we can search for reliable suppliers for our customers throughout China.

Can you accept automotive custom tubes?

Yes.we can accept automotive custom tubes.

Can automotive square tube be easily welded together?

1. Welding connection welding is a common method of connecting automotive square tubes. By heating the ends of two automotive square tubes to the melting point, they are fused together to form a whole. This connection method can provide high strength and stability, but requires professional welding technology and equipment.

2. Thread connection is a simple automotive square tube connection method.
