HCT980 E700 25X20X1 High-Strength Automobile Special Square Tube High-Strength And Durable Square Tube
Material: BS700/980/1300MC produces special square tubes and round tubes for trailers, the usual thickness is 1.0mm to 2.0mm, the usual specifications: 20*40 30*50* 50*50 40*60 30*30* 50*70 40*40 40*80 complete, and other specifications, can be processed according to customer requirements, the highest strength can reach more than 1300MPa, widely used in trailers, automobiles, construction machinery and other industries
Special high-strength plates for semi-trailers, high-strength waterproof side beams, high-strength pillars, high-strength punching scales, high-strength W scales, protective nets, bottom grooves, one-inch high-strength round tubes, and other cold-formed profiles of various specifications are standardized for Chinese cars and are lightweight , Produce high-quality high-strength cold-formed steel.
1. The high-strength pipe reduces the total weight of the trailer pipe by 1/3, reduces the trailer manufacturing cost, and improves the trailer loading quality.
2. Using high-strength materials, taking the technical requirements of trailer tubes as the standard, and processing them through a special process to achieve the same specifications. Use high-strength tubes with a wall thickness of 1.0 instead of ordinary carbon tubes with a wall thickness of 1.5. During use , Its strength is the same as the loaded quality.
3. Compared with ordinary carbon tubes, the inner and outer surface layers of high-strength tubes have stronger anti-rust ability, which provides convenience for transportation and storage, and at the same time avoids the quality degradation caused by the large amount of rust on the inner wall of the tube. ,
4. The welding surface quality of high-strength tubes is higher than that of ordinary carbon tubes. . For example: when the high-strength tube with a wall thickness of 1.0 and a normal carbon tube with a wall thickness of 1.5 are respectively welded to the normal carbon material in the same specification, the quality of the welding surface of the high-strength tube is the same as that of the normal carbon tube, and when welding with the same material , The overall quality is higher, and there is no need to use high-strength welding wire.
5. The hardness of the high-strength tube is higher than 75% of that of the ordinary carbon tube.
6. Reduction degree: tested with the same specification as three meters long, the wall thickness of 1.0 high-strength tube is 30-40% higher than the wall thickness of 1.5 normal carbon tube.
7. Bending strength: tested in units of three meters in length with the same specification, the strength of a high-strength tube with a wall thickness of 1.0 ≥ the strength of a normal carbon tube with a wall thickness of 1.5.
Note: The test proves that the high-strength tube with the same specification and the wall thickness of 1.0 can completely replace the ordinary carbon tube with the wall thickness of 1.5 during the production and use of the trailer.
The use of high-strength steel can not only reduce the weight of the trailer, but also bring better benefits to users to a certain extent, which is in line with the market trend. The use of high-strength steel in the trailer can not only reduce the weight, but also ensure the same strength, and it is even advisable to strengthen the strength of the trailer. However, in the name of "lightweight", some trailer manufacturers reduce or reduce the designation in the configuration, and use non-high-strength steel to pretend to be high-strength steel, which is worthy of our attention.
