Problems solved by technology

[0002] At present, iron products on the market often have various defects during use. For example, due to low corrosion resistance of iron products during use, iron products are corroded by acid, alkali, air, etc., causing the surface and interior of iron products to be damaged. The structure is gradually destroyed until it is damaged, which greatly shortens the expected life of iron products
In addition, the existing iron products still have low strength and hardness, poor mechanical strength, and low creep resistance, which have greatly restricted the use of iron products.

Embodiment Construction

[0008] The preferred embodiments of the present invention are described in detail below, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, so as to define the protection scope of the present invention more clearly.

[0009] The present invention is a kind of anti-corrosion U-shaped metal pipe. The anti-corrosion U-shaped metal pipe is made of iron, nickel, tungsten, titanium, boron and carbon through six kinds of components. The percentages by weight of the components in the U-shaped metal tube are: the iron accounts for 81.7%-86.2%, the nickel accounts for 5.3%-6.2%, the tungsten accounts for 1.6%-2.3%, and the Titanium accounts for 3.7%-4.6%, said boron accounts for 2.4%-3.5%, and said carbon accounts for 0.8%-1.7%.

[0010] Further, the percentage by weight of each component in the anti-corrosion U-shaped metal tube is specifically: the iron accounts for 82.2%, the nickel accounts for 6.1%, the tungsten a...

Abstract

The invention discloses an anti-corrosive U-shaped metal pipe. The anti-corrosive U-shaped metal pipe is manufactured by six components including, by weight, 81.7-86.2% of iron, 5.3-6.2% of nickel, 1.6-2.3% of tungsten, 3.7-4.6% of titanium, 2.4-3.5% of boron and 0.8-1.7% of carbon. By adding the nickel, the tungsten, the titanium, the boron and the like into an iron blank, corrosion resistance of the manufactured anti-corrosive U-shaped metal pipe is greatly improved, service life is prolonged, and strength and hardness as well as mechanical strength and creep resistance are improved.

Description

technical field [0001] The invention relates to metal products, in particular to a corrosion-resistant U-shaped metal pipe. Background technique [0002] At present, iron products on the market often have various defects during use. For example, due to low corrosion resistance of iron products during use, iron products are corroded by acid, alkali, air, etc., causing the surface and interior of iron products to be damaged. The structure gradually collapsed until it was damaged, which greatly shortened the expected life of the ironwork. In addition, the existing iron products still have low strength and hardness, poor mechanical strength, and low creep resistance, which greatly restrict the use of iron products. Contents of the invention [0003] The object of the present invention is to provide a corrosion-resistant U-shaped metal pipe with high corrosion resistance, long service life, high strength and hardness, high mechanical strength and strong creep resistance.
