Problems solved by technology

[0002] At present, iron products on the market often have various defects during use. For example, welding of iron products is difficult due to various reasons during the processing process, and various external factors occur, such as cracking, welding does not melt, etc. , which affects the production of the product, and also has a great impact on the quality of the subsequent product
In addition, the existing iron products still have the disadvantages of low strength and hardness, poor corrosion resistance, and easy oxidation. Various situations 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 an easy-weldable metal pipe. The easy-weldable metal pipe is made of iron, aluminum, nickel, calcium, magnesium, manganese and carbon through processing. The easy-weldable metal pipe The percentages by weight of each component in the formula are: the iron accounts for 85.9%-91.1%, the aluminum accounts for 2.3%-3.2%, the nickel accounts for 0.7%-1.6%, and the calcium accounts for 1.5%. -2.4%, the magnesium accounts for 1.8%-2.7%, the manganese accounts for 1.4%-2.3%, and the carbon accounts for 1.2%-1.9%.

[0010] Further, the percentage by weight of each component in the easy-to-weld metal pipe is specifically: the iron accounts for 86.5%, the aluminum accounts f...

Abstract

The invention discloses an easily-welded metal pipe. The easily-welded metal pipe is formed by processing seven components of iron, aluminum, nickel, calcium, magnesium, manganese and carbon, wherein the weight percentages of the components of the easily-welded metal pipe are as follows: 85.9-91.1% of the iron, 2.3-3.2% of the aluminum, 0.7-1.6% of the nickel, 1.5-2.4% of the calcium, 1.8-2.7% of the magnesium, 1.4-2.3% of the manganese and 1.2-1.9% of the carbon. According to the easily-welded metal pipe, Through addition of the aluminum, the nickel, the calcium, the magnesium and other components into an iron billet, the welding performance of the manufactured easily-welded metal pipe can be greatly improved, thus facilitating the welding of the metal pipe; meanwhile the added components can improve the oxidation resistance, strength, hardness and corrosion resistance of the easily-welded metal pipe.

Description

technical field [0001] The invention relates to metal products, in particular to an easily weldable metal pipe. Background technique [0002] At present, iron products on the market often have various defects during use. For example, welding of iron products is difficult due to various reasons during the processing process, and various external factors occur, such as cracking, welding does not melt, etc. , so that the production of the product is affected, and it also has a great impact on the subsequent product quality. In addition, the existing iron products also have the disadvantages of low strength and hardness, poor corrosion resistance, and easy oxidation. Various circumstances lead to great restrictions on the use of iron products. Contents of the invention [0003] The purpose of the present invention is to provide an easy-to-weld metal pipe with good welding performance, strong oxidation resistance, high strength and hardness, and good corrosion resistance.
