Material of wear-resistant steel pipe for geological drilling

Abstract

The invention relates to a steel pipe material, in particular to a material of a wear-resistant steel pipe for geological drilling, and belongs to the technical field of iron and steel machining. Thematerial of the wear-resistant steel pipe for geological drilling is characterized in that the material of the wear-resistant steel pipe for geological drilling comprises the following components of,by weight, 0.1-0.9% of Be, 0.2-1.4% of Cs, 0.6-2.0% of V, 0.1-0.6% of Ta, 0.3-0.9% of Pt, 3-6% of Al, 1-5% of Sn, 0.2-0.8% of S, 1-4% of C, 2-6% of Si and the balance Fe. According to the material ofthe wear-resistant steel pipe for geological drilling, through compounding of the Be, the Cs, the V, the Ta, the Pt, the Al, the Sn, the S, the C, the Si and the Fe, the prepared steel pipe is good ininternal and external pressure resistance and good in wear resistance, so that the reliability of the steel pipe during deep well and ultra-deep well drilling is guaranteed.

Description

technical field [0001] The invention relates to a steel pipe material, in particular to a wear-resistant steel pipe material for geological drilling, and belongs to the technical field of steel processing. Background technique [0002] The steel pipe is used to transfer fluid and powder, exchange heat and produce mechanical parts and containers, what's more it's a kind of economical steel. From people's daily utensils, furniture, water supply and drainage, gas supply, ventilation and heating facilities to the manufacture of various agricultural machinery, the development of underground resources, guns, bullets, missiles, rockets used in national defense and aerospace, etc. are inseparable from steel pipes. With the continuous advancement of production technology and the improvement of people's living standards, the quality requirements of steel pipes are getting higher and higher, not only higher strength, hardness, corrosion resistance, wear resistance, high temperature res...

AI Technical Summary

Problems solved by technology

The steel pipe material with the above formula has good hardenability, but the internal and external pressure resistance and wear resistance cannot meet the needs of geological drilling.
