- Common steel pipe materials
There are many kinds of common steel pipe materials, mainly including carbon steel, alloy steel, stainless steel, titanium alloy and so on. Among them, carbon steel is widely used in various fields, alloy steel is widely used in automobile, aviation and other fields due to its high strength and high wear resistance, stainless steel is widely used in medical equipment, food processing and other fields, while titanium alloy is widely used in high-end machinery, aerospace and other fields.
Second, the comparison of the hardness and wear resistance of different steel pipe materials
- Carbon steel
Carbon steel hardness is low, generally between 100-170HB, wear resistance is not very good. In some high acid and alkali corrosive environment easy to corrode, but in some general needs of the occasion, carbon steel thick and cheap make it a good choice.
- Alloy steel
Alloy steel due to the addition of some alloying elements, hardness is higher than carbon steel, generally between 170-250HB, wear resistance is relatively better. The strength of alloy steel is also higher, but if sustained under high temperature environment, there will be so-called “brittle break”. They are widely used in high-strength applications.
- Stainless steel
Stainless steel has a high hardness, generally between 170-240HB, corrosion resistance and wear resistance is relatively good. The strength of stainless steel is relatively low, but its extension and elasticity for the conventional steel several times. There will be a large number of applications in some of the corrosive requirements of the place.
- Titanium alloy
Titanium alloys have high hardness, usually 280HB and above, and relatively good wear resistance. Titanium alloy specific strength is higher than steel, density and light, become a mainstream material in aerospace, high-grade bicycles and scientific instruments and other fields.
Third, the hardest and most wear-resistant steel pipe materials
To summarize, from the hardness and wear resistance considerations, the hardest and most wear-resistant steel pipe material should be titanium alloy. Of course, different fields have different needs, the choice of different types of steel pipe materials will also make a difference.
