Low-alloy steel pipe: Low-alloy steel pipes have an alloy element content of less than 2 %. Characterized by lower cost, it is suitable for some common mechanical and structural purposes that do not require high strength and corrosion resistance.
There is a wide range of alloy steel tubes, according to different combinations of alloying elements, which can produce different performance characteristics to adapt to different needs of use. Here are some common types of alloy steel tubes.
2.Chromium alloy steel pipe;
3.Manganese alloy steel pipe;
4.Nickel alloy steel pipe;
5.Titanium alloy steel pipe;
6.Chromium-molybdenum alloy steel pipe;
7.Carbon-manganese alloy steel pipe;
Classification Based on Manufacturing Process
1.Seamless alloy steel pipe;
2.Welded alloy steel pipe.
1.What is your paying terms?
Our usual paying terms are 30%TT as deposit and balance paid after seeing copy of bill of loading. For clients cooperated for more than one year, we accept 20% prepay. Beside we do business also under D/P and LC terms.
