Difference Between Duplex Stainless and Industrial Stainless Steel Pipe
1) Comprehensive mechanical properties better industrial stainless steel pipe, especially plastic toughness, not as industrial stainless steel pipe as brittle sensitive.
2) In addition to stress corrosion resistance, the other resistance to local corrosion is better than industrial stainless steel pipe.
3) Cold processing technology and cold forming performance is much better than industrial stainless steel pipe.
4) Welding performance is also far superior to industrial stainless steel pipe, generally do not need to preheat before welding, after welding without heat treatment.
Compared with industrial stainless steel pipe, duplex stainless steel shortcomings are as follows:
Alloy element content is high, the price is relatively high, the general industrial does not contain nickel.

How to Strengthen the Stability of SSAW Steel Pipe
1) Small and medium-sized steel, wire rod, steel, medium diameter steel pipe, wire and wire rope, etc., can be stored in a well-ventilated shed, but must be under the pad. 2) Some small steel, thin steel, steel, silicon steel, small diameter or thin-walled steel pipe, all kinds of cold-rolled, cold-drawn steel and high prices, easy to corrode the metal products can be stored. 3) Storage of SSAW steel pipe(Spirally Submerged Arc Welded
Shortcomings of Duplex Stainless Steel Pipe
Compared with austenitic stainless steel pipe, duplex stainless steel pipe's shortcomings are as follows: 1) the universality of the application and multi-faceted as austenitic stainless steel, for example, its use temperature must be controlled at 250 degrees Celsius. 2) its plastic toughness than the austenitic stainless steel low, cold, hot processing technology and forming performance as austenitic stainless steel. 3) the existence of moderate temperature brittle area, the need for strict control of
