ASTM 904L Stainless steel pipe/tubes

Product Description

Product description
1.Mateials : **4L steel
it is high nikel and molybdenum austenitic stainless  acid ressistant steel. As it contains high contents of chrome,molybdenum and copper,it has excellent activation and passivation transformation ability,with low corrosion rate in the passivation area(because of high chrome).Meanwhile,it's with good pitting corrosion resistant performances and good stress corrosion resistant performace.It has good corrosion ressistance in non-oxidizing acids such as sulfuric acid ,acetic acid and phosphoric acid ,and has good pitting corrosion resistance in neutral solutions containing chlorides.
