What is TP904L?
904L is a highly alloyed， low carbon containing， non-stabilized austenitic stainless steel grade. Copper has been added to the alloy of 904L Stainless Steel Pipe. Hence， its resistance to strong reducing acids such as sulfuric acid is very high.
We focus in manufacturing special size and custom shape products for our clients.
