Its designation, “TP304,” signifies that it is a “Tube, Pipe” made from the austenitic stainless steel grade 304, which is defined by its specific chemical composition and mechanical properties in the ASTM A312 standard. Often referred to as “18-8” stainless steel (18% chromium, 8% nickel), TP304 offers an exceptional balance of corrosion resistance, formability, durability, and cost-effectiveness, making it the default choice for a staggering array of applications.
