Priminox Overseas is a known manufacturer of SS 304 / 304L / 304H Pipes, which is the most common stainless steel. 304 Seamless Pipes contains both chromium and nickel metals as the main non-iron constituents. SS 304 Welded Pipes is readily brake or roll formed into a variety of components for applications in the industrial, architectural, and transportation fields. 304L Welded Pipes is a sought after material for use in severely corrosive conditions. A213 SS 304L Seamless Pipes is the most versatile and also widely used alloy in the stainless steel family. Due to its controlled carbon content,. ASTM A312 SS 304H Seamless Pipes provides improved high temperature strength when exposed to temperatures above 800 Degree F. ASTM A249 304H Welded Tubes is an austenitic chromium-nickel steel alloy and the greater carbon content delivers an increased tensile and yield strength. ASTM A358 304LN Welded Pipes is a low-carbon, higher nickel and nitrogen alloyed alternative to 304 with improved strength and low-temperature toughness.
