SA213 & SA249 TP304/304L

Seamless & Welded Stainless Steel Tubing

 Seamless cold-drawn stainless steel heat exchanger and condenser tubes.

The most common seamless stainless steel tubing is the 300 series of alloys, which are available in varieties of high-performance, corrosion-resistant types and sizes. These stainless steel alloys most commonly include chromium, nickel, and molybdenum, and are ideal for heat exchanger tubing because they are easy to maintain. have good corrosion resistance and can withstand high pressures and temperatures.

 Ameritube is a distributor of carbon and stainless steel seamless tubing and a variety of alloys used in a variety of processes in the oil and gas, power, chemical, marine and defense industries.  Ameritube provides custom tube from ¼” – 3″ outside diameter and .020″ to .100″ wall thickness.

This non-magnetic alloy is the most widely used of all stainless steels and is also among the least expensive. Both 304 and 304L are austenitic stainless steels with approximately 18% chromium and 8% nickel.   Type 304 stainless steel is resistant to moderately aggressive organic acids, such as acetic acid and reducing acids.  In addition, post-welding heat treatment and rapid quenching improve corrosion resistance in this alloy.  Alloy 304 has excellent weldability and forming characteristics and is used for heat exchangers, chemical processing, and milder chemicals.
