TP304N stainless steel tube S30451 ASTM A249 A269 SS tube factory manufacturer.
TP 304N stainless steel tube manufacturer. UNS S30451 T300 welded stainless steel tubing. China 1.4315 SS 304N tube coil exporter.
SUS304N (UNS S30451) is a nitrogen-added grade that exhibits much higher strength(yield strength of a 0.2% offset is particularly high), and provides advantages over SUS
304 concerning the potential of structural designs. DIN 1.4315 Remarkably higher strength at room to high temperatures and higher fatigue strength than that of SUS 304. Corrosion resistance, heat resistance and physical properties similar to those of SUS 304.
APPLICATIONS OF 304N STAINLESS STEEL TUBE
● High-pressure equipment
● Centrifugal separators
● Various equipment employing SUS 304
