Overview
ASTM A213 Grade 314 Seamless Tubes can become very brittle when subjected to prolonged temperatures of 1200-1500 Degree F (649-816 Degree C ). Therefore it is annealed by heating to 1900 to 2100 Degree F (1038 to 1149 Degree C), then water quench or rapidly air cool. Increased level of silicon in Grade WNR 1.4841 Seamless Tubes further improves oxidation resistance at higher temperature. The offered range of tubes is fabricated by using high grade components and modern techniques in compliance with various strength parameters.
