ASTM A249 Stainless Steel Welded Tubes

Introduction

ASTM A249 standard is usually suitable for steel tubes in 3.2mm to 304.8m in outside diameter and 0.4mm-8.1mm in wall thickness. Due to its high strength, excellent corrosion resistance and high-temperature resistance, ASTM A249 stainless steel welded tubes are usually used in boiler, superheater, heat exchanger and condenser tubes, etc. Grade TP304, TP304H, TP316, TP316H, TP321, etc. can be provided by us. These grades are intended for high-temperature service.
