Overview
ASTM A269 TP304L grade covers nominal wall thickness low carbon 304L stainless steel tubing. The ASTM A269 TP304L Tube is designed with an austenite structure that has resistance to general corrosion due to the superior content of nickel and chromium embedded within them. The versatile grade of ASTM A269 TP304L Stainless Steel Tubes work well across low as well as high temperature applications. The robust tubes showcase enhanced strength and resist attacks from a range of reducing agents across stress-induced setups. These tubes are quality assured and supplied to your doorstep within a short span of time due to our connections with the best logistical services.
Specification
ASTM A269/A269M-15a(2019) Standard Specification for Seamless and Welded Austenitic Stainless Steel Tubing for General Service
This specification covers nominal-wall-thickness, seamless and welded austenitic steel tubing for general corrosion-resisting and low- or high-temperature service. All material shall be furnished in the heat-treated condition. The steel shall conform to the chemical composition requirements. Different mechanical test requirements that includes, flaring test, flange test, hardness test, and reverse flattening test are presented. Also, each tube shall be subjected to the non-destructive electric test or the hydrostatic test. Finally the hardness requirements for different grades of tubes are highlighted.
