ASTM A213 ASME SA-213 TP304H Stainless Steel Tubes
 
SA-213 TP304H is an austenitic stainless steel with more Cr and Ni elements, and 1Cr18Ni9 in GB5310-95 in China is similar to this steel. The steel has good structure stability, high endurance strength, oxidation resistance, and good processing properties such as elbow pipe and welding process. However, it is more sensitive to intergranular corrosion and stress corrosion, and it is easy to produce work hardening due to more alloy elements, which makes machining difficult; it has high thermal expansion coefficient and poor thermal conductivity.
 
 
Standard: ASTM A213, ASME SA213
Equivalent Standards: EN 10216-5, DIN 17458, GOST 9941-81, GOST 9940-81

ASTM A213 ASME SA-213 TP304H welding material selection
The welding performance is good, and the manual welding rod uses o102, o107, o132 or e308-15 (American brand); the argon arc welding wire uses h0cr19ni9 or er-308; if it is welded with ferritic materials, it is recommended to use ernicr3 or enicrfe-3 welding wire specified in ASME standard. Solution treatment after welding can improve the thermal strength and intergranular corrosion resistance of the welding head.
