The difference between ASTM 304 stainless steel pipe and GB304 stainless steel pipe
00CR19NI10 (304 stainless steel tube China national standard GB / T14976-2002) and ASTM TP304 stainless steel pipe element distinction and contact
00CR19NI10 (304 stainless steel tube China National Standard GB / T14976-2002) chemical elements are as follows:
304 stainless steel pipe element content C≤0.03 Ni8.00～12.00 Cr18.00～20.00，Mn<=2.0 Si<=1.0 S<=0.030 P<=0.035;
TP304L American National Standard ASTM A312 standard ASTM A213 standard chemical elements are as follows:
304 stainless steel pipe element content C ≤ 0.035 Ni8.00 ~ 12.00 Cr18.00 ~ 20.00, Mn <= 2.0 Si <= 1.0 S <= 0.030 P <= 0.045;
The difference between the C content and P content; the Chinese standard C content and P content relative to the US standard ASTM A312 standard lower;
304 stainless steel tube 18Cr-8Ni- low carbon as a low C 304 stainless steel tube, in general, its corrosion resistance and 304 just similar, but after welding or eliminate stress, its resistance to grain boundary corrosion is excellent; In the case of heat treatment, good corrosion resistance can be maintained at a temperature of -196 ° C to 800 ° C. Used in anti-grain boundary corrosive requirements of high chemical, coal, oil industry, outdoor open-air machines, building materials, heat-resistant parts and heat treatment difficult parts
