符合GB/T17853 TS308L-FC11 相当 AWS  A5.22 E308L T1-1 ISO 17633A T19 9 L P C1 1

产品特性DESCRIPTION

SWE308L为低碳（0.03%）降低了碳化物在晶间析出的可能性，从而在使用稳定剂（如铌或钛）的情况下提高了抗晶间腐蚀的能力。

SWE308L is a low-carbon type (with a carbon content of 0.03%), which reduces the possibility of carbide precipitation at grain boundaries. Thus, when stabilizers (such as niobium or titanium) are used, it enhances the resistance to intergranular corrosion.
