说明:Thermanit 25/14 EW 309L-17是钛钙型药皮的超低碳Cr23Ni13不锈钢焊条，可交直流两用，由于含碳量低，故在不含Nb、Ti等稳定剂时也能抵抗因碳化物析出而产生的晶间腐蚀。
Well suited for fabricating austenitic/ferritic joints at max.
application temperature 300 °C (572 °F). Stainless, wet corrosion
up to 350 °C (662 °F). Suitable for depositing intermediate
layers when welding clad products. For joining unalloyed/
low alloy steels/cast steel grades or stainless/heat resistant
Cr steels/cast steel grades to austenitic steels/cast steel grades.
For depositing intermediate layers when welding the clad side
of plates of low carbon, unstabilized or stabilized CrNi(Mo,N)
austenitic metals.
用途: 用于合成纤维、石油化工等设备制造的相同类型的不锈钢结构、复合钢和异种钢等构件，也可用于核反应堆、压力容器内壁过渡层堆焊和塔内构件焊接。
