說明:Thermanit 25/14 EW 309L-17是鈦鈣型藥皮的超低碳Cr23Ni13不銹鋼焊條,可交直流兩用,由于含碳量低,故在不含Nb、Ti等穩定劑時也能抵抗因碳化物析出而產生的晶間腐蝕。
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: 用于合成纖維、石油化工等設備制造的相同類型的不銹鋼結構、復合鋼和異種鋼等構件,也可用于核反應堆、壓力容器內壁過渡層堆焊和塔內構件焊接。
