                符合(相當)相關(guān)標準型號:

                GB/T 984 EDCr-A1-15

                說(shuō)明:PP-D507是低氫鈉型藥皮的高鉻閥門(mén)堆焊焊條,采用直流反接。堆焊金屬為12Cr13(1Cr13)型半鐵素體高鉻鋼。堆焊層具有空淬特性,一般不需進(jìn)行熱處理,硬度均勻。也可在750~800℃下退火軟化。當加熱至900~1000℃空冷或油淬后,可重新硬化。

                用途:適用于堆焊工作溫度在450℃以下的碳鋼或合金鋼的軸及閥門(mén)等。這是一種通用性的表面堆焊用焊條。

                注意事項:

                1、焊前焊條須經(jīng)300℃~350℃烘焙1小時(shí) 。

                2、焊前需將工件預熱至300℃以上,焊后如進(jìn)行不同熱處理可獲得相應的硬度。 

                3、焊前焊件應清除鐵銹、油污、水分等雜質(zhì)。
