斯米克D842鈷基焊條
名稱：堆D842鈷基合金焊條
符合：GB/T984-2001 型號：EDCoCr-D-03
相當(dāng)：AWS A5.13:2000 型號：ECoCr-B
說明：鈷基4號低碳鈷基鉻鎢合金焊芯堆焊焊條，采用直流反接，堆焊金屬在800℃仍能保持良好的抗熱疲勞性和耐蝕性。
用途：用于高溫條件下承受沖擊和冷熱交錯的工件堆焊，如熱鍛模，閥門密封面等，具有良好的性能。
堆焊層硬度：HRC28-35
許可證號:XK06-009-0124
備注：一口價為1公斤的價格！
包裝：5公斤/盒，20公斤/箱
備注：拍下備注焊條直徑3.2mm/4.0mm
品牌：飛機牌（上海名牌）
廠家：上海斯米克焊材有限公司
注意事項：
1、焊條焊前須經(jīng)150℃左右烘焙1小時。
2、宜采用小電流、短弧堆焊，以避免增加母材的熔深，降低堆焊合金的性能。
3、根據(jù)母材的種類和工件大小，可選擇350-500℃的預(yù)熱溫度和350℃的層間溫度進行堆焊。
4、根據(jù)工況條件一般選擇600-750℃，保溫1-2小時后隨爐緩冷，或?qū)⒐ぜ糜诟稍锖皖A(yù)熱的沙缸或草灰中緩冷。
