斯米克D802鈷基焊條 鈷基1號堆焊焊條
名稱：Stellite6 D802鈷基1堆焊焊條
符合：GB/T984-2001 型號：EDCoCr-A-03
相當：AWS A5.13:2000 型號：ECoCr-A
說明：D802是鈦鈣型藥皮，連鑄鑄造的Stellite 6合金焊絲為焊芯的堆焊焊條?？山恢绷鲀捎?，宜采用直流反接，焊條接正接。電弧穩(wěn)定，渣覆蓋性好，成型美觀。堆焊層在800℃以下高溫范圍具有優(yōu)良的綜合機械性能,并有良好的耐腐蝕,抗氧化和抗金屬間沾著磨損性能。堆焊層可進行機加工。
用途：用于要求高溫耐磨和耐腐蝕的場合,如高溫高壓閥門、氣門、熱剪刀刃、熱鍛模等。
堆焊層硬度：HRC35-45
許可證號:XK06-009-00060
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。
