HILCO HILCHROME 312R(AWS A5.4 E312-17) Rutile
Hilchrome 312R is our rutile coated electrode which is to be considered as a problem solver for all kinds of steel grades including stainless and difficult-to-weld steels. Typical applications for this WELD-ALL include joining hard manganese steels, tool steels, spring steels, buffering as well as joining dissimilar steel grades. The electrode deposits a crack-resistant weld metal with an increased ferrite content of approx. FN50. Hilchrome 312R is a core wire alloyed all-current type (AC/DC).
Hilchrome 312R是金红石涂层焊条，是所有钢种的问题解决方案，包括不锈钢和难焊钢等。这种全能型焊条的典型应用包括连接硬锰钢、工具钢、弹簧钢、缓冲以及连接不同等级的钢。焊条熔敷一种抗裂焊缝金属，铁素体含量增加至约FN50。
