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是金紅石涂層焊條，是所有鋼種的問題解決方案，包括不銹鋼和難焊鋼等。這種全能型焊條的典型應用包括連接硬錳鋼、工具鋼、彈簧鋼、緩沖以及連接不同等級的鋼。焊條熔敷一種抗裂焊縫金屬，鐵素體含量增加至約FN50。
