英國進口MWA旗艦產品工模具鈷基焊條MAC HICA E3074|ECoCrFe|獨有設計|25-50HRC|熱鍛模|沖頭|剪切工具|切邊模修復

High recovery chrome/cobalt/iron based electrode Mac Hica E3074: The MWA flagship product was developed in house, and is totally unique to MWA and our customers. This product, Mac HICA E3074, has far outperformed standard Stellite grades such as G6 & G21 for forging applications. Designed to combat all four elements of wear, i.e. heat, impact, corrosion and abrasion, but with the emphasis on impact properties. The addition of molybdenum refines the grain structure and produces good hot hardness. Excellent for rebuilding corners with minimum base metal dilution. Has ability to overlay extensive areas without cracking. Will retain hardness at high temperatures. The welds are machinable and will work harden under impact. Recommended for use in the iron and steel industries. Designed initially as a forging material for either repairs or sinking. Suitable for use on shear blades and dies, and all applications where good resistance to heat, impact, corrosion and abrasion is required. Due to its excellent impact properties and refined grain structure it is ideally suited to clipping tools and forging punches.

MWA旗艦產品高回收率鉻/鈷/鐵基焊條Mac Hica E3074，設計獨特，性能遠超標準鎢鉻鈷合金焊條(司太立焊條)，比如G6和G21。設計用于對抗所有四個磨損元素，即熱、沖擊、腐蝕和磨損，尤其是抗沖擊性能。鉬的加入細化了晶粒結構，產生了良好的熱硬度。用最小的母材稀釋度重建拐角的卓越選擇。能堆焊廣泛的區域而不開裂。在高溫下保持硬度。焊縫可加工，在沖擊下會加工硬化。推薦用于鋼鐵行業。最初設計為一種鍛造材料，用于修理或開模。適用于剪切刀片和模具等要求具有良好耐熱性、耐沖擊性、耐腐蝕性，以及耐磨性的所有應用場合。由于其卓越的抗沖擊性能和精練的晶粒結構，E3074非常適合于剪切工具、鍛造沖頭/凸模、切邊模等。
