英国进口MWA旗舰产品工模具钴基焊条MAC HICA E3074|ECoCrFe|独有设计|25-50HRC|热锻模|冲头|剪切工具|切边模修复

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旗舰产品高回收率铬/钴/铁基焊条Mac Hica E3074，设计独特，性能远超标准钨铬钴合金焊条(司太立焊条)，比如G6和G21。设计用于对抗所有四个磨损元素，即热、冲击、腐蚀和磨损，尤其是抗冲击性能。钼的加入细化了晶粒结构，产生了良好的热硬度。用最小的母材稀释度重建拐角的卓越选择。能堆焊广泛的区域而不开裂。在高温下保持硬度。焊缝可加工，在冲击下会加工硬化。推荐用于钢铁行业。最初设计为一种锻造材料，用于修理或开模。适用于剪切刀片和模具等要求具有良好耐热性、耐冲击性、耐腐蚀性，以及耐磨性的所有应用场合。由于其卓越的抗冲击性能和精练的晶粒结构，E3074非常适合于剪切工具、锻造冲头/凸模、切边模等。
