高回收率铬钴铁基焊条E3074抗热冲击腐蚀磨损
High recovery chrome/cobalt/iron based electrode 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.
高回收率铬/钴/铁基焊条，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极佳选择。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。由于其极佳的抗冲击性能和精练的晶粒结构，E3074非常适合于剪切工具和锻造冲头/凸模等。
Typical All Weld Deposit Hardness
典型全焊缝熔敷金属硬度：
25-30 HRC as deposited (will work harden up to 50 HRC under impact)
25-30 HRC 熔敷状态 （在冲击下会加工硬化至50 HRC）

- Cost Effective. 成本效益佳
- Formulated Originally for UES in UK. 最初为英国UES设计。
- Easy to Use, Welder Friendly. 易于使用，对焊工要求低。
- GUARANTEED Success if Used Correctly. 如果使用正确，保证成功。
- Cobalt based electrodes tend to be hard and even worse very brittle. 钴基焊条往往很硬，甚至很脆。
- E3074 has been formulated to eliminate the brittle aspects but retain properties. E3074的配方旨在消除脆性，但保留性能。
- Chemical formulation gives a fine grained weld metal structure. 化学配方提供细粒度焊缝金属结构。
- Most Cobalt failures are by chipping/spalling? Not E3074. 大多数钴失效是由碎屑/剥落引起，但E3074不是
- Run to destruction, even after it looks to be deteriorating there is little if any downturn in performance. 即使它外观看起来正在恶化，但性能也几乎没有下滑。
