Hardness Comparison Table-Drop Forging-Investment Casting-Steel Casting Hardness Test Process and Table

We could use the Normalizing, Tempering, Annealing to reach the hardness our customer required. I attached the hardness comparison Table for customers to check the hardness. 

Our main products are investment casting, lost wax casting, forging, large forging, mold forging, machining, steel casting, aluminum casting, etc. 

All our parts could be OK to reach the hardness required!
