Medium Chrome Tool Steel DC53 Features - Alro …

1 Alro SteelMetals Industrial Supplies PlasticsDC53 Features : Uniform distribution of fine carbides Excellent galling and wear resistance Exceptional toughness and fatigue resistance High temper resistance to support PVD and Nitride surface treatments Machining and grinding characteristics superior to most other tool steels Rounds from 1/4 diameter up to 20 diameter Flats from 1/2 to 12 thick & widths up to 24 wideMedium Chrome tool 5 7 6 The High Performance Alternative for: Punches Dies Draw & Form Dies Shear Blades Shredder Knives Thread & Form Rolls Cold Heading Dies Mill Rolls & SlittersFatigue StrengthStress Amplitude# of Cycles 1,200,000 1,000,000 800,000 600,000 400,000 200,000 0 70 75 80 85 90 95 100 Primary CarbidesPrimary Carbides in dc53 are relatively small with highly uniform distribution as compared to other tool Steel grades such as D2.

2 This helps to provide dc53 with it s superior toughness and fatigue is a general purpose cold work tool Steel with exceptional Toughness, Wear Resistance, Compressive Strength and Temper Resistance. These properties are obtained through its chemistry as well as its unique manufacturing process of ladle refinement, vacuum degassing and forging methods. dc53 also has excellent machining characteristics and is well suited as a substrate for PVD surface treatments. dc53 can also be hot process CVD and TD (Thermal Diffusion) coated, however post heat treat is generally Composition % Hardness (BHN)Specific Gravity (g/cm3)Density ( )Young s Modulus (E)Modulus of Rigidity (G)Poisson s Ratio210 - ,7008,48028DC53 (63 HRC)D2 (61 HRC) dc53 can typically be machined 20% to 40% faster than D2 while experiencing as much as 50% less tool wear and feeds and speeds reduce machining cost and yield an improved surface , , , ,600 Grinding Frequency (Time)Cut Depth (u/Time)Circum.

Given the rigors of the stainless Steel Class A surface application, a stronger material was required. We chose dc53 and have experienced an increase in tool life by a factor of three compared to traditional draw tooling. With dc53 we are able to offer our customer s a better performing Steel while decreasing our production costs, definitely a win-win situation.
