4140 PH or 4140 PREHARD has the same industry standard chemistry as above.
4140 Steel Bar 4140 HR Plate
Oil Quenched & Tempered 4140 PH has a standard, industry recognized Rockwell C Hardness rating of 28 - 32.
Most sources recognize and tend to prefer quoting and requesting the Rockwell C Scale. 4140PH ranges from Brinell Hardness 270 - 300.
Thick 4140 AN (in the Annealed condition) is flame cut, then Annealed onsite in our furnace. Annealing greatly improves Grinding and Machining. Parts can be returned to the standard hardness when followed by a Normalize & Specific Tempering heat treatment process.
Typical Applications:
Tooling, machine plates, gears, shafts, sprockets, Special Machine Parts
Molds, Metal Stamping, Tool & Die, Shredders
Automotive, Oil & Gas Industries, Machine Shop, Paper Mills
