 40Cr Steel Introduction 

40Cr,40Cr Steel, Alloy Structural Steel

40Cr is Mainly used to make various alloy structural parts and components, such as station boiler superheater collector, large-diameter pipe plate structure, various shaft, gear, gear rod.. After quenching with good mechanical properties,40Cr has good low temperature impact toughness and low notch sensitivity. Good hardenability of steel, water-quenching hardenability to Ф28 ~ 60mm, when oil quenching hardenability to Ф15 ~ 40mm. 40Cr steel is quenched things, except for cyanide and high frequency quenching. Cutting preferably, when the hardness of HB174 ~ 229, the relative machinability of 60%. The steel is suitable for production of medium-sized plastic molds.
40Cr Steel Delivery state
40Cr Steel Material should be delivered at hot-rolled or hot wrought conditions. Once the demander requires(and stipulates in the contract),hot processing condition(annealing, normalizing or high-temperature backfire) can also be adopted.
40Cr Steel Application
40Cr is Mainly used to make various alloy structural parts and components, such as station boiler superheater collector, large-diameter pipe plate structure, various shaft, gear, gear rod.

40Cr Steel Packing

40Cr Steel Packing is normally wrapped by plastic film and waterproof paper, and then fastened on wooden pallet or as you request.

Stainless Steel Surface Finishes:

1. No 1 Finish : Used where Heat and corrsoion ressistance is required . Produced by annealing and resealing after hot rolling .

2. No 2D Finish : Dull Cold rolled finish . Used in deep drawn objects which are often polished after fabrication

3. NO 2 B Finish : Bright Cold Rolled Finish . Used in very deep drawn objects .

4. No 3 Finish : Polished finish obtained with abrasives

5. No 4 Finish : Used for kitchen ware , cooking utensils , restaurants and hotel kitchenware , cookware . Obtained with abrasives of 125 mesh and higher

6. NO 7 Finish : Architectural and Ornamental Finish

7. NO 8 Finish : Press plates , small mirrors and reflectors

8. Hairline finish : Ornamental plates , decorative items , name plates , elevators , doors in buildings
