  20CrMo Alloy Structural Steel Introduction 

 20CrMo,20CrMo Steel, Alloy Structural Steel

 20CrMo Alloy Structural Steel is a kind of alloy structural steel.Its quench-hardening ability is higher, no temper brittleness.The weldability of 20CRMO steel is quite good. The tendency of cold crack formation is very small, but machinability and cold straining plasticity is good.
 20CrMo Alloy Structural Steel plate/sheet is used make all kinds of fasteners, high pressure pipe and more advanced carburized parts, such as gear, shaft, etc ,which work in the noncorrosive medium and temperature below 250 ℃, working with nitrogen hydrogen mixture in the medium.
 20CrMo Alloy Structural Steel Delivery state
 20CrMo Alloy Structural 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.
 20CrMo Alloy Structural Steel Application
 20CrMo Alloy Structural Steel plate/sheet is used for the production of various kinds of plastic molds, such as High mirror surface mold, Mold base and so on.

 20CrMo Alloy Structural Steel Packing

 20CrMo Alloy Structural 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
