[Technical Specification]
DIN Standard | SAE-4145 (42CrMo4) |
Other Grade | Werkstoff Nr. 1.7220 - SAE/AISI 4145 |
Steel Type: | Alloyed Steel |
Material Allowance | Dimensions (mm): OD +5/-0, ID ±1,0, Length +10/-0 |
Heat Treatment | Normalized |
Hardness | 210 - 240 HB |
Granulometry | (ASTM E112): 5 - 8 ASTM austenitic |
Cylindricity | According DIN 7184 = 3,0 mm |
Surface Finished | Machined (rough turned with material allowance) |
Tolerances | ±10% is allowed |
[Technical Requirement]
Steel specification: according to NIF CR-016 (Technical Specification of Supply for forged bar and tubes)
Peripheral Holes: according to NIF CR-028 (Technical Specification of Supply for peripheral bores)
Dimensions and tolerances: according to the drawings
[Documentation & Material Requirements]
1. Chemical Analysis Certificate (of each charge); 2. Ultrasonic Test Certificate ASTM A-388/80
3. Mechanical Properties Certificate; 4. Hardness Test Certificate (of each forged part)
5. Charge identification (order and item) in each forged part;
6. Grain Size Certificate (of each charge);
7. Inspection Protocol (peripheral holes for each forged tube);
Peripheral Hole Dimensional Protocol
Inspection of drilling deviations must be done by ultrasound along the length of the holes. Points A and B must be registered, where the holes are spliced, as the drilling process is done in two stages, from the face to the center of the bar.
Range of application: These forged tubes are used for making the roller on the corrugated machine..
