Open Die Forgings Manufacturer In China
Forged Block
Forged blocks are of higher quality than plate due to the block having forging reduction on all four to six sides if required by the application. This will produce a refined grain structure which will assure the absence of defects and material soundness. Maximum forged block dimensions depend on material grade.
Common used material: 1045 | 4130 | 4140 | 4340 | 5120 | 8620 | 42CrMo4 | 1.7225 | 34CrAlNi7 | S355J2 | 30NiCrMo12 |22NiCrMoV
FORGED BLOCK
Large press forged blocks up to 1500mm x 1500mm section with variable length.
Block forging tolerance typically -0/+3mm up to +10mm dependent on size.
All Metals has the forging capabilities to produce bars from the following alloy types:
● Alloy steel
● Carbon steel
● Stainless steel
