Steel
forging
Extra Forge manufactures custom closed-die steel forgings in Maribor, Slovenia, for small and medium series. We produce forgings made to your drawing with net weights up to 4 kg, including grades such as C45E, 42CrMo4 and 27MnCrB5-2.
Our programme also includes stainless steel forgings in 1.4301 and 1.4571. We review the grade, geometry, loads and delivery condition for each project. Material selection, heat treatment and any machining are agreed against your drawing.
Custom steel forgings up to 4 kg net — small and medium series
Closed-die forging shapes heated steel in a tool. Material flow, component design and subsequent processing influence the properties of the finished part. We review critical dimensions and machining allowances with your drawing; achievable tolerances and inspection requirements are confirmed for each project.
Our steel forging program focuses on
-
Mechanical engineering and industrial equipment
-
Forklift and lifting system industry
-
Agricultural machinery
-
Structures, roads and bridges
-
Lifting systems and chains
-
Transport and technical assemblies
Our quality and environmental management systems are certified to ISO 9001 and ISO 14001. For a quotation, send your drawing or 3D model, steel grade, quantities and delivery requirements. We confirm tooling, tolerances, inspection and any further processing for your project.

STEEL FORGINGS MADE TO YOUR DRAWING
C45E and 42CrMo4 – matched to the component
Our steel programme includes C45E and 42CrMo4 for components made to customer drawings. Specify the required material condition and mechanical properties. We assess geometry, forging and any heat treatment or machining as a combined production route.
27MnCrB5-2 – requirements defined by the application
For agricultural and other mechanically loaded components, material selection must reflect wear, toughness and the operating conditions. We review 27MnCrB5-2 projects against the drawing and agree the required delivery and inspection conditions.
Stainless steel forgings: 1.4301 and 1.4571
Our stainless steel programme includes 1.4301 and 1.4571. State the working environment, corrosion requirements and any welding or machining. The grade and delivery condition must suit the application; stainless steel is not automatically suitable for every medium.
From drawing review to series production
We review material, geometry and critical dimensions before agreeing tooling and the production route. Forging, trimming and any machining or surface treatment are defined for the project. Small and medium series can be assessed for both new and repeat orders.
Inspection and documentation agreed in advance
Include required material certificates, inspection records and traceability requirements in your enquiry. Our ISO 9001 and ISO 14001 certified management systems support a defined process; project-specific acceptance criteria are agreed with you before production.
Frequently asked questions about steel forging
What is needed for a quotation?
Send your drawing, steel grade, quantities and required delivery date.
Does ±0.2 mm apply to every steel forging?
No. We confirm tolerances and machining requirements against your drawing.
