CS Heavy Forgings supplies custom EN19 forged shafts and crankshafts for gearboxes, presses, rolling mills, power-transmission systems and other highly loaded machinery.
EN19 is an engineering alloy-steel designation commonly requested for components requiring strength, toughness and fatigue resistance after appropriate heat treatment. Buyers should state the complete standard, required condition and mechanical properties because grade equivalence and achievable properties depend on the specification and section size.
Review the broader steel grades for heavy forgings guide before comparing material families. Final selection remains the responsibility of the purchaser or component designer and must follow the complete drawing and specification.
Target applications
- Heavy-duty transmission shafts
- Industrial cranks and crankshafts
- Gearbox and press components

Frequently asked questions
Why is EN19 considered for heavy-duty shafts?
EN19 is specified for many engineering components where the design requires a combination of strength and toughness after controlled heat treatment. Suitability must be confirmed from the buyer drawing and standard.
What details are needed for an EN19 crankshaft quotation?
Provide the drawing, material standard, finished and forging dimensions, heat treatment, mechanical properties, machining scope, testing, quantity and delivery requirements.
