Industrial Applications & Versatility
Originally a staple in the automotive and machine tool sectors, EN19T has evolved into
a critical material for the oil and gas industry.
Its high tensile strength makes it the ideal choice for components subjected to intense stress, including:
Drive shafts, spindles, and gears.
Heavy-duty bolts, studs, and fasteners.
Pinions and high-torque mechanical parts.
Precision Supply & Custom Specifications
We maintain a robust stock of EN19T in both round bar and sheet configurations.
Recognizing that every project has unique requirements, our facility offers precision sawing services
for one-off prototypes or high-volume production runs.
Round Bars: Available in diameters ranging from 12mm to 680mm.
EN19 QT (Quenched & Tempered): Specialized diameters stocked from 20mm to 700mm.
Steel Sheets: Available in thicknesses from 12mm to 405mm.
