Buy High Tensile Steel Online
Custom-cut to Order Delivery or Click & Collect
At Edcon Steel, our high tensile engineering steel range is suited to both trade professionals and capable DIY users. We stock high tensile steel in practical forms including round bar, flat bar, plate, and rod, commonly used for shafts, pins, bolts, brackets, and high-stress components. These steels are valued for their resistance to wear, impact, and fatigue, making them a trusted choice across construction, fabrication, mining, and mechanical projects.
High tensile steel is an alloy steel engineered for superior strength, toughness, and load-bearing performance. Compared to standard mild steel, it delivers significantly higher tensile strength, making it ideal for demanding structural, mechanical, and engineering applications where reliability is critical. High tensile steels are commonly alloyed with elements such as chromium and molybdenum and supplied in a heat-treated condition to achieve an excellent balance of strength, hardness, and machinability.

Cut to Size. Packed. Delivered.
- We can custom cut lengths to the millimetre – minimum cut just 15 mm.
- Cut-to-size items are often available in-store while you wait, and online orders are processed the same day or the next day in most cases.
- Shorter cuts are cheaper to ship and sent via couriers or Australia Post.
- Large or long orders are delivered by our own delivery truck fleet in NSW or by national freight partners.
Work Smarter with Edcon Steel
Cut with the Right Tools: High tensile steel is harder than mild steel. Use quality blades and drill bits, or order cut-to-size from Edcon Steel to save time and tool wear.
Bend with Care: These steels are less forgiving when bending. Avoid tight bends and consider professional advice for heated or formed applications.
Protect Against Corrosion : High tensile steel is not corrosion resistant. Apply paint, oil, or protective coatings for outdoor or damp environments.
Handle and Store Safely: Bars can be heavy and sharp once cut. Use proper lifting methods and store steel off the ground in a dry area.
Check with a Professional: Our advice is general in nature. Always confirm your specific steel sizes, load-bearing requirements and compliance needs with a qualified engineer or builder.
Common Uses and Sectors: High Tensile Steel
High tensile engineering steel is widely used in applications where strength, durability, and reliability are essential. In the building and construction sector, it is commonly specified for load-bearing components such as threaded rods, pins, brackets, and structural fixings where standard mild steel is not sufficient. Civil and infrastructure projects rely on high tensile steel for engineered parts exposed to heavy loads, vibration, and long-term wear.
Across manufacturing, mechanical, and fabrication industries, high tensile steel is machined into shafts, axles, gears, bolts, and wear-resistant components used in plant equipment, vehicles, and machinery. It is also widely used in mining, agriculture, and transport, where parts must perform under high stress and harsh working conditions.
Edcon Steel supplies high tensile steel to customers across Sydney and regional NSW, including Brookvale, Revesby, Blacktown, Orange, and Bathurst. With custom cutting and Australia-wide delivery available, our high tensile steel supports projects of all sizes, from workshop fabrication to large-scale industrial and infrastructure builds nationwide.

Yes. Free Click & Collect is available from Brookvale, Revesby, Blacktown, Bathurst, and Orange . We’ll notify you when your order is ready.
What forms of high tensile steel do you stock?
Our range includes round bar, flat bar, plate, and rod, with availability depending on size and grade.
Is high tensile steel suitable for welding?
High tensile steel can be welded, but correct procedures are required. Pre-heating and controlled cooling are recommended for best results.
Is high tensile steel corrosion resistant?
No. High tensile steel is not stainless and should be painted, oiled, or coated if used outdoors or in damp environments.
How do I choose the right high tensile steel grade?
4140 is suitable for most applications. For higher loads or specialised uses, our team can help you select the most appropriate grade for your project.
