NAXTRA 70 is a robust, quenched-and-tempered structural steel grade crafted for tough, heavy-duty applications. These plates are designed to offer an outstanding mix of strength, toughness, weldability, and performance under load. With impressive mechanical properties and dependable fabrication characteristics, NAXTRA 70 sheets and plates find their place in structural engineering, heavy machinery, and manufacturing industries where durability and strength are paramount. ([yousefsteel.com][1])
The typical chemical makeup of NAXTRA 70 features carbon (~0.20%), silicon (~0.80%), and manganese (~1.70%), along with alloying elements like chromium (~1.50%), copper (~0.50%), molybdenum (~0.70%), nickel (up to ~2.0%), and micro-alloying elements (such as boron, niobium, titanium, and vanadium) to boost strength and toughness. Phosphorus and sulfur levels are kept low (~0.025% and ~0.015% respectively) to ensure excellent weldability and structural integrity. ([yousefsteel.com][1]) Mechanically, NAXTRA 70 plates typically deliver a **yield strength of ~690 MPa**, with tensile strength and elongation properties that cater to heavy-duty applications.
