Luke Steel is a preeminent producer and distributor of S355JO+N steel sheets and plates, based in Houstan, USA. Known for quality, consistency, and reliability, we are dedicated to providing high-strength structural steel products according to international standards. Our S355JO+N plates are highly appreciated for their strength, weldability, and toughness, thereby suitable for all types of structural and industrial applications. Dedicated to timely delivery, price competitiveness, and customer satisfaction, Luke Steel supplies domestic and international markets with reliable steel products that are designed to satisfy stringent engineering requirements.
S355JO+N is a non-alloy structural steel type characterized by excellent strength and high toughness. Its composition consists of Carbon (≤0.22%), Manganese (≤1.60%), Silicon (≤0.55%), and traces of Sulphur and Phosphorus. The “+N“ signifies normalization, which improves the steel‘s mechanical properties. S355JO+N offers a minimum yield point of 355 MPa and tensile strength in the range of 470–630 MPa, with good elongation and excellent weldability. It is therefore well suited for use where load-bearing capacity and impact properties are needed, even in cold environments.
