High-Strength Steels – Lighter, Stronger, Tougher
We supply structural and alloy steels with high tensile strength, impact resistance and weldability. Ideal for demanding industries such as construction, transportation, mining and machinery.
What Is High-Strength Steel?
High-strength steel (HSS) refers to steels engineered to provide superior yield strength, tensile strength, and impact resistance while allowing for weight reduction and structural efficiency.
It includes:
Structural high-strength steel: Q460, Q690, S690QL, S960QL
Alloy tool steels: 42CrMo4, 5140, 8620, 34CrNiMo6
Tempered & quenched steels: for wear and dynamic loading
Advantages:
High strength-to-weight ratio
Excellent formability and weldability
Fatigue resistance under cyclic load
Toughness at low and high temperatures

Frequently Asked Questions
Q1: What’s the difference between Q690D and S690QL?
A:
Q690D is a Chinese standard high-strength low-alloy steel, while S690QL is a European EN10025-6 quenched and tempered grade. Both offer ~690MPa yield strength.
Q2: Do you supply tempered bars like 42CrMo4 Q+T?
A:
Yes. We stock and process quenched and tempered bars up to 600mm diameter.
Q3: Can high strength steel be welded?
A:
Yes, but proper preheat, filler selection and post-weld treatment are required. We provide WPS and guidance.
Q4: Do you provide MTC and impact testing?
A:
Absolutely. MTC with yield/tensile/impact values are provided with every batch.
Q5: Do you accept custom-cut or small lot orders?
A:
Yes. Cut-to-size and MOQ flexibility available especially for project sourcing.
