https://youtu.be/Trb5mPhOxJQ International Standard (ISO 630) Fe 360B (GR 235) Yield Strength: 235 MPa Tensile Strength: 360–510 MPa Equivalent Note: Mechanical performance aligns with Q235B. Chemical Composition: Q235B has a slightly higher carbon content (≤0.20%) compared to S235JR (≤0.17%), but shares similar sulfur and phosphorus content levels. Application Scenarios: S235JR (EN
https://youtu.be/woFdO8j1tzs HRB400E is a hot-rolled ribbed steel bar defined in the Chinese standard GB/T 1499.2, characterized by a yield strength of 400 MPa and enhanced seismic performance (Grade E). Key Details: Standard: GB/T 1499.2 (China). Type: Hot-rolled ribbed/deformed steel bar. Yield Strength: 400 MPa (minimum). Seismic Grade: “E” designation ensures
Q235B Steel Plate Chemical Composition (by mass percentage) Element Content Range (%) Standard Requirement (Max.) Notes Carbon (C) ≤0.20 ≤0.22 Affects strength and weldability Silicon (Si) ≤0.35 ≤0.35 Acts as deoxidizer, enhances strength Manganese (Mn) 0.35-0.80 ≤0.80 Improves toughness and workability Sulfur (S) ≤0.045 ≤0.045 Harmful element, causes hot brittleness

Although the country is highly dependent on imported iron ore, it has established a relatively stable raw material procurement
The common calculation formula for Chinese rebar is: weight (kilograms) = diameter (millimeters) × diameter (millimeters) × 0.00617 × length (meters). For example, to calculate the weight of rebar with a diameter of 20 millimeters and a length of 12 meters: First calculate the weight per meter according to
The quality standards of Chinese deformed steel bars in China mainly follow GB1499.2 – 2024 “Steel for the Reinforcement of Concrete – Part 2: Hot – Rolled Ribbed Bars”. The main quality standards include the following aspects: Chemical Composition The main elements include carbon (C), silicon (Si), manganese (Mn),
https://www.facebook.com/reel/3158671220939186 Advantages in Raw Material Costs: Strong Self-sufficiency in Coking Coal: China is relatively rich in coking coal resources, with a high domestic self-sufficiency rate of about 90% for coking coal. This gives Chinese steel enterprises a cost advantage in coking coal procurement, as it reduces the transportation costs
