1.Why is steel cheap in China?
The historically low price of steel in China is primarily a consequence of **severe overcapacity** . For a long time, China's steel industry has produced far more than domestic demand requires. This oversupply in the market naturally drives prices down.
Several factors contribute to this overcapacity:
* **Policy-Driven Production**: In the past, local government evaluations heavily prioritized GDP growth. Since steel production contributes significantly to economic output figures, local governments had an incentive to keep steel plants operating, even at a loss, to "preserve" GDP and employment, leading to inefficient and continuous expansion .
* **Uneven Industrial Structure**: The market has been characterized by an excess of low-end steel products and a shortage of high-end, specialty steels. Some smaller steel mills with lower environmental and labor costs (around 30 yuan/ton) could undercut larger, compliant enterprises (with costs of 120-150 yuan/ton), creating a race to the bottom on price .
* **Export Pressure**: To manage high domestic inventory, Chinese steel companies have often turned to exports, sometimes leading to trade friction as other countries allege the steel is sold at unfairly low prices .
2. What is the price of A36 steel per kg?
A specific recent price for A36 steel is not available in the search results. However, a reference from early 2025 lists a price of **3,750 Yuan per ton** for ASTM A36 steel plate .
To convert this to a per-kilogram price:
* **3,750 Yuan/ton ÷ 1,000 kg/ton = 3.75 Yuan/kg**
Please be aware that this is a single data point and the actual price can vary significantly based on factors like order quantity, form (plate, bar, etc.), region, and current market conditions. For a precise quote, it is best to contact suppliers directly.
3.Is A36 steel strong?
Yes, A36 steel is considered a strong material for general structural applications. Its strength is defined by its mechanical properties :
* **Yield Strength**: Minimum of **250 MPa (36,000 psi)**. This is the stress at which the steel begins to deform permanently, and it is the key property behind the "36" in its name.
* **Tensile Strength**: Ranges from **400 to 550 MPa (58,000 to 80,000 psi)**. This is the maximum stress the steel can withstand while being stretched or pulled before breaking.
It offers a good balance of strength, ductility (it can elongate by 20% or more before fracturing), and ease of fabrication, making it a versatile choice for construction and manufacturing .
4. Which steel is cheaper?
The question "which steel is cheaper" depends entirely on the specific grades being compared. Generally, within the same category (e.g., carbon steel), the price is influenced by chemical composition and processing.
A common comparison can be made between **A36** and **SAE 1018**:
* **A36** is a **"property standard"** steel. Its classification is based on achieving minimum mechanical properties (like yield strength), with more flexibility in its chemical composition .
* **SAE 1018** is a **"chemical composition"** steel. Its classification is based on a specific, controlled chemical content (e.g., carbon around 0.18%) .
5. Is A36 cheaper than 1018?
Yes, typically **A36 is cheaper than 1018** . The main reason is the difference in production control. Because A36 must meet mechanical property targets but has more flexibility in its chemical makeup, producers can use a wider range of raw materials and less stringent processes to achieve the required strength, which helps lower the production cost. SAE 1018, with its strict chemical requirements, often involves more controlled and costly production methods, resulting in a higher price.
