Manufacturing Process and Material Selection for Heavy-Duty Steel Chains

As a professional supplier and wholesaler of heavy-duty steel chains, Shanghai TCH Metals & Machinery Co., Ltd. understands that the manufacturing process and material selection are crucial to product quality and performance. We are committed to providing customers with high-quality, durable steel chain products, which is a result of our advanced manufacturing technology and strict control over high-quality raw materials.

Materials Selection: Laying a Solid and Durable Foundation

The load-bearing capacity and wear resistance of heavy-duty steel chains primarily depend on the steel material chosen. The steel we select at our company must possess the following key characteristics:

• High Strength: To withstand immense tensile and impact forces, we use high-carbon alloy steel or special alloy steel. After special treatment, these materials can significantly increase the chain's load-bearing limit, preventing deformation or fracture during use.
• High Wear Resistance: Over long-term use, friction will occur at the chain joints. The steel we select has excellent wear resistance, which effectively resists abrasion and extends the product life.
• Corrosion Resistance: For special working environments such as high humidity or chemical corrosion, we use materials with surface treatments (like galvanizing or special coatings) to enhance the chain's anti-corrosion ability, ensuring its reliable performance in harsh conditions.

Manufacturing Process: A Pursuit of Excellence

At Shanghai TCH Metals & Machinery Co., Ltd., the manufacturing process for heavy-duty steel chains is a systematic and meticulous process. Our modern facility is equipped with the latest machinery, ensuring every step meets the highest standards:

1. Raw Material Preparation and Cutting

We source steel from high-quality suppliers and use precision machinery for cutting and shaping. This step ensures that the dimensions and shape of each chain link are accurate and precise.

2. Forging and Forming

This is one of the most critical steps in the manufacturing process. We use advanced forging technology to treat and shape the steel at high temperatures, making the chain link structure denser. This significantly increases its mechanical strength and anti-fatigue performance.

3. Heat Treatment

Heat treatment is the core process that gives the steel chain its superior performance. Through processes like quenching and tempering, we can precisely control the chain's hardness and toughness, making it resistant to brittleness while maintaining high strength. This is a key technological advantage that sets our products apart from ordinary steel chains.

4. Welding

We use high-precision welding equipment to securely connect the chain links. The strength of the weld points is directly related to the safety performance of the entire chain. We ensure that every weld point is free of defects and pores, meeting or exceeding international safety standards.

5. Surface Treatment

After the main manufacturing process is complete, we perform surface treatments like polishing, galvanizing, or coating based on customer needs to enhance the chain's appearance and corrosion resistance.

6. Quality Inspection

Before leaving the factory, every batch undergoes a strict quality inspection. This includes tensile testing, hardness testing, dimensional accuracy checks, and visual inspections. We ensure that every steel chain delivered to our customers meets or exceeds international safety standards, providing reliable assurance for their business.

It is through our unwavering dedication to excellent materials and strict control over advanced processes that Shanghai TCH Metals & Machinery Co., Ltd. has become a leading company in the heavy-duty steel chain industry, earning the trust of customers across various sectors.
