Product Description
High Carbon Spring Tempering Steel Wire Description
Mainly Divided Into Three Categories:
Hard pull spring steel wire: Also known as HDMB spring wire, it is a cost-effective choice for many general-purpose applications. The carbon content ranges from 0.45 to 0.85 percent. Since it is usually not heat-treated after drawing, it has high strength and medium toughness. It is available in a variety of diameters and is manufactured in accordance with ASTM A227 (uncoated finish) and ASTM A764 (galvanized finish).
Oil tempered spring steel wire: Also known as OTMB spring steel wire, it is an excellent general-purpose spring steel wire with improved performance compared to hard drawing. The carbon content ranges from 0.55 to 0.85 percent. After drawing, the oil-tempered wire rod is subjected to heat treatment and controlled cooling in an oil bath to increase its toughness while maintaining high tensile strength. This makes it particularly suitable for applications requiring high impact resistance or a large number of deflection cycles. Oil tempered spring steel wire is available in a variety of diameters and is manufactured in accordance with ASTM A229. This grade does not provide a galvanized finish.
Music spring high quality steel wire: Also known as music wire or piano wire, it is a very high quality steel wire suitable for demanding applications. The carbon content ranges from 0.70 to 1.00 percent. The music wire is heat treated after drawing to relieve stress and toughen the wire while maintaining high tensile strength. The strings are typically 0.250 inches or less in diameter and are manufactured in accordance with ASTM A228. It has a variety of surface treatments to choose from, such as bright, phosphate, tin and zinc.
Scope of Application
High Carbon Spring Tempering Steel Wire known for high strength and hardness, often used in manufacturing high-strength wires for industrial purposes, springs, and specialty applications like piano wires.

FAQ
1. What are your main products?
We primarily deal in carbon steel (hot-rolled/cold-rolled sheets, coils, pipes, and bars), structural steel (angle bars, channel steel, I-beams, H-beams, square/rectangular tubes, etc.), galvanized products (galvanized sheets, coils, pipes, and profiles), and aluminum products (sheets, coils, profiles, and bars). We can also supply other steel varieties based on customer requirements.
2. Are you a manufacturer or a trader?
We are a comprehensive service provider integrating trading, processing, and distribution. We maintain close partnerships with major steel mills in Vietnam and the surrounding region, ensuring a stable supply chain. Additionally, our in-house processing center offers value-added services, combining the flexibility of a trader with the service capabilities of a processing plant.
3. Do you accept small-batch orders? What is the minimum order quantity (MOQ)?
Yes, we support small-batch and trial orders. The MOQ is typically one container (approx. 20–25 tons), depending on product specifications and dimensions. MOQs for aluminum products can be lower; please contact us for details.
4. What is the typical delivery time?
For standard products, delivery takes 15–30 days after receipt of the deposit, depending on order volume, product type, and current production scheduling. Stock items can be delivered sooner. Delivery times for customized orders will be longer, and we will inform you in advance.
5. What payment methods do you accept?
We generally accept T/T (Telegraphic Transfer) and L/C (Letter of Credit). More flexible payment terms can be negotiated for long-term clients. Specific ratios (e.g., 30% down payment and 70% balance) can be adjusted based on the order value and credit status.
6. What processing services do you offer?
We provide services such as cutting, punching, bending, welding, uncoiling, and leveling. We also offer customized deep processing of profiles based on technical drawings. All processing is performed in-house to ensure quality control and timely delivery.
