High Carbon Steel Wire Rod swrh82a
High strength and hardness
High carbon content gives it excellent strength and wear resistance, providing reliable support for the final product.
Cold processing
Wire rod swrh82a is particularly suitable for cold heading, cold extrusion, cold drawing and other processes, with high forming efficiency.
Fatigue strength and elasticity
After proper heat treatment, it can obtain excellent elasticity and fatigue resistance, and is the first choice for spring parts.
Quality and size
Strictly control the production process to ensure the smooth surface of the wire and accurate dimensional tolerances, reducing subsequent processing problems.
SWRH82A Key chemical composition (JIS G 3506 standard typical range)
| Element | Content range (%) | Core function |
|---|---|---|
| Carbon (C) | 0.79 - 0.86 | Core strengthening element, providing high strength and hardness |
| Silicon (Si) | 0.15 - 0.35 | Deoxidation, improving strength and elasticity |
| Manganese (Mn) | 0.30 - 0.60 | Improving hardenability, strength and wear resistance |
| Phosphorus (P) | ≤ 0.030 | Harmful elements, strictly controlled (the lower the better) |
|---|---|---|
| Sulfur (S) | ≤ 0.030 | Harmful elements, affecting hot brittleness (the lower the better) |
SWRH82A Typical Mechanical Properties
| Performance indicators | Typical value range/state description |
|---|---|
| Tensile strength (Rm) | ≈ 1080 MPa or higher (depending on size and state) |
| Reduction of area (Z) | ≥ 30% (good ductility) |
| Hardness (HV) | ≈ 320 - 380 HV (rolled/annealed reference) |
Application of SWRH82A wire rod
With its excellent performance, SWRH82A steel wire shines in many key areas:
1. High-end spring manufacturing -- High Carbon Steel Wire Rod In Coil
Various types of coil springs: clutch springs, valve springs (valve springs), suspension springs.
High-stress spring sheets: Applications that require extremely high fatigue life and anti-relaxation performance.
Precision springs: Small high-precision springs in instruments and electronic equipment.
2. High-strength fasteners -- High Carbon Steel Wire
High-grade bolts, screws, nuts: Such as automobile engine bolts, chassis connectors, key bolts for engineering machinery (often requiring 8.8, 10.9, 12.9).
Special-shaped fasteners: Parts with complex shapes formed by cold heading.
3. Key automotive parts -- High Carbon Steel Wire Rod
Transmission parts (such as shift forks and bushings).
Engine peripheral parts.
Chassis system parts.
Safety system parts (such as seat belt retractor core parts).
4.Machinery manufacturing and tools -- Quality Steel Wire Rod
Pin shafts, washers, chain links.
Core parts of hand tools (such as pliers and wrenches).
Wear-resistant parts of agricultural machinery.
Why choose SWRH82A steel wire rod from us?
1. Direct supply from the source, excellent quality
We have established long-term strategic cooperation with many large-scale high-quality steel mills to ensure that each batch of SWRH82A wire meets JIS G 3506 and customer-specific standard requirements, with stable composition and consistent performance.
2. Strict quality control system
Incoming inspection: Each batch undergoes strict chemical composition spectral analysis (to ensure that core elements such as C, Si, Mn, P, S meet the standards).
Surface and size control: All or a high proportion of wire surface defects (cracks, folds, scars, pitting, etc.) are checked, and the diameter tolerance (usually up to ±0.1mm or even higher accuracy) and out-of-roundness are strictly controlled.
3. Flexible and diverse specifications and inventory
Wide diameter range: Conventional supply of Φ5.5mm - Φ20mm wire, special specifications can be customized (Φ22mm and above need to be confirmed).
Diversified packaging: Standard I-shaped wheels (1-2 tons/reel), bundled packaging, to meet different transportation and production line requirements.
