Quality Steel Wire Rod SWRM22
High cost performance
Compared with medium-high carbon steel or alloy steel, SWRM22 significantly optimizes raw material costs while maintaining good processing performance, making it a wise choice for companies pursuing cost-effectiveness.
Smooth surface
Quality steel wire rod SWRM22 has good and consistent surface quality, laying a perfect foundation for subsequent surface treatments such as electroplating and painting, and reducing processing defects.
Controllable work hardening
During the cold working process, its work hardening rate is moderate and controllable. This provides a stable material response for precision forming and ensures the accuracy of the geometric dimensions of complex parts.
Low carbon
The carbon (C) content is strictly controlled at a low level, giving the material excellent plasticity, toughness and ductility. This means that during manufacturing, it can withstand drastic shape changes without cracking.
SWRM22 Wire Rod Chemical Composition
| Element | Symbol | Content range (%) | Core function |
|---|---|---|---|
| Carbon | C | 0.18 - 0.23 | Source of basic strength, low carbon ensures high plasticity |
| Manganese | Mn | 0.30 - 0.60 | Increase strength, hardenability, and improve machinability |
| Phosphorus | P | ≤ 0.030 | Strictly control, impurities, reduce cold brittleness |
| Sulfur | S | ≤ 0.035 | Strictly controlled, impurities, affecting hot brittleness |
|---|---|---|---|
| Silicon | Si | ≤ 0.10 | Deoxidizing element, trace residue |
| Copper | Cu | ≤ 0.20 (residual) | Residual elements |
Excellent performance: the cornerstone of efficient manufacturing
The chemical composition of SWRM22 steel wire rod is designed to directly translate into excellent mechanical properties suitable for cold working.
| Performance indicators | Typical value range/requirements | Significance for processing |
|---|---|---|
| Tensile strength (Rm) | 390 - 540 MPa | The basic strength index that reflects the material's ability to resist deformation |
| Cold heading performance | Excellent | Core advantage! Able to withstand high deformation rate cold heading |
| Hardness (HV) | About 110 - 150 HV | Reflects the hardness of the material, affecting mold wear and forming force |
Wide range of applications: a reliable choice everywhere
Fastener manufacturing (core application): various bolts (hexagonal bolts, carriage bolts, etc.), nuts (hexagonal nuts, flange nuts, cap nuts, etc.), screws (self-tapping screws, machine screws, wood screws, etc. - usually require heat treatment and strengthening), rivets (solid rivets), washers (flat washers, spring washers - the latter require subsequent treatment).
Hardware products and building accessories: metal stamping parts (hinges, hinge components, brackets, small hardware),
Construction nails (ordinary round nails), wire products (barbed wire, fences, wire ties, hooks), furniture hardware accessories.
Automobile and motorcycle accessories: various non-critical load-bearing structural parts, small fasteners for fixing interior parts, wiring harness fixing buckles and brackets.
Daily consumer goods: gardening tool components, internal structural parts and fixings of small household appliances, metal parts of toys.
Other general machinery: agricultural machinery accessories, standard connectors and fixings on general machinery.

SWRM22 Procurement and Application Guide
1. Clear requirements
Final product requirements: Part use, stress conditions, whether subsequent heat treatment/surface treatment is required?
Processing technology: Mainly cold heading? Cold extrusion? Cold drawing? Or a combination of processes? What is the deformation rate?
Dimensional accuracy and surface requirements: Is peeling required to obtain higher accuracy and finish?
Packaging and labeling: Are there any special requirements for coil weight, bundling method, and label information?
2. Key quality control points (before receiving and using):
Check the warranty (MTC): Confirm whether the furnace number, specifications, standards, chemical composition, mechanical properties (if any) are consistent with the order.
Appearance inspection: Check whether the surface has serious scratches, folds, scars, cracks, and whether the oxide scale is uniform or as required (such as pickling, peeling). Check whether the coils are neat and whether there are loose coils or disordered coils.
Dimension sampling: Use tools such as calipers to sample whether the wire diameter meets the tolerance requirements.
Trial processing: For large quantities or new batches, it is strongly recommended to conduct small-batch trial production to verify whether the cold forming properties (upsetting, stretching, etc.) of the material meet expectations and observe whether there are abnormalities such as cracking.
Storage recommendations: Store in a dry and ventilated warehouse to avoid rain and contact with corrosive media. Pickled or peeled materials should pay special attention to moisture and rust prevention. If necessary, apply anti-rust oil or take other anti-rust measures.
