Product Description
Our cast steel clamps are custom casting components specially engineered for railway/rainlroad fastening and mechanical clamping systems.
With premium cast steel alloys, optimized casting technology and strict metallographic control, our cast steel clamps are integrated cast with excellent structural rigidity, reliable mechanical stability, superior fatigue resistance and strong impact resistance, serving as core fastening parts to secure rails and matching track components steadily.
High casting precision makes our clamps perfectly fit with fastening accessories, maintaining stable and lasting clamping preload without loosening or displacement during service.
After fine-tuned surface treatment, our clamps achieve excellent anti-corrosion performance, adapting to harsh outdoor working conditions including high temperature, low temperature, rain and salt fog.

Manufacturing Process
Our Quality Control
Certified with ISO 9001 Quality Management System, we enforce stringent quality control across every production stage, covering mold design & manufacturing, wax pattern molding, tree assembly, shell mold fabrication, melting & pouring, heat treatment, machining, and final surface finishing.
Standardized inspections are carried out at all critical checkpoints to rigorously regulate casting quality, dimensional accuracy, mechanical properties, surface finish and product consistency.
We guarantee all finished products comply with customers' technical specifications, and consistently supply stable and reliable investment cast steel clamps.
Advantages of Shata's Cast Steel Clamps
- High precison
We adopt investment casting(lost wax casting), can reach Ct4-Ct6 (min ±0.13mm) for raw castings, no need machining for most of cast steel clamps, saving machining cost
- Full-process strict quality control, full QC reports provided
Chemical composition, mechanical test (tensile strength, yield strength, elongation, impact), dimensional report, hardness, surface treatment thickness...
- Superior surface finish
Our investment casting ensures the most smoothest surface- Ra6.3 for raw castings, no other casting process can be better than this
- High strength & load bearing
Tensile strength of our WCB cast steel clamps ≥570MPa; 42CrMo alloy steel clamps are even higher, ≥1080MPa, delivering doubled load capacity and superior anti-fatigue performance for ultra-heavy working conditions.
- Impact resistance & durability
WCB carbon steel has Charpy impact energy ≥35J/cm², 42CrMo reaches ≥85J/cm², effectively avoid crack formation under frequent shock loads and achieves 3x longer service durability in high-vibration heavy-load scenarios.
- High adhesion surface finishing, rust-proof, corrosion-resistant and non-peeling
Our clamp surface coating achieves adhesion grade 1 (ISO 2409 cross-cut test), salt spray resistance exceeding 500 hours, no peeling, blistering or rust penetration under long-term humid and corrosive working environments.
