Materials, Treatment & Quality Control
Material options: 50M (carbon-manganese / specified grade) or U71Mn (high-manganese wear-resistant rail steel), selectable per service condition.
Heat & surface treatments: Head-hardening (HH), surface hardening or standard rolled supply; surface protection options include hot-dip galvanizing, primer/paint or corrosion-preventive oil.
Certificates & inspection: Shipments accompanied by MTC (chemical analysis, tensile/yield, head hardness, Charpy where applicable). Third-party inspection (SGS/BV/etc.) and NDT (UT/MT/ET) can be arranged. Sampling frequency and acceptance criteria should be defined in the contract for critical applications.
Welding & installation: Compatible with aluminothermic (thermit) and flash-butt welding; mechanical splice bars (fishplates) for removable joints. Welding procedure specifications and installation guidance provided.
Typical Applications
Plant internal transfer tracks and workshop rails
Light branchlines and short industrial transfer routes
Temporary/portable track panels and underground auxiliary lines
FAQs
