Wheels with shot-blast hardened disks

• Wheel disk fatigue strength increased by at least 30–40% o
• Absence of fatigue cracks throughout the service life
• Wheel fatigue failure prevention, higher wheel safety and reliability for loads of up to 30 t/axle.

Wheels with 320–360 НВ rim hardness

• Wheels to GOST 10791
  • Carbon 0.55-0.65
  • НВ not less than 255 at a 30-mm depth from the tread surface
  • Homogeneous pearlitic structure
• Solid wheels to TU 0943-157-01124328-2003
  • Carbon 0.55-0.70
  • НВ not less than 320–360 at a 30-mm depth and not less than 300 at a 50-mm depth from the tread surface
  • Homogeneous, highly dispersed, pearlitic structure (without martensite or bainite)
• More than four-fold reduction in contacting and fatigue damage of wheel rims
• Service life extended at least by 1.5 times
• Reduced costs relating to machining, purchases, and repair for rolling stock

Wheels with special disk’s construction

• At least 1.8-fold reduction in radial stresses
• At least 1.6-fold reduction in stress intensity
• Improved stress pattern evenness without substantial local stress concentrations
• Wheel flange and entire wheel rim forced from the rail when circular mechanical loading is applied

Disk fatigue strength increased by at least 1.5 times

Axle load increased from 23.25 to 30 the

Wheel travel increased by more than 15% as compared with traditional wheels with 320–360 HB rim hardness

Reduced repair and operation costs
