Steel Grade
- 10: Low carbon steel, used for general mechanical parts
- 20: Medium carbon steel, better strength and toughness than 10
- 35: Medium carbon steel suitable for parts with higher strength requirements
- 45: High carbon steel grade for components requiring high strength and wear resistance
- 10G2: A variant with controlled addition of elements like Cu, Ni, Cr to improve corrosion resistance and mechanical properties
Application
- Machine construction parts such as shafts, bushings, and sleeves
- Automotive components
- Hydraulic cylinders and pneumatic equipment
- Precision mechanical tools and instruments
- Pipes and tubes for instrumentation and transport of fluids under pressure
- Structural parts requiring seamless and precise steel pipe
