PRODUCT INTRODUCTION

15CrMo carbon steel bar is a low-alloy heat-resistant steel commonly used in manufacturing high-temperature and high-pressure components. With a chromium (Cr) and molybdenum (Mo) alloying composition, this material offers superior strength, thermal stability, and corrosion resistance under extreme working environments.

Our 15CrMo steel bars are available in various sizes and lengths, precisely machined and tested to meet GB/T 3077 and ASTM/AISI standards. With uniform microstructure and smooth surface finish, they ensure stable performance in welded and forged conditions.


PRODUCT Features:

  • Grade: 15CrMo (GB/T 3077 standard)

  • Process: Hot rolled / forged / peeled / heat treated

  • Size: Diameter 20mm – 300mm or custom

  • Condition: Annealed / normalized / tempered

  • Surface: Black, bright, or machined finish

  • MOQ: 1 ton | Custom sizes available

  • Certification: ISO 9001, EN10204 3.1 available

APPLICATION

15CrMo steel bars are widely used in industries requiring excellent mechanical strength and high-temperature performance. This includes:

  • Power plants – used for manufacturing high-pressure boiler tubes and steam pipes

  • Petrochemical industry – applied in reactors, heat exchangers, and pressure vessels

  • Mechanical engineering – for shafts, fasteners, and high-load components

  • Oil & gas – critical structural parts in refineries and drilling equipment

Its ability to withstand long-term operation at temperatures up to 580°C makes 15CrMo an optimal material for thermal power and chemical process applications.
