Product Description

不锈钢 拷贝


We supply 405 stainless steel bars, a ferritic stainless steel containing added aluminum to suppress martensite formation during welding. This grade offers good oxidation resistance, moderate corrosion performance, and excellent weldability without post-weld heat treatment, making it suitable for thermal cycling applications and welded assemblies exposed to mildly corrosive environments.

Core Features

  • Excellent Weldability: Aluminum content minimizes hard martensitic zones in weld areas, reducing cracking risk.

  • Thermal Stability: Resists oxidation and scaling at temperatures up to 815°C (1500°F), suitable for heat-exposed parts.

  • Moderate Corrosion Resistance: Performs well in atmospheric, steam, and mild chemical conditions.

  • Magnetic Properties: Exhibits ferritic magnetism, useful in applications requiring magnetic permeability.

Applications
Ideal for welding fixtures, heat exchanger components, boiler parts, furnace hardware, and structural assemblies in moderate-temperature corrosive environments.

We provide bars in rounds, squares, and hexagons, with options for cutting, heat treatment, grinding, and surface finishing. Full material certification compliant with ASTM A276, EN 10088-3, JIS G4303, and related standards is included.
