Product Description

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.

Product Show

Crafted from premium austenitic, martensitic, and duplex grades (304, 316, 410, 2205, etc.), our stainless steel bars deliver exceptional corrosion resistance, high strength, and precise machining performance. Available in round, square, hexagonal, and flat shapes with hot-rolled or cold-finished surfaces, these bars comply with ASTM A276, A479, and international standards. Ideal for machining parts, automotive components, construction hardware, and industrial tools. Custom sizes and grades supported.


Manufactured using precision hot rolling and cold drawing processes, our stainless steel bars undergo controlled annealing and straightening to ensure uniform mechanical properties and dimensional stability. Equipped with laser micrometers (±0.05mm tolerance) and ultrasonic testing for defect detection, we guarantee consistent quality in round, square, hexagonal, and flat shapes. Compliant with ASTM A276/A479 and international standards. Custom sizes and material grades (304, 316, 410, 2205, etc.) are supported.


In order to ensure product quality, we will arrange professional personnel to check product quality, packaging, weight, hardness, etc., according to customer requirements of product specifications, looking for high-quality and cheap cooperative factories in China, to provide customers with one-stop procurement services and quality assurance.


Excellent packaging: waterproof paper and plastic film + iron cover + at least three strapping straps + strapping straps fixed on iron or wood pallets can effectively protect products from corrosion and various climate changes during transportation. Generally speaking, we ship from Shanghai, Tianjin, Qingdao and Ningbo ports. We have worked with many experienced shipping companies for a long time to find the most suitable mode of transportation for you.
