- Description
Stainless steel round bar is widely used in machining, construction, pièces automobiles, attaches, et fabrication d'équipements industriels. One of the most important selection factors is material grade, because different stainless steel grades determine corrosion resistance, force, usinabilité, and application range. Common stainless steel round bar grades mainly come from austenitic, ferritique, martensitique, and duplex families.
Nuances d'acier inoxydable austénitique
Austenitic grades are the most widely used stainless steel materials for round bars due to their excellent corrosion resistance and good formability.
- 304 / 304L: general-purpose grade, widely used in machinery and construction
- 316 / 316L: improved corrosion resistance, especially for marine and chemical environments
- 303: free-machining grade with added sulfur for better machining performance
- 321: titanium-stabilized grade for high-temperature applications
- 310 / 310S: high-temperature resistant grade for furnace and heat treatment parts
Nuances d'acier inoxydable ferritique
- 430: commonly used ferritic grade with good corrosion resistance in mild environments
- 439: improved weldability and corrosion resistance compared to 430
- 409: widely used in automotive exhaust systems
- 444: enhanced corrosion resistance with molybdenum addition
Nuances d'acier inoxydable martensitique
Martensitic stainless steels are known for high strength and hardness after heat treatment, making them suitable for wear-resistant and structural applications.
- 410: basic martensitic grade with good hardness
- 420: higher carbon content for improved wear resistance
- 431: improved corrosion resistance and toughness
Nuances d'acier inoxydable duplex
- 2205: most common duplex grade with high strength and corrosion resistance
- 2507 (Super-Duplex): extremely high resistance to chloride corrosion and pitting
Why These Grades Are Common for Round Bar
- Wide availability from global mills
- Balanced mechanical properties for machining and structure
- Different corrosion resistance levels for different environments
- Convient pour couper, tournant, and CNC machining
Applications typiques
- Mechanical shafts and rotating parts
- Fixations et boulons
- Composants automobiles
- Équipement marin
- Chemical and industrial machinery
Available Processing Services
Barre ronde en acier inoxydable can be supplied with cutting, polissage, usinage, traitement thermique, and customized size production according to project requirements.
