- 描述
Stainless steel round bar is widely used in machining, 建造, 汽车零部件, 紧固件, 和工业装备制造. One of the most important selection factors is material grade, because different stainless steel grades determine corrosion resistance, 力量, 机械加工性, 及应用范围. Common stainless steel round bar grades mainly come from austenitic, 铁素体, 马氏体, and duplex families.
奥氏体不锈钢牌号
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
铁素体不锈钢牌号
- 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
马氏体不锈钢牌号
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
双相不锈钢牌号
- 2205: most common duplex grade with high strength and corrosion resistance
- 2507 (超级复式): 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
- Suitable for cutting, 转身, and CNC machining
典型应用
- 机械轴及旋转部件
- 紧固件和螺栓
- 汽车零部件
- 船用设备
- Chemical and industrial machinery
