شريط مسدس من الفولاذ المقاوم للصدأ: Common Specifications and Size Standards
Stainless steel hexagon bar (also called hex bar or hexagonal stainless steel rod) is widely used in machining, إنتاج السحابة, mechanical components, and engineering structures. Its six-sided geometry provides excellent grip for machining operations and is ideal for bolts, المكسرات, and precision parts manufacturing.
The most important factor when selecting stainless steel hex bars is understanding the standard size range, across flats (AF) أبعاد, and length tolerances used in industrial supply.
Common Size Range of Stainless Steel Hexagon Bar
Stainless steel hex bars are typically defined by the distance across flats (AF), which determines the bar’s size and application suitability.
| Size Category | Across Flats (AF) | Equivalent Use |
|---|---|---|
| Small Hex Bar | 3mm – 10mm | Precision screws, small fasteners |
| Medium Hex Bar | 10mm – 30mm | General machining parts, البراغي |
| Large Hex Bar | 30mm – 80mm | Heavy-duty mechanical components |
| Extra Large Hex Bar | 80mm – 120mm+ | Industrial structural parts |
Standard Length Specifications
Hexagon bars are commonly supplied in standard lengths suitable for machining and industrial fabrication.
- Standard length: 3 متر
- Standard length: 4 متر
- Standard length: 6 متر
- Custom cutting available according to requirements
Dimensional Tolerance and Precision Grades
Different manufacturing processes provide different levels of precision depending on application requirements.
| Processing Type | Tolerance Grade | جودة السطح |
|---|---|---|
| Hot Rolled Hex Bar | Standard tolerance (±0.5mm to ±1mm) | سطح خشن |
| Cold Drawn Hex Bar | دقة عالية (h9 / H11) | سطح أملس |
| Bright Hex Bar | Very high precision | Polished finish |
Common Stainless Steel Grades for Hex Bars
Hexagon bars are available in different stainless steel grades depending on corrosion resistance and mechanical requirements.
- 304 / 304ل – General-purpose corrosion resistance and machining
- 316 / 316ل – Marine and chemical environments
- 303 – Improved machinability for fastener production
- 410 / 420 - صلابة عالية ومقاومة التآكل
- 17-4الرقم الهيدروجيني – High-strength precision engineering applications
خيارات إنهاء السطح
- Hot rolled black surface – structural and heavy-duty use
