Description de produit

High Quality Stainless Steel Round Bar 2mm–6mm
Precision-engineered stainless steel rods in grades 201/304/310/316/321/904L with cold drawn DIN standard HL surface for automotive parts and industrial applications.
Product Overview
High Quality Stainless Steel Round Bar (2mm-6mm) is a precision-engineered stainless steel rod designed for automotive parts, mechanical components, construction applications, and industrial manufacturing. Produced in grades such as 201, 304, 310, 316, 321, and 904L, this cold drawn stainless steel round bar delivers excellent surface finish, high dimensional accuracy, and superior mechanical strength.
Manufactured according to international standards including ASTM, DIN, JIS, EN, and GB, this product is widely used in industries requiring high precision, corrosion resistance, and stable performance under stress. Available surface finishes include 2B, BA, No.1, No.4, HL (Hairline), and polished finishes.
Industrial Challenges
Many industrial and automotive applications require small-diameter metal rods that can withstand:
  • High-speed mechanical movement and friction
  • Corrosive environments (moisture, chemicals, road salt)
  • High precision assembly requirements
  • Long-term fatigue resistance
  • Stable performance under vibration and load
Traditional carbon steel rods often fail due to rust, deformation, and wear, especially in automotive and outdoor environments.
Our Solution
Stainless steel round bars (2mm-6mm) solve these problems by offering:
  • Excellent corrosion resistance (especially 316, 904L)
  • High tensile strength and fatigue resistance
  • Precise dimensional tolerance (±1%) for machining accuracy
  • Smooth HL / polished surface for reduced friction
  • Long service life in harsh environments
  • Compatibility with CNC machining, bending, and cutting
This makes them ideal for automotive precision parts and industrial small components.

  • Fastening systems in harsh environments
How It Works
Stainless steel round bars function based on their alloy structure and surface properties:
Corrosion Resistance
Chromium in stainless steel forms a passive oxide layer that prevents rust and chemical attack.
Mechanical Strength
Grades like 304 and 316 provide balanced strength and ductility for dynamic loads.
Fatigue Resistance
Cold drawn processing improves grain structure, enhancing fatigue performance in automotive applications.
Surface Protection
HL and polished finishes reduce friction and improve wear resistance in moving parts.
Selection Guide
Selecting the correct stainless steel round bar depends on application needs:
Grade Recommended Use
201 Cost-effective indoor applications
304 General industrial and automotive use
304L Welding and corrosion-sensitive environments
316 Marine and chemical exposure
316L Strong acid and chloride environments
321 High-temperature applications
310 Heat resistance applications
904L Highly corrosive environments
Key Selection Factors
  • Environment (corrosion level)
  • Mechanical load and fatigue requirements
  • Diameter and precision tolerance
  • Surface finish requirement (HL / polished)
  • Budget and service life expectation
