2mm Stainless Steel Round Bar: Small Diameter Range and Industrial Applications

2mm stainless steel round bar refers to a very small-diameter stainless steel rod widely used in precision engineering, medical devices, electronics, and fine mechanical components. It belongs to the category of micro or small-diameter stainless steel bars, where dimensional accuracy and surface quality are critical.

In practice, stainless steel round bars are not limited to a single size. The industry uses a continuous diameter range to meet different structural and processing requirements.

1. Stainless Steel Round Bar Diameter Range Overview

Category	Diameter Range	Typical Application
Micro bars	0.5 mm – 3 mm	Medical instruments, precision electronics
Small bars	3 mm – 10 mm	Shafts, fasteners, small mechanical parts
Medium bars	10 mm – 50 mm	Machinery components, structural parts
Large bars	50 mm – 200+ mm	Heavy industrial applications

A 2mm stainless steel round bar falls into the micro-diameter category and is often supplied in coils, straightened rods, or precision-cut lengths.

2. Characteristics of 2mm Stainless Steel Round Bar

Very high dimensional precision requirements
Excellent surface finish (often polished or bright finish)
High flexibility depending on grade
Suitable for fine machining and bending
Available in 304, 316, 201 and other grades

3. Common Grades Used in Small Diameter Bars

Grade	Features	Main Use
304	General corrosion resistance, good formability	Industrial and household components
316	Superior chloride resistance	Marine and chemical environments
201	Lower cost, moderate corrosion resistance	Decorative and general use

4. Applications of 2mm Stainless Steel Round Bar

Industry	Application
Electronics	Precision connectors and support pins
Medical	Surgical tools and guide wires
Automotive	Small shafts and control components
Model making	Structural frames and prototypes

5. Processing and Supply Forms

Cold drawn straight bars for high precision
Coiled wire rods for continuous processing
Cut-to-length precision rods
Polished surface or bright finish options
