1. The Key Role of Stainless Steel in Stamping Manufacturing
In the metal stamping industry, material selection is the most critical factor affecting product quality, consistency, and durability.
Among all materials, stainless steel stands out for its superior strength, corrosion resistance, aesthetics, and formability—making it widely used in the automotive, appliance, construction, and medical sectors.
With over 40 years of experience, GennHann Stainless Steel Co., Ltd. has mastered every aspect of stainless steel behavior and application.
2. Common Stainless Steel Grades for Stamping Applications
304 Stainless Steel: The Universal Standard for Corrosion Resistance
304 is the most widely used austenitic stainless steel grade, offering excellent corrosion resistance and formability.
It is commonly used in tableware, medical equipment, home appliance housings, and architectural finishes.
GennHann supplies both 304 and 304L grades, with thicknesses ranging from 0.3mm to 6.0mm, precisely cut and polished to ensure consistent dimensions and surface quality for stamping parts.
316 / 316L Stainless Steel: High-End Choice for Chloride Environments
Containing molybdenum, 316 offers enhanced resistance to chlorides and harsh environments—ideal for marine equipment, chemical containers, and medical components.
GennHann utilizes advanced Italian IMEAS polishing technology, providing surface finishes such as No.3, No.4, and HL, achieving both aesthetic and corrosion-resistant results.
430 Stainless Steel: Cost-Effective Structural Material
As a ferritic stainless steel, 430 offers magnetic properties and excellent value for cost-sensitive applications.
It is widely used in appliance interiors and general structural parts.
GennHann provides cold and hot rolled plates (0.3mm–6.0mm), combined with PVC protective films and precision leveling, minimizing surface damage and deformation risks.
201 / 202 Stainless Steel: Lightweight and Economical Solutions
With higher manganese and lower nickel content, these grades deliver good ductility and strength at a lower cost.
GennHann’s precision slitting lines (minimum width: 4mm) make these grades suitable for electronics, appliance panels, and decorative components, balancing performance with cost efficiency.
Comparing the Three Main Series: 200, 300, and 400
Series | Structure Type | Common Grades | Key Features and Stamping Considerations |
300 Series | Austenitic | 304, 316, 301 | Excellent ductility, ideal for deep drawing; requires high stamping pressure due to work hardening. |
400 Series | Ferritic / Martensitic | 430, 409 | Magnetic, economical; moderate ductility, suited for general stamping parts. |
200 Series | Austenitic | 201, 202 | High Mn, low Ni; fair ductility, slightly less corrosion resistance than 300 series. |
The Relationship Between Thickness and Stamping Quality
Choosing the correct sheet thickness is essential for balancing strength, weight, and production cost.
- Thick Sheets (>2mm) – Used for load-bearing parts requiring rigidity and resistance to deformation.
- Thin Sheets (<1mm) – Suitable for deep drawing and complex geometries.
GennHann offers materials from 0.3mm to 6.0mm, equipped with six-level precision leveling machines to ensure flatness and uniform stress distribution.
This reduces warping and spring-back during stamping, significantly improving consistency and yield rate.
