Product Introduction
Cold Rolled Stainless Steel Hardness CSP Material
What Is Stainless Steel CSP Material?
Best For Elastic and Precision Parts
Which Stainless Steel CSP Specification Should You Choose?
Choosing the right stainless steel CSP material depends on the final application, hardness level, steel grade, forming process, required elasticity, dimensional tolerance, and surface condition. For springs, clips, connectors, terminals, and precision stamped parts, small differences in hardness, tensile strength, yield strength, thickness, and width can affect part performance and production yield.
Choose Stainless Steel Sheet Grades
301 CSP
Best for springs, connectors, clips, terminals, and precision electronic components that require high strength, elasticity, and spring performance.
304 CSP
Best for precision components that need corrosion resistance, forming stability, and reliable mechanical performance.
430 CSP
Best for applications that require ferritic stainless steel characteristics, magnetic properties, heat resistance, and cost efficiency.
201 CSP
Best for applications that need strength, forming performance, appearance, and cost control.
Choose by Hardness
1/2H
Suitable for applications that require moderate hardness, better formability, and stable strength.
3/4H
Suitable for precision parts that require higher strength and better spring performance than 1/2H.
FH / Full Hard
Suitable for parts that require high hardness, high tensile strength, and stronger elastic performance
EH / Extra Hard
Suitable for demanding elastic parts where maximum hardness and spring performance are required.

Availability note: Final availability may vary depending on stainless steel grade, hardness level, thickness, width, order quantity and customer specifications.
Choose by Thickness and Width
Thickness and width directly affect stamping performance, bending stability, spring force, dimensional accuracy, and material yield.
Genn-Hann supports CSP material production from 0.10–2.00 mm thickness and 4–1250 mm width, with coil inner diameter options of 300 / 400 / 508 mm. For high-precision applications, customers should confirm target thickness, width tolerance, hardness, grade, surface condition, and downstream process before ordering.
