Blue & Yellow Tempered Strips: What’s the Difference?
When it comes to hardened and tempered steel strips, color isn’t just cosmetic—it tells a story about the material’s heat treatment and performance characteristics. For manufacturers working with springs, blades, saws, or precision parts, knowing the difference between blue and yellow tempered steel strips can save you time, reduce production issues, and even extend product […]
How High Carbon Steel Balances Strength and Toughness
When you’re choosing a material for blades, ressorts, or wear-resistant parts, you want one that doesn’t just look good on paper—you want something that performs under pressure. High carbon steel often enters that conversation because of one critical promise: it balances strength and toughness. But how does it do that? And what does it mean […]
C75S Spring Steel: Comprehensive Analysis of Properties, Processing & Application Guide
I. Material Overview & Standardization C75S is a high-carbon, non-alloy spring steel standardized under the German DIN EN 10132-4 specification. It corresponds to Chinese GB/T 75, American AISI 1075, and Japanese JIS S75CM standards. Its core characteristics are a high elastic limit and excellent fatigue resistance. Under comparable surface conditions and full hardenability, its fatigue […]
