AISI 5160 is a chromium-equipped, high-carbon spring steel renowned for its outstanding toughness, fatigue resistance, and ductility. With approximately 0.60–0.70% C, 0.75–1.00% Mn, 0.20–0.40% Si, and 0.80–1.10% Cr, 5160 combines high strength with excellent spring-back characteristics, making it a staple in automotive leaf springs, knife blades, suspension components, and industrial springs. This guide covers its […]

Stainless steel and high carbon steel represent two pillars of the steel industry, each engineered for distinct performance profiles. Stainless steel excels in corrosion resistance and formability, while high carbon steel offers superior hardness and wear resistance. This guide dissects their compositions, mechanical properties, corrosion behavior, fabrication considerations, applications, market trends, sustainability aspects, emerging technologies,

Carbon steel—defined by its carbon content ranging from 0.05% to over 1.5%—accounts for roughly 90% of global steel production. Its versatility spans from mild, easily machined low-carbon steels to high-carbon tool steels with exceptional hardness. This guide unpacks the AISI/SAE classification system, details the chemical and mechanical characteristics of low, medium, high, and ultra-high carbon

What Is EN45 High Carbon Steel? EN45 (also known as 55SiMn7 or BS970 250A58) is a silicon-manganese spring steel containing approximately 0.55% carbon, 0.7–1.0% manganese, and 1.5–2.0% silicon. Designed for oil hardening and tempering, it offers an excellent balance of strength, elasticity, and fatigue resistance, making it ideal for springs, blades, and other load-bearing components.
