Technical Specifications
Product Overview
Metallurgical Characteristics
HY-130 exhibits a tempered martensitic microstructure achieved through controlled quenching and tempering processes. The low-alloy composition with nickel, chromium, and molybdenum additions provides exceptional hardenability and strength while maintaining good toughness. The fine-grained structure ensures uniform mechanical properties throughout the cross-section.
Heat Treatment Process
MetalZenith employs austenitizing at 870-900°C followed by water quenching and tempering at 580-620°C. Our controlled cooling rates and precise temperature monitoring ensure optimal transformation kinetics and mechanical property development. Post-heat treatment stress relief is performed when required for structural applications.
Manufacturing Excellence
Our production process includes vacuum degassing, controlled rolling, and precision heat treatment in computer-controlled furnaces. MetalZenith's advanced manufacturing ensures consistent chemistry, refined grain structure, and superior mechanical properties essential for ultra-high strength structural applications.
Structural Quality Testing
Comprehensive testing includes Charpy V-notch impact testing at various temperatures, fatigue crack growth rate evaluation, weldability testing per AWS D1.1 procedures, and accelerated atmospheric corrosion testing. Our quality assurance ensures reliable performance in critical structural applications.
Engineering Applications
HY-130's exceptional strength-to-weight ratio makes it ideal for weight-critical structural applications. In bridge construction, it enables longer spans with reduced material usage. For machinery manufacturing, it provides superior load-bearing capacity. In vehicle construction, it offers enhanced protection while minimizing weight penalties.
