Technical Specifications
Product Overview
Metallurgical Characteristics
MS 1700 is a precipitation-hardening martensitic stainless steel that achieves its exceptional strength through a combination of martensitic transformation and age-hardening mechanisms. The steel's microstructure consists of tempered martensite with fine carbide precipitates, providing an optimal balance of strength, toughness, and corrosion resistance.
Heat Treatment Process
MetalZenith employs a sophisticated heat treatment process for MS 1700, beginning with solution treatment at 1050°C followed by rapid cooling. The material is then aged at 480-510°C to achieve peak hardness and strength. Our computer-controlled furnaces ensure precise temperature uniformity and atmosphere control throughout the process.
Manufacturing Process Excellence
Our manufacturing process begins with vacuum induction melting using high-purity raw materials, followed by electroslag remelting for enhanced cleanliness. Hot working is performed within carefully controlled temperature ranges to optimize grain structure. Cold working and precision machining capabilities allow us to deliver components to exact specifications with superior surface finish.
Quality Standards & Testing
Every batch of MS 1700 undergoes comprehensive quality testing including chemical analysis by optical emission spectroscopy, mechanical property verification, microstructural examination, and non-destructive testing. Our quality management system complies with ISO 9001:2015, AS9100D, and NADCAP requirements, ensuring consistent performance and traceability for critical applications.
