High-performance stainless steel "Silicolloy" *Hardness conversion table / Various properties of SUS630
Technical handbook available! From H900, which emphasizes hardness, to H1150, which focuses on toughness! There are 4 types of heat treatment!
"SUS630" is a representative steel of precipitation hardening stainless steel, combining corrosion resistance and high strength. After solution heat treatment (solid solution heat treatment) at 1020 to 1060°C, precipitation hardening heat treatment (aging heat treatment) is applied to precipitate a Cu-rich phase, resulting in high strength and high hardness. This document includes "an example of chemical composition," as well as "heat treatment standards" and "hardness conversion tables" presented in tables. Please take a moment to read it.

Company information
Silicolloy is a revolutionary new material that contains a large amount of silicon (silicon) and was developed using pure domestic technology. Silicolloy is a super alloy that possesses high strength, heat resistance (high-temperature oxidation resistance), corrosion resistance, wear resistance, high hardness, and low dimensional changes during heat treatment, all in one steel. Currently, many engineers (technicians and designers) are advancing its commercialization, contributing to new product development and total cost reduction through extended product lifespan. There are 'Silicolloy A2', which excels in overall balance as a precipitation-hardened stainless steel, and 'Silicolloy XVI', which has the highest hardness in the world as a precipitation-hardened type. Those who require both corrosion resistance and high hardness should definitely take note! In 2025, a new material called 'Axia Zero Series' will be developed. This new material is a precipitation-hardened stainless steel that not only has high corrosion resistance and high hardness but also high strength and high durability. 'Axia Zero3' achieves high hardness of 56-58 HRC, high corrosion resistance equivalent to austenitic types, and high strength in the 2000 MPa range. It features hardness obtained through precipitation hardening treatment at 480°C, which minimizes deformation and dimensional changes due to heat treatment and resolves various issues related to quenching.
