The sample is immersed in a 6% hydrochloric acid solution of ferrous chloride at room temperature for 96 hours, and the weight change before and after the test is measured.
We will introduce the resistance to pitting corrosion test of "SIRICOROI." First, prepare a test solution of 6% hydrochloric acid and ferric chloride solution. The test specimens are produced from various materials under different heat treatment conditions. The surface roughness is adjusted using waterproof sandpaper #400, and degreasing is performed with acetone. Then, each material is immersed in the 6% hydrochloric acid and ferric chloride solution at room temperature for 96 hours, and the weight change before and after the test is measured using a precision balance to determine the degree of corrosion.

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.
