OHNS
OHNS (Oil Hardening Non Shrinking) steel is a type of high-carbon, high-chromium tool steel primarily used in the manufacturing of dies, punches, and similar precision components. It's known for its excellent wear resistance, high hardness, and good dimensional stability.
OHNS steel undergoes various quality control tests, including chemical composition analysis, mechanical testing (tensile, hardness), microstructure examination, and ultrasonic testing. OHNS steel is highly valued for its excellent wear resistance, high hardness, and dimensional stability, making it suitable for a wide range of precision tooling and die applications. Proper heat treatment and processing are essential to achieve the desired mechanical properties for specific applications.
