🧪 Alloying Elements & Mechanical Properties
Alloy steel used in Ratanex Alloy Steel Fasteners includes elements such as chromium, vanadium, molybdenum, tungsten, cobalt, and silicon. These enhance mechanical strength, hardness, thermal resistance and corrosion protection.
Ratanex ensures that all fasteners are heat treated — quenched and tempered — to meet performance benchmarks. Our products undergo testing such as tensile, Charpy impact, proof load, and PMI, with NABL-certified lab reports per EN 10204 3.1/3.2.
