Core Advantages of 18NiCrMo5
Hardness of 58-62 HRC after carburizing.
This durability excels in harsh environments such as conveyor systems or heavy machinery.
Possessing great toughness, it prevents stainless steel tubes from cracking under high pressure or sudden impact. Assures reliability for demanding tasks such as automotive gear systems.
Machining in the annealed condition is effortless and speeds up the production of stainless steel fittings. This not only saves time, but also provides accurate parts without additional effort or cost.
Can be hardened uniformly in all sections, ensuring that stainless steel tubing remains strong wherever it is used. This consistency improves performance in large applications such as industrial piping.
