18NiCrMo5 is one of the answers to keeping stainless steel pipe tough. This case-hardening steel brings strength and durability to your stainless steel piping and fittings. From gears to shafts, it handles wear and tear with ease. Let’s find out why it’s a favorite.
What Makes 18NiCrMo5 Special?
It is a nickel-chromium-molybdenum steel that rises to the occasion in tough working conditions. Hardened and easy to work with, it also strengthens stainless steel tubing and fittings. Let’s reveal its secrets step by step.
Chemical Composition of 18NiCrMo5
| Element | C | Ni | Cr | Mo | Mn | Si | P | S |
|---|---|---|---|---|---|---|---|---|
| Content (%) | 0.15-0.21 | 1.20-1.50 | 0.70-1.00 | 0.15-0.25 | 0.60-0.90 | ≤0.40 | ≤0.035 | ≤0.035 |
What We Do
Standards for 18NiCrMo5
- UNI 7846: Original Italian standard for 18NiCrMo5.
- EN 10084: Links to 17NiCrMo6-4 (1.6566), a near-equivalent modern grade.
- BS Equivalent: 817M17 (partial match).
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.
