Nickel Alloy ENiCrCoMo-1 vs ENiCrMo-1

Nickel Alloy · grade comparison

Nickel Alloy ENiCrCoMo-1 and ENiCrMo-1 are both nickel alloy grades. Both yield at about 430 MPa — strength does not separate them. ENiCrCoMo-1 is harder — 210 HB against 195 HB for ENiCrMo-1 — which matters for wear surfaces and threads. ENiCrCoMo-1 is stiffer (211 GPa vs 196 GPa) and ENiCrCoMo-1 runs hotter in service (1,100°C vs 540°C continuous). On the shop floor, ENiCrCoMo-1 welds better (excellent vs very good).

ENiCrCoMo-1Choose it when surface hardness matters, or when the part sees heat.

ENiCrCoMo-1 vs ENiCrMo-1 — frequently asked

What is the difference between ENiCrCoMo-1 and ENiCrMo-1?

Nickel Alloy ENiCrCoMo-1 and ENiCrMo-1 are both nickel alloy grades. Both yield at about 430 MPa — strength does not separate them. ENiCrCoMo-1 is harder — 210 HB against 195 HB for ENiCrMo-1 — which matters for wear surfaces and threads.

Which is cheaper, ENiCrCoMo-1 or ENiCrMo-1?

Both sit in the same relative cost tier ($$$$, high); the part price will be decided by machining time, tolerance and quantity rather than by the material.

Which welds better, ENiCrCoMo-1 or ENiCrMo-1?

ENiCrCoMo-1. Its weldability rates excellent (85/100) against very good (70/100) for ENiCrMo-1.
