08Cr17Ti vs 430 — frequently asked

What is the difference between 08Cr17Ti and 430?

Stainless Steel 08Cr17Ti and 430 are both stainless steel grades. Both yield at about 300 MPa — strength does not separate them. On the shop floor, 08Cr17Ti welds better (very good vs good) and 08Cr17Ti forms better (very good vs good).

Which is cheaper, 08Cr17Ti or 430?

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

Which welds better, 08Cr17Ti or 430?

08Cr17Ti. Its weldability rates very good (80/100) against good (60/100) for 430.
