Stainless Steel 1.4017 1/4H vs 1.4017-CD

Stainless Steel · 1.4017 temper comparison

1.4017 1/4H and 1.4017-CD are two conditions of the same stainless steel grade, 1.4017: 1/4H (quarter hard) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. Both yield at about 500 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (quarter hard versus cold drawn). 1.4017-CD is the more ductile: elongation 15% versus 10% for 1.4017 1/4H, and 1.4017 1/4H is harder (210 HB vs 195 HB).

1.4017 1/4H vs 1.4017-CD — frequently asked

What is the difference between 1.4017 1/4H and 1.4017-CD?

1.4017 1/4H and 1.4017-CD are two conditions of the same stainless steel grade, 1.4017: 1/4H (quarter hard) versus CD (cold drawn). The chemistry is identical, so every difference below comes from the condition. Both yield at about 500 MPa — the mechanical properties are the same, and the difference is in how the stock is processed and what it is certified to (quarter hard versus cold drawn).

Which condition does FabDigit quote by default, 1/4H or CD?

Annealed is the default 1.4017 condition in the FabDigit quote flow (neither 1/4H nor CD). The other condition is available on request or by drawing note — specify it in the material field or the part notes and the quote is priced for it.

When should I choose 1.4017 1/4H over 1.4017-CD?

Pick 1.4017-CD when the part is bent, formed or impact-loaded.
